CM-CU1 Front Panel Controls & Connections
The front panel of the Commentator Unit has the commentator input and
headphone output as well as the microphone power and gain controls.
Phantom Power Select Switch
The commentator input supports phantom powered microphones. The
commentator position has a dedicated phantom power switch that enables
the 48V supply.
Microphone Input Gain Controls
The commentator microphone input has an adjustable gain setting. The
total gain range of +20dB to +86dB is split into two, to provide greater
accuracy of adjustment. The mic gain switch sets the base gain value of
20dB or +50dB for the input. The mic gain potentiometer can then
be adjusted to add up to 36dB of additional gain.
Headphone Output
The front panel mounted headphone output is via a ¼” stereo jack socket,
which is locking to prevent the headphone plug from being accidentally
pulled out.
