Introduction
1.2 N8000 features
NetMax N8000 is an all-purpose digital audio system controller with outstanding performance
features. A high quality system design provides excellent audio quality and clear sound, which is
achieved by the application of high-end 24 Bit A/D and D/A converters with 120 dB volume
range, high-quality input and output circuits in the analog domain and digital signal processing
with optimized 48 bit double-precision algorithms. Hence, the N8000 is even particularly suitable
for demanding applications in theatres, concert halls, big churches etc.
NetMax N8000 is highly flexible due to the modular hardware design which renders many other
applications possible. Four slots with 8-channel audio modules at the rear of the device offer up
to 32 local audio channels. Each slot can be equipped either with an audio input module or an
audio output module. So, various configurations (e.g. 8-in/8-out, 8-in/16-out, 8-in/24-out, 16-in/
16-out, 24-in/8-out) can be realized in only one single device. In addition, N8000 can be
equipped with a CobraNet™ network module. Therefore, several N8000 can be integrated in a
network and be connected to a large, sophisticated system.
The signal processing in the N8000 is effected on powerful audio signal processors where,
depending on the stage of expansion, up to 8 DSPs are available. The software contains a
multitude of freely programmable signal processing components. Among other things, these are
filters with all possible characteristics, parametric and graphic equalizer, crossover network,
matrix router and matrix mixer, delays, dynamic functions, etc. Diverse configurations can be
created by combining and connecting these DSP blocks. The programming is done via the PC
software IRIS-Net. With that, you choose the desired components from a signal processing
library , place them in a working a rea on the screen and wire them to a signal flo w chart. Thus, the
resulting DSP configuration has only to be transferred to the N8000 and is ready for immediately
use.
The powerful signal processing allows complex configurations for the adjustment and control of
the sound system, depending on the application or type of event. Thus, the sonic quality of PA
speakers, monitor speakers, front fill systems as well as of the sound reinforcement of adjoining
rooms, lobbies, areas for the staff etc. can be optimized and tuned individually. In other words,
the N8000 copes with every application - even with large and complex systems - absolutely
exactly and reliably.
In addition to the audio processing, the NetMax N8000 is equipped with diverse control functions.
The scheduling with calendar function makes it possible to program one-time or recurring event s.
The recurrence can occur annually, monthly, weekly, daily, hourly or even within smaller time
intervals. Furthermore, daily programs can be set up and can also be combined to weekly
operations. With the event control, reactions to certain events or system states can be
configured, e.g. in case of overstepping or undershooting of threshold values. Faults in the
device or in the complete NetMax system are detected automatically and can be displayed on
the PC screen or transmitted to external sites if necessary.
Faults and other events are recorded in an internal log file with date and time. Furthermore, it can
be defined which types of errors or events should be recorded. The log can be read out and
displayed on the screen at any time. In the NetMax N8000 individual functions can be integrated
into complex operations. For example, several parameters can be set with various values or
states in a scene and can be changed manually or automatically at any time.

Introduction
The NetMax N8000 is equipped with all relevant interfaces by default in order to provide the
connection to the network and external components. The Ethernet port makes the connection to
existing building networks (intranet) and communication via the Internet possible. Ethernet is also
the common connection between one or more N8000s and a PC with IRIS-Net software for the
configuration, control and monitoring of a complete NetMax system. Two RS-232 serial ports can
be used in order to control the N8000 from external multi-media systems, e.g. Crestron™ or
AMX™. For that, an open interface protocol is available. The remote CAN-bus serves as
connection to Electro-Voice remote amplifiers. Up to 100 amplifiers can be attached via CAN to
one single N8000. Together with additional N8000s and amplifiers they can also be integrated in
a complex and powerful audio system. The NetMax N8000 also has a control port which offers
freely programmable control inputs and outputs. Switches, potentiometers or external control
voltages can be connected to the control inputs (GPIs). Any logic and analog functions can be
programmed. External elements which can be used to signal certain states can be attached to
the control outputs (GPOs). A PC can be connected to the USB port on the front faceplate if the
N8000 has been installed in a rack and the Ethernet port cannot be reached easily. Via the USB
interface the network parameters of the N8000 can be edited and files containing the entire
N8000 configuration can be transferred.
The highest standards regarding construction and mechanical working have been followed. The
chassis is extremely robust and, therefore, effectively protects the electronics against outside
influences. A temperature controlled fan provides thermal stability and also constant ambient
conditions inside the device. All audio interfaces are electronically balanced and have Phoenix
screw terminal connectors.
By reading this instruction manual you will get to know many additional features and functions of
the NetMax N8000. Please read on attentively and keep this manual in order to be able to
consult it at any time.

