Fig. 30: FirNet™ – Front

Control features Front

1 SPEAKER Key

• Selects a speaker-specific filter set from the FIRNET speaker series database

2 SCENE Key

• Loads scenes setups from the FIRNET database and stores them to the

database

3 LEVEL Key

• Adjusts input and output levels in the range of -40 dB to 12 dB

• Increment = 0.1 dB in the range of 12 dB to -12 dB

• Increment = 0.5 dB below -12 dB

4 DELAY/PHASE Key

• Adjusts delay time up to 500 ms for the FIRNET controller’s inputs

• Adjusts delay time up to 25 ms for the FIRNET controller’s outputs

• Inverts the phase position of the audio signal routed to the FIRNET

controller’s inputs and outputs

5 ADMIN Key

• Locks keys to prevent unauthorized or unintentional handling

• Selects the audio signal input and associated options

• Adjusts peak analog input and output levels to match FIRNET to upstream or

downstream audio devices

• Edits the IP address, controller name, and display contrast

• Serves to select the delay unit of measure (ms, m, ft, samples) and enter the

surrounding temperature to calculate the speed of sound

6 AES IN LED Display

• Lights up blue when the FIRNET controller’s digital AES/EBU IN signal input

is selected

• Extinguished when the FIRNET’s analog signal inputs are selected

EXT SYNC LED Display

• This LED lights up blue when an external AES/EBU signal is enabled for the

FIRNET’s synchronization option and the device receives an incoming signal.

• Extinguished when the controller’s internal synchronization is selected

8 INPUT LED Displays (10 LEDs, green/yellow/red)

• Green segment: Audio input level in the range of -48 to -12 dB at full scale

• Yellow segment: Audio input level in the range of -12 to 0 dB at full scale

• Red segment: Audio input level is overdriving the AD converter

Note: An overdriven AD converter generates -distortion that the FIRNET’s

limiter cannot suppress. If the red LED lights up, set the FIRNET’s input gain

to a higher value (see the section Setting Peak AD Level in the -Adjusting Pa-

rameters chapter) or reduce the source audio device’s -output level! Be sure to

heed the gain level recommendations for -connected amps, particularly when

operating an FP10000Q power amp.

9 LCD

• 2 x 24 characters

• Shows in normal operating mode the controller name, the selected filter, and

the existence of a network link

• Shows options and editable parameters when you access a menu

10 OUTPUT LED Displays (10 LEDs, green/yellow/red)

• Green segment: Audio input level in the range of -48 to -12 dB below the

limiter value

• Yellow segment: Audio input level in the range of -12 to 0 dB at below the

limiter value

• Red segment: Limiter is attenuating the audio input level. The given output is

muted (LED lights up continuously)

11 Back Key

• Returns to the next higher menu level

• Exits edit windows without assigning adjusted values

12 Navigation Keys

• Navigates to the next or previous menu option

• Selects and changes parameters in the edit windows

• Top key: Arrow up while scrolling in the menus

• Bottom key: Arrow down while scrolling in the menus

• Right key to the right to adjust (lower numerical values)

• Left key to adjust parameter values (lower numerical values)

• Enter key to confirm the adjusted value

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 filter selected

• No signal routed to the exits

• All FIR initial coefficients set to 0

• No filters set; filter 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
