Induction Loop Output Override Gain Configuration
Each VAR Router output is equipped with an ‘override gain’ setting. This enables each zone to be
independently adjusted for the level of the audio in the hardware bypass failsafe mode when the VAR Router
is in the Failsafe Override mode.
In order to configure the override gain proceed as follows.
1. Select

.
2. Scroll the output list and select the required induction loop output:
[O/P #1 - OUTPUT 01]
Default value:
output 1
Outputs:
4 outputs for VAR4
12 outputs for VAR12
20 outputs for VAR20
The output name is shown on the right side of the display. The output name above is the
output 1 default name, however this may have been changed according to each site’s
configuration.
Standard output override gain configuration is described in Section “
12.5 Override Gain
Configuration
”.
3. Move to, and select the
Override
menu item.

4. Scroll the override level until the required value is displayed in the right field:
[Gain(dB)=-30]
Default value:
‘

30’
Possible values:
−
63 to 0dB (1dB steps)
•
While in this menu the VAR Router is put into the hardware bypass failsafe override
mode. This is so that if the Fire Microphone PTT is operated it uses the analogue
override path NOT the normal DSP path. Therefore the Fire Microphone can be used
to demonstrate the effect of adjusting the override gain in order to correctly set the level
of the Override Mode gain.
•
It is essential that these levels be correctly set to ensure correct emergency broadcast
operation in the event of an emergency when the VAR Router is not fully operational
for any reason.
