Operating Manual - NE Multi Channel Power Amplier
The basic NE multichannel ampliers come in either four channel or eight channel congurations with Euroblock input and output
connectors. Standard features on all models include balanced inputs, bridge mono mode, and Ethernet control using Proteane
software. Remote control functions include standby, contact closure preset recall, and DC level control. Programmable remotes
for NE ampliers with DSP include Ashly’s WR-5 or neWR-5 button controllers, RD-8C or FR-8/16 fader controllers, third
party RS-232 control, or Ashly Remote app for iPad®.
Factory Installed Options
Factory installed hardware options for NE multichannel power ampliers include the following:
1) Internal DSP - With Protea DSP installed, each input channel benets from pluggable DSP blocks for dynamics control, gain
functions, graphic and/or parametric EQ, Hi-pass/Lo-pass lters, time delay, metering, and test signal generator. A mixer section
with assignable routing allows any input to drive any or all amplier outputs. Output channels have the same DSP functions as
inputs, with the addition of automated crossover setup and FIR lter capability. Both inputs and outputs can copy/paste their
settings to other channels, or can link with one or more other channels to track their settings.
Presets store and retrieve parameters of an entire amplier control surface and DSP settings. In addition, Sub Presets allow for
a collection of individual DSP parameters within and across multiple channels of an amplier to be stored and recalled as a
set, affecting only those parameters and channels which have been tagged. Up to 35 presets/subpresets can be stored within the
amplier and can be recalled in real time from a computer, by a programmable remote control, or by on-board contact closure
switch connections on the back panel.
2) AES3 Input - With a four or eight channel AES3 option installed, AES3 outputs can plug directly into the amplier. Using
AES3, 2 channels of digital audio are sent over a single mic cable, maintaining a completely digital signal path until just before the
power amplication stage. 48kHz & 96kHz data rates are supported. AES3 can be installed with or without DSP.
3) Network Audio - Dante® or CobraNet® network audio modules can be factory installed, with or without installed DSP. Note
that ampliers without DSP must have a factory installed OPDAC4 module to use network audio.
Dante®, created by Audinate, is an Ethernet based digital AV network technology that uses existing 100MB or 1GB network
infrastructure for delivery of high performance, high channel count audio signals. Ashly products with network audio capability
can be integrated into a Dante™ digital audio system by purchasing our OPTDante module as a factory installed option, and
controlled using Proteane software.
CobraNet® is a technology developed and supported by Cirrus Logic (www.cirrus.com). It is a combination of software, hard-
ware and network protocol which allows distribution of multiple channels of real-time, high quality digital audio over a standard
Ethernet Network. For detailed information about CobraNet or its implementation or installation please visit www.cobranet.info.
Protection
NE multichannel ampliers use the following protection schemes:
Over Current Protection - Is controlled in the output stage.
Thermal Protection - The amplier senses output device temperature and adjusts a two-speed fan to keep the operating tem-
perature within acceptable limits. If device temperatures exceed that limit, the input to that channel is rst reduced, and as a last
resort the power supply will be switched off while the fan continues to run.
Mains Protections – Protection within the power supply includes: Inrush Current Limitation during power up, Mains Over
Voltage Detection, and internal Mains Fuse Protection. To protect the Mains fuse against AC overcurrent due to excessive au-
dio output current, there is also a protection scheme indicated on the amplier front panel and software control surface which
reduces audio output level until the overcurrent condition is no longer present.

10. Remote Level Control - These pins are wired to potentiometers such as the WR-1 for level control of individual channels
11. AC Inlet - Used for the detachable AC cord supplied with the amplier.
WARNING: Do not remove or lift the mains connector ground pin.
Installation
Before connecting to mains power, make sure that the switches and wiring are all set to the conguration needed for your par-
ticular application. Failure to do so could result in damage to the unit or to other components in your system.
CAUTION: Before mounting or connecting the amplier, always disconnect it from AC. Use four screws with lockwashers
when mounting the amplier to the front rack rails. Rear support is also recommended, especially for mobile or touring use. To
reduce the risk of re or electric shock, do not expose this apparatus to rain or moisture.