Introduction
1.4 Installation instruction
The N8000 has to be set up and installed so that both air supply and ventilation are ensured on
both sides of the device. The direction of ventilation is from left to right when you look at the front
faceplate. Devices with an opposing routing of air flow should not be installed in the same rack.
When installing the N8000 in a rack, a free air duct between the sides of the N8000 and the side
panel of the rack to the upper rack ventilation must be observed in order to ensure sufficient air
ventilation. There must be at least 100 mm free space for ventilation above the rack.
ATTENTION:
The maximum ambient air temperature of +40°C should not be exceeded in order to ensure failure-free operation.
Standard installation rails should be used when mounting an N8000 in transport racks in order to
prevent twisting of the front faceplate.
The N8000 must be protected against: dripping/splashing water, direct solar radiation, high
ambient air temperature or direct impact of heat sources, high moisture, heavy vibrations and
dust deposit.
If these conditions cannot be ensured permanently, maintenance is obligatory at regular intervals
in order to prevent any breakdowns which are mainly due to negative environmental influences.
If the N8000 is transported from a cold to a warm environment, moisture may condense at the
core. The device should not be started up before warming to the changed temperature (approx.
after 1 hour). If a solid or liquid is in the housing, cut the device off from the mains power at once
and have the device checked by an authorized service center before re-using it.
1.5 IRIS-Net
The IRIS-Net (Intelligent Remote & Integrated Supervision) PC software is used to configure and
operate the N8000 system controller. The configuration of the N8000 can be done offline (i.e.
without connection between the PC and the N8000) on the PC. After the connection between the
PC and the N8000 has been established via Ethernet, the configuration can be transmitted to it.
In addition to configurations, IRIS-Net can also be used for extensive supervision, control and
monitoring of N8000 system controllers (and Electro-Voice Precision Series Remote Amplifiers
which are connected to them).

SIGNAL / PEAK-LEDs
These LEDs serve as level meter display for input and
output signals. The SIGNAL-LED begins to flash at -25 dBU
and indicates if a signal generally exists at the input or at t he
output. The PEAK-LED flashes when the N8000 is operated
close to the level meter’s limit. The limit is approx. at
+18 dBU. The maximum level meters is +21 dBu so that
there is 3 dB of head room until the final clip limit is reached. The PEAK-LEDs should only flare
up sporadically in case of dynamic peaks. If the PEAK-LED of an input flashes constantly or very
often, you should reduce the corresponding input signal slightly. If the PEAK-LED of an output
flashes constantly, the internal gain should be reduced or else the connected device will be
permanently overdriven.
NETWORK-LEDs
If the N8000 is operated on an audio network, e.g.
CobraNet™, these LEDs show the status of the network.
The ACTIVE-LED flashes or twinkles when audio data is
sent or received via the network. If the LED is off, no
communication via the audio network is taking place. The
MASTER-LED is on when the N8000 serves as clock-master - in case of CobraNet™ it is also
named the conductor. There is always only one master in an audio network, i.e. the MASTERLED will only be illuminated on one N8000 within the network. If the unit currently functioning as

clock master breaks down or is removed from the network, another N8000 will take over this
function automatically.
SYSTEM STATUS-LEDs
These LEDs indicate device or system states. The READY-
LED is on when the device has booted after switch-on and
when it is ready for operation. An illuminated FAULT-LED
indicates an internal error in the N8000 or an error in the
NetMax system. During the configuration of the N8000, it
can be specified which errors should be displayed. If the FAULT display is on, the error should be
identified promptly. This can be done using the detailed diagnostics within the IRIS-Net PC
software. The source of the fault has to be remedied immediately.
POWER-LED
This LED is permanently green when the N8000 is powered
on. If the ON indication is not illuminated, even though the
device is switched on, this device may not be connected to
the power supply system or the primary fuse may be faulty.
USB Interface
A PC can be connected at the front panel via the USB
interface. Thus, it is possible to connect the N8000 with a
PC even it is already installed - i.e. when the Ethernet
interface at the rear panel is perhaps no longer accessible.
Via the USB interface the network parameters of the N8000
can be edited and files containing the entire N8000
configuration can be transferred. You can find the necessary USB driver in the subdirectory
\Driver\USB in the IRIS-Net setup directory. Please see chapter Interface description for more
information on technical details concerning the USB interface and the other interfaces of the
N8000 which are described in the following section.

