Operating Manual - nX, nXe, and nXp Power Ampliers
 2 nX INSTALLATION REQUIREMENTS
Before connecting to AC mains power, make sure that the mechanical installation, cooling requirements, wiring, controls, and
software are all set to the conguration needed for your particular application. Failure to do so could result in damage to the
unit or to other components in the system.
2.1 AC Mains Voltage, Power, and Current Requirements
This amplier will auto-detect AC mains voltage of 110-120VAC or 220-240VAC, 50-60Hz. At nominal 120VAC mains, the
allowed operating range is 70-135VAC to allow for brownouts or power surges, and for nominal 240VAC operation the range is
140-270VAC. Use only the provided AC cord or equivalent to connect to AC mains. Programmable Power-On Delay is available
on nXe and nXp series ampliers. All nX models have a xed, non-defeatable warm-up delay of about three seconds to protect
against excessive in-rush current when rst powered up or when waking from sleep. The model number and power consumption
are indicated on the back panel label placed above the AC inlet. To reduce the risk of ground loop hum, all sound system ground
references should originate at the same AC power distribution point. Do not lift or remove the amplier power cord ground pin.
AC Mains Connector Types - The following table shows the AC mains plug type supplied with each nX amplier model,
as well as the required receptacle. A detachable 20A Neutrik PowerCON®mains chassis connector is installed on all models
except for nX 3.04, which uses a 30A PowerCON®.

2.2 Input Signal Wiring
Use shielded wiring for balanced or unbalanced audio signals. Shielding which is properly grounded will protect the signal from
outside electrical interference such as RF, uorescent lighting, and computer/display emissions. Unbalanced or single-ended (tip-
sleeve) lines of less than 10 feet are generally ok, but for greater distance or noisy eld environments, always use balanced signal.
Each channel's Euroblock, 1/4" phone jack, and XLR inputs are wired in parallel, with XLR pin 2 (+) and pin 3 (-). When using an
unbalanced input, wire the hot signal to the input (+) euroblock pin, phone jack tip, or XLR pin 2, and also be sure to wire the input
(-) pin, phone jack ring, or XLR pin 3 to ground. Do not leave the (-) input unconnected. Avoid running low level signal wires in
close proximity or parallel to long speaker cables, AC power cables, or power transformers, as they can induce hum or oscillation.
2.3 Output Speaker Wire
Note: The sound system installer is responsible for using loudspeaker wiring that is in compliance with local
electrical code. The following recommendations for speaker wiring are based on UL 60065 section 5.2-d and the US National
Electrical Code Article 725. These are only guidelines, consult your local code for specic up to date requirements.
Class 2 wiring is typically used when the maximum measured open-circuit speaker output voltage is less than 120V r.m.s. Class 3 wiring
is typically used if the measured open circuit output voltage exceeds 120V r.m.s, such as when 70V, 100V, or low-Z ampliers are used
in bridged mode. See section 15 for specic model congurations that may require Class 3 speaker wiring.
Output Speaker Connectors: nX amplier speaker outputs use Neutrik SpeakON connectors because they are safe, secure, reliable,
and fully enclose any hazardous voltage.
Wire guage: nX ampliers are capable of delivering high levels of output current, so the wire gauge used for speaker outputs is im-
portant. Inadequate wire gauge, especially over long distance, adds signicant resistance to the speaker’s own impedance, reducing
the power which is actually delivered to the speaker. It could also result in a decreased damping factor and potential re hazard. Since
power at the speaker load is of primary concern in system design, refer to the table below to best determine appropriate wire gauge for
your application. The following table lists the resistance per 100 feet of common copper wire gauges, and also lists the percentage of
the speaker load power which would be lost as heat in an arbitrary 100 ft run of different gauges of 2-conductor copper speaker wire.
Wire gauge resistance/power loss for 100ft speaker cable
Wire Gauge Ohms/100ft 8 Ohm load 4 Ohm load 2 Ohm load
#8 0.0605 Ohms 0.8% 1.5% 3%
#10 0.1018 Ohms 1.3% 2.5% 5%
#12 0.1619 Ohms 2.0% 4.0% 8%
#14 0.2575 Ohms 3.2% 6.4% 12.8%
#16 0.4094 Ohms 5.1% 10.2% 20.4%
#18 0.6510 Ohms 8.1% 16.3% 32.6%
This table expresses the power loss as a percentage of the load’s power rather than the total amplier output power in order to ac-
curately determine power loss at other cable lengths. For example, if you plan to deliver 150 watts to an 8 Ohm load through 50 ft of
14 ga. cable, the power loss in the cable would be half that of a 100 ft run of #14 wire as shown in the table, or 1.6% of 150W, which
is an insignicant 2.4 watts. However, if you were to run 200 ft of 18 ga. cable to a 2 Ohm load, the loss would be twice that of the
100 ft run shown in the table, or 65.2% of 250W, which is 163 watts lost as heat. Always be sure to use adequate gauge speaker wire.
