Rear Panel Connectors
14 100-240 V~ / 50-60 Hz Mains
This three-pole non-heating equipment connector with a ground contact con-
nects the FIRNET controller to the mains power supply. The multi-voltage power
supply unit allows the controller to be connected directly to all mains voltages
ranging between 100 V and 240 V without requiring transformers and the like.
Its maximum power consumption is 40 VA, which corresponds to about 175 mA
maximum current consumption at 230 V mains voltage and about 400 mA at
100 V. Do not connect the device using anything other than a three-pole con-
nector with a ground contact. The mains outlet must also be equipped with a
ground contact. Never use damaged cords, plugs, or sockets.
15 GPIO
This 25-pin sub-D port provides four each floating inputs and outputs for future
firmware versions’ use, for example, to remote-control power amps or switch
controlled devices. Current firmware does not support this feature.
16 Ethernet PC Control Ports
Ethernet ports relay remote control and monitoring data between a PC and
FIRNET controllers via computer networking hardware. The Ethernet X and
Ethernet II connectors are RJ-45 ports (Input X = for cross input,
II = parallel input).
Cabling:
If you do not wish to use further network hardware such as hubs and switches,
connect the PC’s network port to the first FIRNET’s Ethernet X port using CAT5
network cable. Then also use a CAT5 network cable to connect the first FIRNET’s
Ethernet II port to the second controller’s Ethernet X port, and so forth.
Use a CAT5 network cable to connect the FIRNET controller to hubs or switches,
patching the FIRNET controller’s Ethernet II port to the hub or switch’s network
port. To daisy-chain further FIRNET controllers, connect the first FIRNET’s
Ethernet X port to the second controller’s Ethernet II port, and so forth.
Tip: We recommend that you connect all FIRNET controllers to switches. If you
do not, and one controller fails in setups comprising several -connected FIRNET
controllers, the entire networked chain will drop out.

17 AES/EBU IN Digital Audio Input
Connect signal sources with digital outputs to these three-pin female XLR
sockets. Pin assignments are pin 1 = ground, pin 2 = signal, and pin 3 = signal.
The FIRNET controller accepts sampling rates of 48 kHz and 96 kHz, which
may be selected via a menu option.
Input-Output Signal Routing:
The analog INPUT A – that is, the left channel of the digital AES/EBU signal
- delivers the signal to OUTPUT A and OUTPUT B. OUTPUT C and OUTPUT
D receive their signal from analog INPUT B, that is, the right channel of the
digital AES/EBU signal. You can reroute signals in the LIPAN software’s Admin
window.
18 AES/EBU OUT Digital Audio Output
The signal patched into the AES/EBU input can be routed through in digital
format to other devices via this three-pin male XLR port. Pin assignments are
pin 1 = ground, pins 2 and 3 = signal. The FIRNET amplifi es the incoming digital
audio signal to preserve signal quality. If a FIRNET controller drops out, the
signal is routed directly from the digital AES/EBU IN to the digital AES/EBU
OUT via a parallel circuit.
To select the digital input, go to the Admin menu (press ADMIN once), choose
the menu option Input Options (press 1x
S ), and then press ENTER to confi rm:
Menu option - ADMIN/Input Options/ Input Source
Synchronization Ports for Analog Audio Signals:
If you wish to address several FIRNET controllers via their analog inputs, you
can use digital AES/EBU IN inputs and AES/EBU OUT outputs to synchronize
these controllers to ensure the audio signal remains coherent.
To do this, connect the first FIRNET controller’s digital AES/EBU OUT to
the second FIRNET’s digital AES/EBU IN. Then connect the second FIRNET
controller’s digital AES/EBU OUT to the third FIRNET’s digital AES/EBU IN,
and so forth.