There are all connections for analog and digital audio signals, control interfaces and the power
supply at the rear panel of the N8000.
AUDIO SLOTs
The AUDIO SLOTs 1 - 4 are module slot s for the inst allation of
NetMax audio modules. There are both analog and digital
input and output modules available. Also, a module for
microphone input sensitivity is optionally available. Each slot
can accept any module so you can equip those inputs and
outputs which you need for your specific application. The
N8000 detects the type of the module automa tically and of fers
the corresponding configuration possibilities.
ATTENTION:
The N8000 has to be switched off if you want to change or install a module. You will find
detailed instructions in the data sheet of the corresponding module.
Network Module Slot
This slot is provided for the installation of a network module,
e.g. CM-1 CobraNet™ module. There are all 64 audio
channels - 32 inputs and 32 outputs - internally available at
this slot. The CM-1 allows up to 32 digital audio input signals
and 32 digital audio output signals to be transmitted via a
CobraNet™ network simultaneously. Thus, several N8000
NetMax system controllers can be connected to create a large, distributed audio system. The

N8000 automatically detects an installed network module. The module can be configured in the
PC software IRIS-Net.
ATTENTION:
The N8000 has to be switched off if you want to change or install a module. You will find
detailed instructions in the data sheet of the corresponding module.
ETHERNET Interface
A computer and/or other N8000 devices can be connected
via the Ethernet interface for 100Base-TX / 10Base-T
Ethernet networks. Normally this connection is established
via a standard (straight throug) Ethernet cable and an
Ethernet hub or a switch. If the N8000 is to be connected
directly with a computer or another N8000, a crossed Ethernet cable (crossover cable) must be
used.
RS-232 Interfaces
The N8000 can be connected to external devices, such as
multimedia system (AMX™, Crestron™) or facility
management systems via the two RS-232 interfaces. All
N8000 functions and parameters can be controlled and
monitored via RS-232. Communication is done using an
ASCII parser which is easy to implement. Thus, a NetMax
system can be easily combined with media and touch panel
control systems. A PC can also be connected to the RS-232
port to access N8000 parameters using a terminal program
like Hyperterminal. A special instruction set is available in order to establish a connection to a
PROMATRIX/PROANNOUNCE system. The two RS-232 ports can be configured according to
their corresponding application via the IRIS-Net PC software.
REMOTE CAN BUS
Electro-Voice remote amplifiers and other devices with CAN
interfaces can be connected to the N8000 via the CAN
interface. Up to 100 remote amplifiers can be connected
with a single N8000. All connected components are linked to
the NetMax monitoring and control platform.
The STATUS-LED is provided to monitor the communication
on the CAN bus. If the CAN interface is not in use, the LED
is deactivated. In normal mode the LED flashes every 2

seconds. The duration of the flashing within these 2 seconds depends on the bus load. The
higher the bus load is the longer the duration of the flashing within these two seconds will be.
CONTROL PORT
The CONTROL PORT contains four freely programmable
control inputs, three freely programmable control outputs,
one ready/fault output as well as reference connections for
ground, +5 V and +10 V.
The control inputs IN1 - IN4 are DC inputs, which internally
are connected to ground via pull-down resistors. From
external sources voltages between 0 V and +10 V are
possible. Either switch-mode functions or variable functions
can be programmed for the control input via the IRIS-Net PC
software. Examples of use are: power on/standby switching, preset switching or parameter
control.
The control outputs OUT2 - OUT4 are relay contacts, which are open circuits in off-state (off).
When the output is in on-state (on) the outputs are connected to ground. The outputs are able to
signal internal states and they can directly operate LEDs, indicator lights or relays. The +5 V
reference voltage is able to energize the externally connected elements with up to 200 mA.
Operating states (critical temperature, overstepping or falling below of defined limit values, faults,
etc.) can be relayed to central operation stations or other systems (fire alarm systems, life safety
systems) even without use of a PC via the control outputs. You will find detailed information
regarding configuration of the control ports in the IRIS-Net documentation.
Mains Connector and Power Switch
Please use the enclosed power cable in order to connect
NetMax N8000 to the mains power supply. The N8000 is
compatible with a supply voltage between 100 V AC and
240 V AC. Therefore, a supply voltage switch is not
necessary. Internally, there is a mains fuse which is normally
only blown in case of a fault. The fuse should only be
replaced with an equivalent fuse with identical values for
current, voltage and actuating characteristics by an
authorized service center .
The N8000 can be switched on and off with the power switch on the rear of the device. The ON-
LED on the front panel is immediately illuminated afte r switch-on. The N8000 boots and initializes
all parameters with those values that had been previously active. The initialization takes some
seconds. As soon as N8000 is ready for operation, the READY-LED is also illuminated.