2.4 Remote Control Wire
Remote DC level control (all models) - Unshielded bell or telephone wire is sufcient for DC level control, as is CAT5 cable.
The V+ and GND pins from one amplier channel can be shared with other remote DC level controls wired to the same ampli-
er, however do not connect this ground to any external grounds.
Remote Standby (nXe and nXp only) - This is a logic level signal, use unshielded low gauge wire.
Fault (nXe and nXp only) - This is also a logic level signal, unshielded low gauge wire is adequate.
Preset (nXe and nXp only) - This is also a logic level signal, unshielded low gauge wire is adequate.
Data (nXe and nXp only) - Four conductor telephone wire is suitable, as well as CAT5, but if shielded wiring is used be sure
to ground the source end of the shield. Under no circumstances should shielding be left unconnected to ground, as the added
line capacitance will degrade the data signal. Maximum data cable distance is 1,000 ft (305m).

Operating Manual - nX, nXe, and nXp Power Ampliers
2.5 Aux Output Wiring (nXe and nXp only)
The aux outputs are pseudo-balanced, meaning they use single ended signal (+) but with balanced impedance, and can be wired
balanced or unbalanced. Always use shielded cable for audio signals.
2.6 Mechanical
Each amplier model is 2RU, and is designed to t in a standard 19-inch equipment rack. Use four screws when mounting
the amplier to the front rack rails. Rear support is recommended for mobile or touring use (see mechanical drawing below).
In some installations where the sound system is exposed to a high level of RF noise or system-induced oscillation, it may be
necessary to ground the amplier’s chassis to the rack enclosure. This is accomplished using star type lockwashers on the four
rack mounting screws, placed between the amplier chassis and the rack rails. These star washers will penetrate through the
amplier and rack rail nish to adequately ground the chassis to the rack.
2.7 Cooling
Air vents on the amplier front and side panels must have access to free owing room temperature air. Cool air is drawn in
through the sides and blown out the front. It is not necessary to leave empty rack spaces above or below the amplier. See the
BTU/hr chart below for amplier thermal output characteristics.

 3 nX AMPLIFIER PROTECTION
Power-On Delay - All models have a three second warm-up delay to prevent excessive in-rush current when rst powered on or
awakened from sleep. nXe and nXp models additionally offer programmable Power-On Delay of up to 25 seconds (see section 9.2).
Thermal Protection - Cooling fans are continuously variable, reaching their maximum speed when an amplier channel reaches
80% of it's safe operating temperature, also turning on theTemp LED. At 90%, the Protect LED turns on to indicate countermea-
sures have been applied to attenuate the input signal to the overheating channel. A Temp LED turns on dim at rst, then increases
in brightness as the amp channel approaches maximum safe temperature. 100% critical temperature will shut down the amplier.
Overpower Protection - To protect internal components against overpower conditions, a protection scheme in each output stage
reduces audio output power until the fault condition is no longer present.
Output DC and Rail Fault Protection – Output DC on any channel will trigger the Protect LED and mute that channel. Voltage
rail irregularities such as power supply pumping are also detected and compensated for in real time as the amp runs.
AC Mains - If the AC Mains line voltage exceeds or falls below the specied operating range, the amplier will temporarily
shut down. It will automatically restart as soon as the AC line voltage returns to the specied range.
For details on these and other amplier protection schemes, plus their LED codes, refer to Troubleshooting in section 14.
 4 nX FRONT PANEL FEATURES (all models)
4.1 Mounting Holes – For mounting to a 19" equipment rack.
4.2 Air Vents – Cool air enters in through the amplier sides and is vented out the front.
4.3 Reset/Sleep Mode/Disable Switch – This recessed switch is used to reset the amplier to its default factory settings,
however it will not erase amplier presets. Proteane software must be used to erase amplier presets (sec 9.2g). This switch is
also used to set sleep mode and front panel disable status (see below).
