Selects whether microphone 1, connected to the rear
DIN-socket, will have priority over microphones 2 and 3
and the background music. This will mute these
microphones and the music and will also override zone
switching and zone attenuation.
Closing contacts 4 and 5 will activate priority.
Selects whether microphone 1, connected to the front
6.3 mm phone jack socket, will be VOX activated. As
VOX activated microphone, microphone 1 will attenuate
the background music or microphones 2 and 3 to a
preset ducking level as long as you speak into the
microphone.
Selects whether a chime signal will precede a priority call,
started by microphone 1, upon closure of contacts 4 and
5 of the rear DIN-socket. Additionally, the chime level
control allows for setting the volume of the chime.
Selects a flat frequency response for microphone 1 or
activates a speech filter, that improves intelligibility by
attenuating the low frequencies.
Switches the phantom power supply for microphone 1
(DIN-connection only). Phantom power should be
switched on for condenser or electret microphones (e.g.
LBB 1950) and switched off for dynamic microphones.
Switches the phantom power supply for microphone 2.
Switches the phantom power supply for microphone 3.
