Page 4/13

ALLDSP ASP-4M8
1.2.2. Power Switch
The Power Switch turns the ASP-4M8 on and off. As with all professional audio installations, power amplifier
should be turned on last when powering up and must be turned off first when powering down.
1.2.3. Ethernet Connector
This RJ-45 connector is used to connect your product to a network. It can then be configured and controlled
in real time with our PC and MAC configuration program, or with our iPad / iPhone control software (available
on the Apple App Store). From the PC or MAC you can also update your processor to the latest firmware.
Please check our website regularly for updates.
1.2.4. Analog inputs
The analog input section of the ASP-4M8 offers four electronically balanced XLR connectors. The input level
is +23dBu max, electronically balanced.
1.2.5. AES3 Inputs
The digital input of the ASP-4M8 offers two input channels on one electronically balanced XLR connector.
The input will accept AES3 input signals at 44.1, 48, 88.2, or 96kHz. An internal asynchronous sample rate
converter (ASRC) converts the sample rate to the ASP-4M8's native sample rate, thus preserving the highest
possible processing quality even when running off a 44.1kHz digital signal.
1.2.6. DANTE Inputs
The ASP-4M8 offers two Dante input channels. No separate connector is needed; the ASP-4M8 uses one
Ethernet connection for Dante signals and Command & Control signals. The processor will accept sample
rates of 44.1, 48, 88.2, and 96kHz. The Dante inputs can be configured though Audinate's Dante Controller
Software. An internal asynchronous sample rate converter (ASRC) converts the sample rate to the
ASP-4M8's native sample rate, thus preserving the highest possible processing quality even when running off
a 44.1kHz digital signal.

2. Getting Started
2.1. Quick Start
For those of you that wish to jump right in, the following information has been provided to act as a quick start
guide for optimizing performance of your processor.
2.2. Connections
When setting up your processor, make connections as follows:
2.2.1. Signal Connections
- Always make connections prior to applying power to the processor.
- Connect the output(s) from the sending device (mixer) to the Ch. 1 XLR input connector (mono) or both, Ch.
1 and Ch. 2 XLR input connectors (stereo).
- Make output connections from the output XLR connector(s) to the input connector(s) of the selected power
amplifier(s).
Always make sure that your power amps are the last item turned on and the first turned off.
Once all of the connections have been made, and the processor is powered up, you can navigate through the
entire signal path of your processor from the front panel. The display provides you with a clear and concise
overview of each aspect of the signal path from the input (left side of display) to the output section (right side
of display).
2.2.2. Remote Monitoring and Control
For the quickest and easiest results we recommend to install and use our freely available iPad, iPhone, PC or
MAC configuration software. It provides a complete and comprehensive tool to make your loudspeaker
configuration settings, and to manage your presets.
When connecting the ASP-4M8 via an Ethernet network, you have several options. The PC/MAC application
has an auto-discovery tool that will automatically connect to any unit found on the network.
Please refer to the Software Manual available on our website for details on the control software.
Note: Please make sure there is only one device (Windows PC, MAC PC or iOS device) running the ALLDSP
software at any time. The software can control as many devices simultaneously as the network can handle. In
a typical (default) DHCP configuration, this is 200 units.
2.2.2.1. Standard DHCP Network
This is the recommended connection method. For plug-and-play connection, use a standard Ethernet Router,
plug in the unit and your computer, and the connection should be made automatically. Standard routers have
a DHCP server built in and enabled. A DHCP server assigns a network address to your computer and to the
ASP-4M8, allowing them to connect automatically.
2.2.2.2. Connection without DHCP server
Alternatively, you can use a direct (cross) cable or a simple Ethernet Switch to connect the unit to your PC or
MAC. Please note that in this case, especially Windows computers running Windows XP may take up to
several minutes to assign themselves a network address (indicated by the text: "This connection has limited
or no connectivity"). The computer and the ASP-4M8 both will assign themselves a network address in the
ZeroConfig range (169.254.0.0 - 169.254.255.255), and the ASP-4M8 will be discovered automatically by the
PC/MAC application. To facilitate connections without DHCP router, it may be convenient to set your
computer to a fixed IP address. If you do this, please choose any address in the ZeroConfig range, and set
the subnet mask to 255.255.0.0.
Page 6/13

ALLDSP ASP-4M8
2.2.2.3. Fixed IP address
It is also possible to set a fixed IP address and subnet mask for the ASP-4M8. WARNING: If you set a wrong
address (in a different range than your computer), you may not be able to connect anymore. It is strongly
recommended to consult a system administrator before making such settings. It is not possible to set the IP
address via the front panel menu. If you have set a fixed IP address and subnet mask, you must set your
computer to an address within the same subnet. To verify this, you can read out the IP address via the local
LCD display: Press "Menu" 4 times, then press the rotary encoder until the IP address and subnet mask
appear.
2.2.2.4. Firewall
After starting the software application for the first time, your computer may ask you to allow or block the
application access to the network. Please make sure to allow this; if there is a firewall between the application
and the ASP-4M8, the application will not find the ASP-4M8.
2.3. System Setup and Gain Structure
This product offers a wide range of tools for sound system design and setup. These tools can make your
system more efficient and better sounding, but to get the best possible sound it is important to use these tools
properly.
The following section explains how to maximize system gain and how to use the limiters to protect your
amplifiers from clipping. In traditional system design, the output of your console would be routed to a system
EQ, a compressor, and a crossover with output level control. From the crossover, there may be additional
filters that are employed to improve the response of your speakers. There may also be limiters set up to keep
your amplifiers from going into clipping and protect your speakers from the hazards of a clipped signal. Your
amplifiers play a vital role in system setup, because they are last item in the chain before your speakers and
offer the greatest amount of gain (that is their job after all). If your limiters and amplifiers are incorrectly setup
you will not be using your system to its fullest potential and could be harming your speakers.
To ensure an optimal gain structure:
Play a signal at the nominal level from your mixing desk, and set the input gain of your processor to 0.
Set the crossovers that you want to use, while keeping the output gains also at 0.
With DISCONNECTED loudspeakers, turn up the volume of the power amplifiers entirely clockwise (full
volume).
Now reduce the output gain and / or the output limiter setting to get the desired gain, so that the amplifier is
just clipping and the built-in limiters of your processor are just limiting. If the amplifier does not have a built-in
Peak limiter, set your processor's limiter so that the amplifier does not clip.
Now turn down the volume of the power amplifiers, connect your speakers, and slowly increase the volume
while checking the sound.
If all is well, there should be distortion-free sound, and the limiter LEDs are flashing or off, but not
continuously on. If they are continuously on, reduce the output gain of your processor.
If you can not reach enough signal level, increase the processor's input gain or turn up the level from your
mixing desk.

3. Setup And Operation
Before plugging the processor in, always make sure that the power supply matches the product specification
voltage. Install this device on a flat, stable surface, not bent or curved. Do not supply power before all
components of the system are set up and connected properly. Make sure your power amplifiers are switched
on last in order to avoid transients, which could damage your speakers or annoy your audience.
3.1. System Check
After connecting all cables, you should mute all outputs first or turn the gain/level setting on your amplifiers to
minimum. Activate the HF-outputs first. In case of wrong cabling, High Frequency (HF) audio signals will
come out of bass-speakers that cannot be harmed this way. Vice versa, the Low Frequency (LF) audio
signals would destroy your HF-speakers. It is advisable to install a large capacitor in series with HF drivers
(47 - 100 uF). That way, drivers are somewhat protected against accidental instrumentation errors.
3.2. Input Setup