To reset amplier settings, routing, networking, and security (not presets) to original factory defaults, use a plastic paper clip
or equivalent to press and hold the switch during power up until all channel LEDs sequence
from bottom to the top. Release the switch before the LED sequence is complete to cancel
the process. Upon completion, all LEDs turn off and the amplier resumes normal operation.
Setting Sleep and Front Panel Disable Mode - The factory reset switch is also used to select
one of four sleep and front-panel-control-disable modes as illustrated to the right. The default
status is Sleep and Disable OFF (Mode 1). To advance to the next mode, press and hold this
switch when the amplier is fully on, and the four mode combinations will cycle and repeat.
To select a mode, simply release the switch when the desired mode is displayed.
The Disable LED is lit any time the front panel controls are disabled, either by selecting disable
mode from this switch or using software control.
The sleep LED turns on during the mode-select cycle whenever sleep mode is enabled, but turns
back off as soon as the switch is released, remaining off unless the amp actually goes to sleep.
The current sleep mode status can be displayed when the amp is fully on by quickly pressing
and releasing the reset switch. If the sleep LED lights, sleep mode is active.

Operating Manual - nX, nXe, and nXp Power Ampliers
4.4 Channel Attenuators – These control the input signal level to the amplier, and work in conjunction with the remote DC
fader level controls and the software control surface fader controls (if the amp is networked). When an input attenuator is turned
fully off, it's red Clip/Mute LED turns on and stays on to indicate mute status for that channel. The front panel attenuators can be
disabled, along with the power switch, using the factory reset switch as shown in section 4.3 or using software.
4.5 Channel LED Indicators
BRIDGE - This green LED indicates when the channel pair is congured to BRIDGE mode from the back panel switch. Only
the odd numbered input and level control for that channel pair is used.
TEMP - This yellow LED turns on when an amplier channel has reached an operating temperature that is 80% of it's maxi-
mum safe range, and the cooling fan(s) are at their maximum speed. The LED lights dimly at rst and will glow brighter if the
temperature increases.
CURRENT - This green LED lights proportionately with the output current delivered to the speaker load.
SIGNAL - This green LED lights when the output voltage reaches -18dB from full output.
CLIP/MUTE - CLIPPING: The red LED indicates clipping when speaker output is 1dB below rated output, or when the input
preamp signal is clipped. MUTE: The LED indicates mute when the channel is muted or when it's level control is fully attenuated.
Additionally, the Clip/Mute LED is used along with the Protect LED to indicate an output DC fault (see section 14).
4.6 Amplier Status LEDs
PROTECT - The red Protect LED initially turns on to indicate that real-time countermeasures are being applied to overpower, over-
temperature, or rail voltage fault conditions while the amp is still running. If those countermeasures are unsuccessful and the amplier
protects itself by shutting down, the Protect LED remains on and the amplier's power must be cycled before resuming normal operation.
The exception to this is when the amp shuts down due to the AC Mains voltage being out of range, in which case the amp automatically
restarts as soon as the AC mains line voltage returns to the specied operating range . See section 14 for full details .
SLEEP - This blue LED indicates that the amplier is asleep. Sleep mode can be enabled as a power saving feature that shuts
down most amplier circuits after a period of audio inactivity, reducing the amplier's power consumption to less than 1 Watt. An
amplier is awakened when there is audio signal present again, or when the power switch is pressed. Because the real-time-clock
is also shut down during sleep mode, the amplier cannot be awakened by any software function, including the event scheduler.
Sleep mode is normally disabled, therefore must be enabled by the user. On nX series, the sleep clock timer is xed at 30 minutes,
and is enabled by toggling through the four mode conditions of the factory reset switch as detailed in section 4.3. On networked
nXe and nXp series, the sleep clock timer also defaults to 30 minutes, but is programmable under [Device Options] with a range
of 1-120 minutes. In all models, the presence of input signal above -24dBu (0.05Vrms) or pressing the power switch will return
the amplier to normal operation. On all models, a xed amplier turn-on delay of three seconds is necessary to manage in-rush
current during power-up or waking from sleep. Sleep mode has priority over standby mode.
DISABLE - This yellow LED lights when the front panel power switch and level controls have been disabled. All front panel
controls are disabled together using the factory reset switch as described in section 4.3, or in software using the amplier's main
control surface (see section 9.4a).
COM - For nXe and nXp models only, this green LED lights whenever network communication occurs. Secondly, the COM LED
ashes for two seconds when the <Identify Device> software button for that device is clicked. (see section 9.1i) Lastly, the COM LED
becomes lit (along with the ashing power switch LED) during ash reprogram mode.
