PRO Intercom Footswitch
OVERVIEW
The Hear Back PRO Intercom Footswitch allows one
microphone to serve a dual role as both a vocal microphone
and as an intercom microphone for discrete communication
with other band members or the sound engineer.
The Intercom Footswitch features a silent mute design;
it mutes the microphone signal going to the sound board
without any pops or clicks. The microphone signal is then
routed to the Hear Back PRO Mixer along with a special
22kHz signal that automatically engages the intercom
feature on the Mixer (firmware v1.3 or higher*). The 22kHz
signal is not only above the human hearing range, it is also
at a very low level – just enough for the Hear Back PRO
Mixer to detect.
The switch is momentary, so as long as you hold your foot on
the switch, the microphone will route to the intercom instead
of the sound board. All outputs are transformer isolated from
the microphone and each other. A special phantom-power
circuit allows the microphone to be powered from the sound
board (if the microphone requires phantom power).
You can also use the footswitch in any application where an
A/B momentary footswitch is needed.