Requirements
NE multichannel ampliers have specic physical, electrical and signal requirements for proper operation. These requirements
will vary depending on your specic application, setup, and settings on the amplier. When setting up and testing your system,
please take special care to double check all connections and settings. Refer to the specications section of this manual for spe-
cic input, output and other gures.
Constant Voltage Models (25V, 70V, and 100V) and High Pass Filters
Ampliers that are factory congured as constant voltage models (25V, 70V, or 100V) come standard with High Pass Filter (HPF)
hardware installed, allowing for software selectable 80Hz or 400Hz lters on each channel. High pass lters prevent low frequency
energy from saturating the iron core of low cost speaker tap transformers typically used in distributed constant voltage systems. Available
lters are 80Hz @12dB/oct, 400Hz @ 6dB/oct, and OFF. The 400Hz setting is commonly used in paging systems with horn speakers.
Note that with just the standard HPF hardware installed, DSP, network audio, or AES3 input are unavailable.
NE ampliers shipped with AES3 or network audio, but without DSP, also come with an Ashly OpDAC A/D converter card installed.
This OpDAC converter card offers the same software controlled HPF options as the standard amp.
Note: Constant voltage ampliers that ship with Protea DSP do not have the standard 80Hz/400Hz HPF circuitry installed, and as
such must have High Pass lters manually set in the software DSP section.

4. REMOTE AMPLIFIER CONTROL
ON/OFF/Remote Standby
The NE multichannel ampliers have three possible states, OFF, ON, and STANDBY, each with a status LED on the front panel.
Control for these three states is managed by the following:
1) Power Switch - When the power switch is turned off the amplier is completely off, UNLESS the power switch has been
disabled from software, in which case the power switch on the amplier has no effect at all. If the power switch has been dis-
abled, the front panel DISABLE LED will be lit. Even if the AC power is removed, the amplier’s internal memory will retain
the <power switch disabled> status until changed again from software. Performing a factory reset will clear and restore all
internal amplier memory to original factory settings.
2) Remote Standby Contact Closure - When these two pins are wired to a switch and connected
closed, the amp will go into standby mode, whereby the amp is active but in a reduced power state.
For remote standby to work, the power switch must be turned on or on but disabled in software.
3) Software On/Standby - On/standby in software functions the same as the remote standby
contact closure on the back panel. Clicking on STANDBY places the amp into standby mode.
Software on/standby does not override the hardware Remote Standby, they both remain active.
4) Software Power Switch Enable/Disable - This feature disables the front panel power switch. If the power switch is disabled
from software, the front panel DISABLE LED is lit. The power switch remains disabled until enabled again from software, even
after the amp is unplugged from AC.
Preset Recall
The preset recall connections on the back panel allow different presets to be loaded from amplier memory when one of the
contacts is closed to the provided ground pin. Device presets are congured from software and can include gain settings, mute
status, polarity, and DSP functions if the amp has DSP installed.
The NE amplier stores up to 35 internal device presets. A device preset stores the most commonly used control data for that
amplier. A device preset (saved to amplier) differs from a computer preset le in that a computer preset le stores all infor-
mation associated with the amplier and its software settings, while the device preset only stores the most commonly used and
relevant audio settings. Changes to an individual preset can be saved to the amplier in software using <Preset Options/Save
Preset To Device>, or saved to a PC using <Preset Options/Save Preset To File>. Sub Presets (collections of DSP parameters
individually selected from software) are saved in a similar fashion. Individual preset les use the extension (*.pne).
Loading a preset can be done using software, using preset recall contact closure connections on the back panel, using an Ashly
programmable remote button controller, or using the Ashly Remote iPad® app. Contact closure pins P1 through P4 load device
presets 1-4 from the amplier memory.
Caution: A new preset may have dramatically different settings capable of damaging sound system components. Be careful not
to recall the wrong preset while the system is on.