4.7 Power Switch/LED – This switch is used for powering the amplier on or off or waking the amplier from sleep. The
white switch LED lights solid when the amplier is on, and ashes when in standby mode (nXe and nXp only). The power switch
can be disabled using the factory reset switch actions described in section 4.3, or disabled from software (nXe and nXp only). The
three possible power switch LED conditions are:
1) Fully lit: The amplier is powered up, even if the power switch has been disabled, in which case the disable LED will be on.
2) Flashing: The amplier is in standby mode, or is in ash reprogram mode when the COM LED is also lit.
3) Fully off: The amplier is either completely off, or it is in sleep mode, in which case the blue sleep LED will be on.
4.8 Series and Model Labels – The label on the left indicates the amplier series, nX, nXe, or nXp. The label on the
right shows the amplier model name.

 5 nX SERIES REAR PANEL FEATURES
5.1 Channel Conguration DIP Switch - The DIP
switches congure each channel's 80Hz 2nd Order Hipass
Filter, Output Clip Limiter, Amplier Gain, and Output
Mode. In the example to the right, the DIP switch is set as
follows: 6: 80Hz High Pass Filter is Off; 5: Clip Limiter is
On; 4&3: Gain is 1.4V; 2&1: Output Mode is Low Z.
Note: The Gain setting of 1.4V means that a 1.4V input will drive
the amp to full output in any output mode. The other three Gain settings will apply their
respective amplier gain regardless of output mode, so the actual input voltage required
to fully drive the amp will vary based on the selected output mode.
5.2 Euroblock Input Jack - Used for wiring a balanced input. If using an unbalanced
signal, wire the input signal to the (+) pin, the shield to (G), and wire the (-) input pin to
ground. Euroblock pins are wired in parallel to the 1/4" TRS and XLR combo jack.
5.3 Remote DC Level Control - Each channel has a potentiometer circuit available for
remote DC Level Control. The example to the right illustrates a typical DC level control application.
There is no limit to wire length, but do not use any other ground source. If multiple remote DC level
controls are used for different channels, the same ground and V+ sources can be shared.
5.4 Combo Input Jack - The combination 1/4" TRS and XLR jack (pin 2 hot) is wired in
parallel to the euroblock input. Do not oat the TRS ring or XLR pin 3, connect it to (-) signal or
to ground (if unbalanced).
5.5 Bridge Mode Switch - This switch places an adjacent
channel pair into bridge mode, combining two amplier outputs
for more power to a single speaker load. Bridge mode uses only the
odd numbered input channel and level control, disabling the even
numbered input. Speaker outputs for bridge mode must be wired
according to the chart shown to the right. The bridge mode switch
button can be removed for added security by pulling it straight off.
5.6 SpeakON®Output Jack Wiring - SpeakON output
jacks provide safe, secure, and reliable loudspeaker connections,
preventing external contact with potential hazardous voltage. See the speaker wiring diagram above or on the amplier back panel for
SpeakON pin connections and channel assignments for normal or bridge mode speaker wiring. See sec 5.5 to use bridge mode.
5.7 PowerCON®AC Mains Connector - Always use the AC cord provided by Ashly for connecting to mains power. The
amplier auto-detects mains voltage from 120VAC to 240VAC. WARNING: Do not remove or lift the mains connector ground.
5.8 Serial Number Sticker - This sticker identies the product model number, serial number, MAC address (if network-
able), and AC mains current/power rating.

 6 nXe SERIES REAR PANEL FEATURES
The following nXe features are in addition to standard features found in nX series ampliers:
6.1 Ethernet Port - This RJ-45 connector offers Ethernet control and monitoring of the amplier using Proteane software.
See section 8 in this manual for details on Ethernet communications.
6.2 Network Audio - This is for an optional factory installed CobraNet or Dante network audio module
on nXe and nXp models. See section 13 for details.
6.3 Standby Contact Closure - The STBY pin, when connected to the ground pin (G) as shown,
will remotely place the amp into standby mode. When the connection is opened, the amplier returns to
normal operation. The front panel power switch will ash when the amplier is in standby.
6.4 Fault Pins - A fault logic output pin is available for each amplier
output channel. Fault pins are used to drive external LEDs or connect
with equipment that can remotely monitor or respond to a serious ampli-
er problem. A fault is indicated by the loss of a normally present "heartbeat" signal, where the
output continuously toggles between 0V and +5V at a 1Hz rate.
