'General Flags'
Designation
Function/meaning
'Pilot Tone'
Enables the pilot tone, which is mandatory for the 'LineDetection' function.
'Line Detection'
Enables communication with the LD extension interface.
'Eject Shortcircuit'
Switches the speaker line off automatically in the event of a short-circuit.
'Class A Loop'
The start and end of a loop speaker cable are connected to a 'Digital audio matrix
(4/4/16)' or Cerberus PACE Compact digital audio matrix board. No loop isolator
is used. Normal operation: the loop is controlled as a string. Signal fault: the
second relay controls the loop as two strings. Short-circuit: the loop is switched
off.
'Backup Control'
If this flag is enabled, this device is part of a backup amplifier concept. The device
will switch to a backup amplifier if a program amplifier is defective.
'Pilot Auto Gain'
Automatically adjusts the levels of the analog outputs to the values set under
'AutoGain Voltage'. Has to be switched off again once leveling is complete, as
otherwise faults with the amplifiers or speaker line may not be detected.
'Alarm Gains'
Changes the levels of the analog outputs in the event of an alarm (available on
the PC2003 and Cerberus PACE Compact digital audio matrix board only).
'Check Mike'
Enables the microphone monitoring.
'Check NetRedundancy'
Enable the monitoring of both physical network ports of the device and raise an
error if the network redundancy check fails.
'En Maintenance'
Used for 'LineDetection' servicing, raises an error immediately after detection
'Pilot Tone'
Designation
Function/meaning
'Line Fault Holdback Time
(t LFH)'
Defined time for fault suppression on the speaker line.
Causes (Interval Time of)
Starts a measurement every n seconds.
LP On
Pilot tone on (duration in [s]).
LP Off
Pilot tone off (duration in [s]).
Auto Gain Voltage
Enable Pilot AutoGain and enter the required pilot tone voltage for all amplifier
channels. The value should match the Pilot RMS Value parameter.
Pilot Gains/Alarm Gains
Switching between Pilot Gains and Alarm Gains (available on the PC2003 and
Cerberus PACE Compact digital audio matrix board only).
Gains
Gain level for the pilot tone at the matrix amplifier output. Set the gain level for all
four analog audio outputs.
