FirNet Display
The LCD shows information on presets and parameters. The default
readout appears after the device is powered up, and then the display
indicates current speaker selection settings and the LAN status.
Once you begin navigating adjustable parameters, it shows values
pertaining to these parameters.
FirNet Menu Keys
Menu keys (Speaker, Level, Scene, Delay/Phase und Admin) serve to
access the various parameter sections. You can adjust the indicated para-
meters and save these settings using the edit select keys (cursors and
back key) for the selected input and output. Pressing the back key always
takes you to the next higher menu level.
Note: The device retains stored values even if a power failure occurs or it
is unplugged from the mains supply.
FirNet Channel Mute
• Using Channel Mute Shortcuts to Mute Outputs A/B/C/D
You can use combinations of the Admin menu key and the four other
menu keys (Speaker, Scene, Level, Delay/Phase) to mute the FIRNET’s
output channels in A/B/C/D sequence. For example, if you wish to mute
output A, press Admin + Speaker; to mute output D, press Admin +
Delay/Phase. Press the same combination again to reactivate the output.
Note: Each of the output channels’ red signal LEDs show the given
output’s mute status (constant red = MUTE).
Control features Front
1 SPEAKER Key
• Selects a speaker-specifi c fi lter 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
7 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 Parameters 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
fi lter, 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)