The normal heartbeat signal on each fault pin is interrupted
whenever a fault condition prevents normal function of that
channel while the amplier is either powered on or in the
standby state. Fault conditions include loss of AC mains
voltage, excessive internal temperature, power supply
voltage out of range, DC on output, or microprocessor
malfunction. A fault pin output can directly drive an LED
as shown in the circuit illustration to the right.
If a fault occurs, fault pin output may be latched <Low> or
<High> depending on the type of fault or state of the output
at the moment the fault occurred. A fail-safe fault detection
circuit should monitor and respond only to the loss of the
1Hz heartbeat signal.
6.5 Preset - Each pin (P1 through P4) can be connected to the adjacent ground pin (G) via Ashly's WR-2 remote or other contact closure
to recall a stored preset or sub preset from the amplier. Preset pins 1-4 correspond directly to amplier presets 01 - 04.
6.6 Serial Data Connector - These four pins (G, +18, OUT, IN) are for connecting a serial data remote control such as an Ashly
WR-5 or RD-8C. Ashly also offers an in-line converter called the INA-1 which allows the data port to be used with third party RS-232 con-
trollers. A technical RS-232 protocol document is available on the Ashly website for third party developers. See more data remote control
application details in section 10.
6.7 AUX Outputs - These Euroblock connectors provide preamp signals for driving other ampliers. See the block diagram
on page 59 for the differences between two and four channel amplier AUX outputs. AUX outputs are pseudo-balanced, meaning
they use single ended signal with balanced impedance, and can be wire balanced or unbalanced.
6.8 AES3 Digital Audio I/O Option - This is used for Ashly's two or four channel AES3 input and pass-through module,
available as a factory installed option on nXe and nXp models. See section 12 for AES3 details.

 7 nXp SERIES REAR PANEL FEATURES
*The following nXp features are in addition to all of standard features found in nX and nXe series ampliers:
7.1 Installed DSP - Factory installed DSP allows for comprehensive signal processing of amplier signals (section 9.4d)
as well as loudspeaker load impedance analysis (section 9.1i).
7.2 Network Audio - CobraNet or Dante network audio modules can be factory installed in nXe or nXp models.
7.3 AES3 Digital Audio I/O - AES3 digital audio module can be factory installed in nXe or nXp models.
 8 ETHERNET COMMUNICATIONS (nXe and nXp models only)
Ethernet communication is made by connecting the amplier directly to a PC running Proteane software or connecting through a network router,
switch, hub, or patch panel using Cat-5, Cat-5e, or Cat-6 wiring. Maximum Ethernet cable distance is 100 meters (328 ft). Ashly nXe and
nXp ampliers will adapt to either a straight through pin to pin or crossover Ethernet cable. For wireless iPad control using a custom "Ashly
Remote" user interface, the iPad must be connected to a wireless access point that is connected to the same network (subnet) as the amplier.
8.1 IP Address - There is no need to assign an IP address to nXe ampliers. The router or Link Local Addressing will assign
IP addresses to each device automatically.
When a router is not available, each amplier will acquire it's own IP address based on Link Local Addressing. This allows the
device to operate without the need to set up static IP address. If the only option is to use an Ethernet switch instead of a router,
and communications problems remain which cannot be solved with the use of the link local standard, each device can have
a static IP address assigned from within Proteane software. This is done by selecting “Manual Conguration” in the Network
Properties tab of each device, where the system/network administrator must assign each product its’ own unique static IP ad-
dress, each with the appropriate sub net if applicable.
8.2 Firewalls - If Proteane software does not detect the amplier or show real time changes, the rewall in the host PC may need to
have Proteane software added to its rewall exceptions, since rewalls may block the amplier response to the PC. The current PC rewall
status is found by clicking on the Windows Start button, then Control Panel, then double clicking on the security shield where rewall
exceptions are congured.
8.3 Wi-Fi and LAN – For the initial device auto-conguration process, any secondary Wi-Fi connection should be disabled on
the PC, and the LAN (Local Area Network) connection must be enabled on the PC. Secondary network connections may confuse the
auto device discovery process. Go to the Windows Control Panel, then Network Connections, to disable any secondary network con-
nections. Once communications with the device is established, secondary network connections can be enabled again.
