13 Reset Button
The FIRNET controller reboots after 10 seconds, and then loads the most
recent settings. Unsaved settings are not retained.
14 Soft Reset and Hard Reset key combinations
The FIRNET offers two more reset functions:
Soft Reset: (Admin+Back+Enter for 3 seconds)
Loading the default preset "Szene O"
Functions:
• No speaker/ no fi lter selected
• No signal routed to the exits
• All FIR initial coeffi cients set to 0
• No fi lters set; fi lter must be reloaded!
• X-Over set to bypass
• Input/ output gain set to 0
• Delay parameter set to 0
• IIR EQs all input gains set to 0,
• IIR EQs output set to bypass (LIPAN Off) and gain to 0
• All limiters set to + 10dB threshold
• Admin parameters remain unchanged
• Outputs 1-4 muted
Hard Reset: Factory default
(Speaker+Admin+Back for 3 seconds)

Rear Panel Connectors
14 100-240 V~ / 50-60 Hz Mains
This three-pole non-heating equipment connector with a ground contact
connects 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 connector 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 fl oating inputs and outputs
for future fi rmware versions’ use, for example, to remote-control power
amps or switch controlled devices. Current fi rmware 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 fi rst FIRNET’s Ethernet
X port using CAT5 network cable. Then also use a CAT5 network cable
to connect the fi rst 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 fi rst 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.