Data Control
The data euroblock on the back of the amplier is used for connecting an Ashly WR-5 programmable zone controller or RD-8C
remote level controller. The data interface provides data and phantom power for these devices using four conductor bell wire.

Operating Manual - NE Multi Channel Power Amplier
WR-1 Remote Level Control - The WR-1 is a dual potentiometer remote volume control designed to mount in a standard single
US electrical wall box, and is wired to the amplier back panel Euroblock connector labeled “Remote Level Control” using four
conductor wire. Installed DSP is not required for WR-1 remote level control. If wiring a custom potentiometer assembly other than
the WR-1, connect +5V from the Remote Level Control Euroblock connector to the potentiometer’s CW pin, GND to the CCW
pin, and the channel under control to the wiper. Do not connect the WR-1 remote level control ground to any other external grounds.
WR-2 Remote Preset Recall Switches - The WR-2 (shown
at right) allows selection of one of four presets via interlocking
pushbutton switches. Each pushbutton switch can be connected to
a Preset Recall Pin on the back panel of the amplier. The termi-
nal numbers correspond to the rst 4 device presets stored in the
amplier. Pressing any button will select the corresponding preset.
Windows are provided by each switch for a user-generated label.
WR-1.5 Remote Level Control and Preset Recall Switch - The WR-1.5 (shown at left) combines
one potentiometer for remote level control with a four position rotary switch for preset recall.

RD-8C or RW-8C Remote Level Control -The RD-8C and
RW-8C are remote level controllers which are connected to the
amplier’s Data Port, and are phantom powered from the ampli-
er. They can only be used in NE ampliers which have DSP
installed, and are used in conjunction with the “Remote Gain”
pluggable DSP tool placed in an input or output in software.
Maximum cable length is 1000 ft using #24 gauge twisted pair.
The RD-8C is a desktop controller, while the RW-8C is elec-
tronically the same but mounts as a wall plate using a standard
North American 4-gang electrical box and connects using a
Euroblock.. There are eight channels and a master, each with a
fader control and an on/off button. Note: Only one RD-8C can
be used per amplier, and use of an RD-8C will exclude the use
of the data port for a WR-5. One or the other remote control
device may be connected, but not both
WR-5 Programmable Button Control-
ler - The WR-5 is a programmable button
remote control which mounts into a standard
US electrical wall box and connects to an
amplifier data port using four conductor
wire. Maximum cable length is 1000 ft using
#24 gauge twisted pair. A decora cover plate
(not included) can be purchased at hardware
stores to cover the WR-5 electrical box and
satisfy the aesthetic needs of the installation.
The WR-5 is phantom powered from the
amplier. Up to four different WR-5 remotes
can be phantom powered from one amplifer,
and more can be added by purchasing an
Ashly RPS-18 remote power supply.
WR-5 buttons are programmed from software, after the WR-5 is wired to an amplier and assigned a unique ID number in the
WR-5 device window associated with that amplier in software. Each WR-5 button has a status LED. Standard control functions
include preset recall/scroll and mute, and in ampliers with DSP installed the functions also include gain control, zone source
selection, individual channel and matrix point level control. Note: To use the WR-5 as a remote level control, a (ne)WR-5 Remote
Gain tool must be placed in one of the DSP processing blocks of the channels(s) to be controlled. A windowed mylar pocket is
available to insert custom button labels. A WR-5 label template is available on the Ashly web site.
INA-1 Inline RS-232 Adapter (not shown) - The amplier Data Port uses a proprietary serial communications protocol which
can be converted to RS-232 by purchasing the Ashly INA-1 RS-232 adapter. This allows the use of custom designed third party
RS-232 controllers.