8.4 Connecting Device(s) - Connect the Ethernet cable from the PC or network to the amplier. If a successful Ethernet
connection has been made, a solid green LED (Link) lights up on the amplier's RJ-45 Ethernet port. If there is no green LED
showing, there is either a problem with the cable or the network source which must be addressed before proceeding further. All
RJ-45 Ethernet ports ash green when active, so backtrack through any other cables, routers, or switches to nd the problem.
The ashing yellow LED (Data) indicates that data is owing to or from the amplier.

 9 PROTEAne SOFTWARE
9.1 Installing and Using the Software
Ashly Proteane software is included on a CD
with each unit, and is also available on the
Ashly website. After installing the software
and starting the program, the startup screen
will appear as shown to the right, with Ashly
Network Tree, Project Canvas, and Menu
items described below:
9.1a Ashly Network Tree - The Ashly
Network device tree on the left side of the
software start-up screen is an accurate reec-
tion of all Ashly devices currently installed
on available networks. A green device name
means it is a live device, a red device name
means it was previously installed but is now
off-line, and a yellow device name means it
is live but congured incorrectly. All Ashly
devices broadcast their availability to the
software when they start up. The user can also
manually scan for devices with <Scan For
Devices> found below the network device tree.
Devices can be dragged from the device tree
and placed onto the project canvas as icons to simulate rack installation groups, or be added as virtual devices using the [Add
Item] menu command with [Design Mode] checked On. Editing a device can be done from either the device tree or from it's
representative icon on the canvas. All software changes made to a live device are executed in real time.
The software automatically detects and displays controls for any installed device options. DSP, CobraNet, Dante, and AES3 are
currently available, AVB network audio will be available in the future.
Note: The user can nd and verify a live device on the network by right clicking over the unit’s name or icon, and then click
<Identify> which will ash the device's Com LED for two seconds.
9.1b Ashly Project Canvas - The project canvas is used to represent a sound system installation as a visual project. Networked
devices can be dragged from the Network Tree onto the canvas and congured. Virtual devices can be added to the canvas
as well, congured, and later assigned to a live device (see section 9.1f). Live networked devices appear with a green border,
off-line network devices have a red border, and virtual devices appear without any border. The primary canvas is always called
"Ashly Project", but additional project les can be saved under different names.
Additional visual control objects such as level faders, LEDs, meter bars, preset, standby, mute, and source select buttons can be
placed on the canvas and assigned to control a specic parameter on one or more devices in the project. Use [Add Item>Control
Objects>(object)] to place a control object on the canvas, then double-click or right-click to edit its properties. Use [Add
Item>Display Objects>] to place an image or text on the canvas. Additional drawing tools are found in the upper left corner
above the canvas and include lines and rectangles. The user can alternately right click anywhere on open canvas to add items.
Checking <Design Mode> allows placed objects to be moved around, while unchecking <Design Mode> locks objects in place.

stand-alone control objects and their settings, as well as drawn or linked graphical objects placed on the project canvas.
[File>Open Project] - opens a project le (*.cpj) from the computer
[File>Save Project] - saves all data on the project canvas, and can additionally save all presets on devices in the project
[File>New Project] - clears the canvas, clears all data, and clears all project tabs other than the "Ashly Project" tab
[File>Print Setup] - This determines the target printer for an individual device's parameter settings report, available by right-
clicking on any live device in the device network tree. All current device settings are written into the printable report.
[File>Warnings] - These three software warning messages can be turned off; <DSP Channel Disable>, <Sampling Frequency
Change>, and <DSP Full>. Ashly recommends leaving all three warning messagess turned on.
[File>Log] - The Log Control allows the user to adjust what parameters are logged to the Ashly Event Logger, which maintain
a log of all changes made to a Proteane System while Proteane Software is running. For most users this is not important; however,
this does allow a user to know what has happened in the past to the system. The Event Logger uses the Windows Event Handling
System to log events, which can be viewed and cleared using the Windows Event Logger (Start>Control Panel>Administrative
Tools>Event Viewer>Protea NE Software).
9.1d Network Menu
[Network>Scan For Devices] - This command looks on the local network (using the broadcast address) for any Ashly network
enabled device. Any devices it nds will be added to the network device tree. This scan is done automatically when the software
is started. A button of the same name and function is also found beneath the network device tree.
[Network>Network Cong] - Adjusts the metering refresh rate, server retries, server timeout, and heartbeat timer.
9.1e Project Menu
[Project>Tab Page>Add, Remove, Rename, and Clear] - Multiple project tabs can be used within the same project to represent
different racks, rooms, buildings, etc, and are managed using these four commands.
