1 DSP expansion module (DSP-1) for the expansion of the storage capacity and signal pro-
cessing
System expansion with analog/digital inputs or outputs
There are four slots at the rear of the N8000 which are intended to expand the systems with
analogue or digital inputs or outputs. These slots have the marking AUDIO SLOT 1 to AUDIO
SLOT 4 (see the figure on page 12). Any combination of the following types of expansion cards
can be installed:
AI-1 with 8 analog inputs
MI-1 with 8 microphone inputs
DI-1 with 8 digital inputs
AO-1 with 8 analog outputs
You can choose any slot for the installation of the expansion cards as the slot is automatically
detected by the N8000 after the installation.
System expansion with a network module
An audio network interface for CobraNet™ can be installed in the network module slot on the
rear panel of the N8000. The CM-1 module that is used for this purpose has two Ethernet
connections (Primary and Secondary) so a redundant network can be established. Up to 32
digital audio input signals and 32 digital audio output signals can be transmitted simultaneously.
Expansion of the DSP performance of the system
The N8000 system controller has efficient DSP modules with a total computing power of
300 MIPS and a working memory for a maximum delay of 21.8 seconds. If this does not meet the
requirements of your application, the processing power as well as the working memory of the
N8000 can be increased by installing the DSP-1 NetMax DSP expansion module. This allows the
execution of more complex DSP programs and the use of longer delay times or additional delay
lines.
ATTENTION: 
It is essential to switch off the N8000 if you want to install or change a module. You will
find detailed instructions in the data sheet of the corresponding module.