Operating Manual - NE Multi Channel Power Amplier
neWR-5 Networked Programmable Button Controller - The neWR-5 remote control is a networked version of the WR-5, us-
ing Ethernet instead of the data port to communicate with the amplier. Connecting and powering the neWR-5 is done using Cat-5
Ethernet cable and a Class 1 IEEE 802.3af Power over Ethernet (PoE) switch, hub, or in-line PoE injector. If PoE is unavailable,
the Ashly RPS-18 (sold separately) is a 15-48VDC power supply capable of at least 2 watts per neWR-5 and can be hard wired to
the back of the neWR-5. PoE current draw is 38mA @48VDC and 80mA@15VDC. A decora cover plate (not included) can be
purchased at hardware stores to cover the neWR-5 electrical box and satisfy the aesthetic needs of the installation.
The neWR-5 appears in the software device menu tree and must be assigned within it’s device window to a specic amplier. The
neWR-5 has six programmable function buttons which can light up green, red, or amber to display status. Further information on
LED status is found in the neWR-5 owner’s manual, available on the Ashly website. To the right of the function buttons is a pocket
in the mylar overlay for a printed function label to be inserted, also available as a template on the website. The two other buttons
are used to adjust function parameters such as gain or preset number, and are indicated by the LED display. Without DSP installed
in the amplier, neWR-5 functions are limited to preset recall and mute. Note: To use the neWR-5 as a remote level control, a (ne)
WR-5 Remote Gain tool must be placed in one of the DSP processing blocks of the channels(s).
There is also a hard-wired Lock-Out feature on the neWR-5, where the closing
of a switch wired to the lockout Euroblock renders all buttons inactive.
FR-8 and FR-16 Networked Fader Controller - The FR-8 (shown at right)
and FR-16 are Ethernet based remote fader control units, with the ability to
assign each fader control of one or more input or output DSP gain stages or
level control for a DSP matrix mixer point. The button LEDs for each fader
are normally used to indicate as-
signable signal level/clip or mute
status, but can alternately select A/B signal source for that fader. The FR remotes can
be wall mounted to electrical box, panel mounted, or freestanding, and have a back
panel contact closure for full front panel lockout. See further details in the FR-8/16
owner’s manual on the Ashly website.
Ashly Remote App for iPad® - A custom and secure touch-screen control surface
for the iPad® can be designed using the <Ashly Remote> application, available free on
iTunes® or via the Ashly website. Controls, labels, and images are combined to manage
key amplier functions over a wireles network connection.

5. PROTEAne SOFTWARE
A software CD-ROM is no longer included with new ampliers. Proteane software is available for free download from the Ashly
Website, offering a comprehensive suite of tools for controlling Ashly NE multichannel ampliers. The standard ampliers
allow for Ethernet control and monitoring of power functions, mute, and preset control. With the DSP option installed, software
control and monitoring of audio functions can be custom congured on a per channel basis, as well as through linked channels.
More in depth discussion of software features can be found in the Proteane software online help.
The base amplier interface includes a main control surface, password protected security functions, and network property
management. Link Group Conguration and Power On Delay* can be set up under the Device Options menu tab. In addition,
provisions for implementing DSP functions, AES/EBU Inputs, and network audio inputs are available, presuming the necessary
hardware options have been installed in the amplier. Proteane software will auto-detect any installed hardware options and
display the resulting menu items once it recognizes the amplier on the network.
*Note - Power On Delay does not work when standby mode is activated via contact closure.
Link Group Conguration - Linking allows the controls for multiple DSP function blocks to track each other. For example, if
two different graphic equalizer blocks are assigned to a link group, any change made to a control within either of the equalizers
will result in an identical change to the other. Blocks may be linked across channels.
Each device will support up to 16 link groups. DSP function blocks can be individually assigned to these link groups. Once
assigned to a group, all similar functions within that group will track parameter changes. More than one function type may be
assigned to a 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 software online help.
Preset Options - The preset options menu allows amplier setups to be saved to or recalled from an amplier or a computer. File
presets are the complete amplier and software settings, whereas device presets are limited to commonly used functions.
Sub Presets - Sub Presets are user dened groups of DSP functions within one channel or across multiple channels. Sub Presets
allow the user to instantly recall a pre-determined set of DSP parameters to quickly address changing environmental conditions,
without the risk of making undesirable or irrecoverable system changes.