[Project>Save/Recall Preset To/From All Devices] - This is used to save or recall all device parameters in the current project,
based on preset number. When using <Save Preset to All Devices>, a unique preset le is created for each device and saved to
the same preset number across all devices, overwriting the current preset parameters for that number. When using <Recall Preset
From All Devices>, the chosen preset number will be recalled from each device.
9.1f Add Item Menu
[Add Item>Design Mode] - With Design Mode checked On, virtual Ashly devices can be placed on the canvas and congured
before connecting to the live network devices they will control. This way, a complete system installation can be set up ahead of
time in software and saved as a project to be applied later. To apply the prepared project le, use the following steps:
1) Connect all Ashly devices to the network and launch the software, verifying that all devices appear green in the network device tree.
2) Open the project le and link one device at a time by dragging each network device from the device tree onto its virtual
device icon represented on the canvas. You will be prompted by the message <Copy all settings from canvas device to online
device?>, after which all virtual device settings will be applied to the live networked device. A live device icon on the canvas
is indicated by a green surrounding box, whereas a virtual device has no green surrounding box.
With Design Mode unchecked, all device icons, control objects, and display objects on the canvas are locked in place.

the instructions.
9.1i Load Analysis Menu - Load Analysis is a software tool used to visualize the swept AC impedance of a given loudspeaker,
and to test the integrity of a potentially damaged loudspeaker or connection. Load impedance analysis works by formulation of
speaker output measurements taken when a user dened swept sine wave input is applied to one amplier channel by software.
Currently, the only Ashly ampliers with load analysis are NE two-channel (dsp) and nXp.
Loudspeakers are specied with a nominal impedance rating, 8 Ohms for example. This is an average rating, the actual imped-
ance across it's frequency range can vary substantially above or below 8 Ohms due to inductance, resonance, and other proper-
ties which affect impedance . Lower impedance, even within a narrow frequency range, can increase the amount of amplier
current delivered to the speaker. This can present a problem when wiring multiple speakers in parallel, as the combined speaker
impedance may become so low that it causes the amplier to go into overcurrent protection mode and shut down. The way to
avoid this is to pay attention to the lowest measured impedance rather than the nominal impedance rating for a given speaker
load, and make sure the amplier is rated to drive that load.
A second function of load analysis is for troubleshooting loudspeakers. When loudspeakers are damaged by overheated voice
coils, torn cones or surrounds, mechanical damage from being dropped, or have corroded connections, they can exhibit different
load impedance characteristics than when new. An initial load impedance analysis can be performed when the system is rst
installed and the results saved to disk for reference. Future load impedance tests can be compared to the original reference data
and issue a pass/fail rating based on a user-dened percentage of similarity to the original data. Load anaylsis can thus help
determine if loudspeakers are damaged or disconnected, and can be administered from a remote network location.
Keep in mind that this test is a real time audible event, so be certain that all test parameters, particularly volume (sweep level)
and frequency range (sweep start/sweep stop), are suited for the speakers under test, and that the venue is ready for a brief
period of test tones at potentially signicant volume. Note: During the test, all audio DSP processing in the amplier is stopped.

[Load Analysis>Launch Load Analysis] - This is the working window for performing a load analysis. The user must rst
select an available networked amplier from the <Analysis-Capable Amplier> device tree, then select the output channel to
test, then apply the appropriate test settings.
Warning: Do not send low frequency test tones to high
frequency drivers or use excessive sweep level, always be
certain that the swept frequency range and output level is
within the safe operating range of the speaker under test.
Remember that all DSP functions are disabled, including
crossover lters and limiters. A sweep level setting of 1V
will produce a relatively quiet test tone into any speaker,
however load impedance characteristics can change at higher
volume levels, so test accordingly but carefully. Make sure
the Sweep Level and Sweep Start Frequency are
properly set for this loudspeaker before running the
test! Click on <Test Amplier> and a series of tones will
be heard through the loudspeaker under test. The test can be
immediately cancelled by pressing the same button again.
When the test is nished, a plotted curve (yellow) shows
load impedance vs. frequency. Click <Set Ref.> to establish
this curve as a reference (red) baseline, or save the data to
disk for future tests.
Note: Running the load analysis tool when there is no speaker
connected to the amplier is useful for learning about the
procedure, but provides no meaningful data.

9.2 nX Device Options Menu
Double-click on a nX amplier in the Network tree or on the canvas.
