Plena Voice Alarm System
6.3.2

Vox

If the Vox switch is in the OFF position, the input is activated when the voltage of the signal of
the source is above the specified threshold. If the Vox switch is in the ON position, the input is
activated when the VOX Switch trigger input is closed (see also section 5.1.9 ).
6.3.3

Speech filter

If the Speech filter switch is in the OFF position, a speech filter is activated for the mic/line
input with VOX functionality. The speech filter improves the speech intelligibility by cutting off
the lower frequencies.
6.3.4

Phantom power

If the Phantom power switch is in the ON position, a phantom power supply is activated. This
switch only has to be put in the ON position if the source is a microphone that must receive
phantom power. If the source is not a microphone or if the microphone does not accept
phantom power, leave the switch in the OFF position.
