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.

• 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.

operation in the event of an emergency when the VAR Router is not fully operational
for any reason.