The Amplier Control Surface Tab
The control surface tab is the main software interface for the amplier. Key features of this window include:
1) Channel and Offset Link Group Faders - The main level control provides up to 40dB of analog input attenuation. More than
40dB of cumulative attenuation causes the channel to mute. If a channel has been assigned to an offset link group, a colored
triangular marker appears on the left side of the fader graticule for secondary level control of all channels in that group. The
main level control faders can not be linked to a group.
2) Mute button - This mutes the input channel
3) Polarity button - This inverts the phase of the input channel
4) Offset link group - Up to 16 groups are available for the purpose of linking similar function parameters across multiple chan-
nels. In addition to the control surface secondary level control (not the main fader), most DSP functions have a link group check
box in their work window to assign a specic parameter to one of the eight link groups if desired. Link groups can be renamed
by clicking on any group name and entering the new name then pressing <enter> on the keyboard.
5) Attenuators - These two dials indicate the physical position of hardware controls on either the amp front panel or remote
DC level control (if present). Note that these will display the position of attenuators even when they are disabled by software.
6) Total Attenuation - This indicates the total amount of attenuation being applied to the channel. This is the sum of the follow-
ing attenuators: main fader, offset link group attenuation, front panel and remote attenuators.
7) Meters - Input and Output meters display the real time activity per channel, in dB below rated output. Also, the amplier’s
operating temperature and output current are shown. Output current shows that the amplier channel is actually delivering
output to a connected speaker load.

The Amplier DSP Tab
If the amplier has DSP installed, the DSP tab automatically appears. The DSP tab includes an input side and an output side,
with a cross linking matrix mixer in between. Key features of the DSP window include:
Input Channel Number - Right click on this to bring up Clear, Copy/Paste, Link, and Sub Preset for that input channel.
Input Channel Name - The user can name each input channel.
Input Mute Button - Mutes the input.
Pluggable DSP Tools - Six blocks are available on both inputs and outputs for custom conguration of pluggable DSP
processing blocks. Total DSP usage for the four input and output channel groups is indicated as a percentage at the bottom of
each input section in the DSP tab. Increasing the number and complexity of applied DSP tools increases the DSP usage. Note:
The total DSP usage per group of four channels is limited, and cannot exceed 100%. Available DSP tools include:
1) Dynamics controls - Brick Wall Limiter, Compressor, Autoleveler, Ducker, Noise Gate
2) Gain functions - Gain, Gain with VCA, Remote Gain, (ne)WR-5 Remote Gain
3) Equalization - 31 band Graphic Equalizer, 10/6/4/2 Band Parametric Equalizers, FIR lter (outputs only)
4) Crossover functions - Four Way, Three Way, and Two Way Crossovers are available on outputs only.
HPF and LPF lters are available on both inputs and outputs.
5) Delay - Speaker Delay at 48kHz sampling rate is 21mS, and Delay is 682mS. At 96kHz, 10.6mS and 341ms.
6) Metering - -60dBu to +20dBu display
7) Signal Generator - Pink noise, White Noise, Sine Wave from 20Hz to 12kHz.
Extensive online help information is available for all DSP blocks within the software. From within any DSP tool, simply press
<F1> on the keyboard for online help for that tool. Also look in the Proteane Software Help Menu/Contents and Index/Contents/
Protea NE Products/PE Multichannel Ampliers/DSP Control for details of all DSP functions.
Input/Output Matrix Router - Any input can be routed to any or all outputs. Click and drag from the input to output to
assign routing. For faster routing of a single input or output to multiple channels, highlight its node and then press Ctrl+Click
over the desired nodes to connect to. To delete a route or clear the matrix, right click on the routing line or node. Also, right
click anywhere in the matrix area to bring up a menu of common routing choices.
Output Mute Button - Mutes the output.
Output Channel Name - The user can name each output channel.
Output Channel Number - Right click on this to bring up Clear, Copy, Link, and Sub Preset functions for that output.