9.2a Flash Reprogram Mode - A nX amplier can be ash reprogrammed by download-
ing a new program le (rmware) to the amplier over the network. Latest rmware updates,
if available, can be found on the Ashly website. When the amplier is put into ash reprogram
mode, all audio functions are suspended, the power switch LED ashes, and the COM LED
remains lit until ash reprogram is completed. Flash Reprogram only appears in the device op-
tions menu when a live device is connected.
9.2b Link Group Conguration - Link groups allow DSP functions of the same type to
track each other across channels within a device. For example, if two separate EQ controls
on different channels are linked, any change made to either one of the equalizers will result
in an identical change to the other.
nX ampliers support up to 16 Link Groups, and every DSP tool can be assigned to one of these groups. Once assigned to a
group, all similar DSP functions within that group will track parameter changes with each other. More than one type of DSP
function block can be assigned to the same group. Each link group can be assigned a name by the user, and can also be assigned
a color for easy identication. For further details about linking, see the online help in Proteane software.

Operating Manual - nX, nXe, and nXp Power Ampliers
9.2c Power On Delay - Use this feature to delay the amplier turning on when rst powered up or when waking from sleep.
Delay is measured in increments of 100mS, with the limit at 25.5 seconds. The power amplier should be the last device to power
up after other system components have turned on and stabilized. Multiple ampliers on the same circuit breaker should have stag-
gered Power-On Delays to avoid excessive in-rush current which can trip the breaker.
9.2d Idle Time Before Sleep - On nXe and nXp series ampliers, the sleep clock timer can be set from 0 to 120 minutes
9.2f Factory Installed Options (not shown) - Factory installed options currently include AES3, CobraNet, or Dante. Options
are auto-detected on live ampliers, but can be added to virtual ampliers when working in Design Mode.
9.2g Clear All Stored Presets - nXe and nXp only.
9.2h Sample Rate and Master Clock Source Selection: Changes to both of these settings can be made by clicking the <Show
Advanced Control> box in this menu item. Sample rate can be set to either 48kHz or 96kHz. Note that at 96kHz, the DSP usage
doubles, resulting in half the available processing power for lters, delay, limiting, etc. Also note that the Feedback Suppressor
cannot be used at 96kHz sample rate. Factory default settings are Auto Selection for clock source and 48kHz sample rate.
9.2i DVCA Control - This feature is used in conjunction with the DSP tab gain tool called <Gain w/VCA>. Use this feature
to create up to four gain subgroups as you would on a mixing console. Any input or output channel can be added to one or more
VCA subgroups for group gain control. While no external hardware control is allowed for this subgroup, a level fader control
object can be added to the project canvas and linked to this named VCA level control.
9.2j DSP Enable/Disable - This removes from operation the input, output, or matrix mixer DSP functions on any channel.
When removed, audio is passed directly through the stage that has been disabled.
9.3 nX Preset Options Menu
The Preset Options menu in the main device window allows user-dened setups to be named, saved
to, and recalled from the amplier or a networked computer. Several other utility functions are avail-
able as well. Presets are a snapshot of all current settings on a given amplier.
nX ampliers can store up to 31 internal presets, each preset storing control data for all channels
and audio functions. Preset names must be 20 characters or less. Changes to an individual preset
can be saved to the amplier using <Save Preset To "nX***">, or saved to the PC using <Save
PresetTo Disk>. Individual preset les use the extension (*.pne).
9.3a Sub Presets: Instead of saving or recalling an entire preset affecting all device func-
tions, a sub-preset affecting only a user dened sub-set of DSP functions can be created. To
create a sub-preset, rst check the box labeled <Selected for Sub-Presets> in all DSP control
blocks to be associated with this sub preset, then under the preset options menu click <Save
Sub Preset to Disk> or <Save Sub Preset to "nX***" >.
A preset or sub preset can be loaded to the amplier by one of the following methods:
1) Use Proteane software on a PC connected to the network to recall les saved on either
the PC or on the amplier.
2) Use contact closures to load presets 1-4 from memory by wiring switches to the rear panel
contact closure connector.
3) Use an Ashly WR-5 or neWR-5 remote control.
4) Use the event scheduler.
Note: A full preset recall event will overwrite any unsaved changes, so be sure the current conguration is saved before continuing
or any changes will be lost. The amplier always loads the last working settings on power-up, to preserve any changes should
the power be inadvertently turned off prior to saving a preset. Caution: A new preset may have dramatically different settings
capable of damaging sound system components, so be careful not to recall the wrong preset while the system is on.
