Talkback & Commentary - CM-CU1
Talkback & Commentary
Commentator Unit 1 Commentator & Line Input
CM-CU1
The CM-CU1 oers the
same high quality, robust
specication as the
CM-CU21, with a feature
set tailored to single
commentator applications.
It provides a fully featured commentator
position and a line-level input. The unit has
an individual commentator output, with
an additional output providing a mix of
commentator and line input audio. A limit
indicator on the main panel shows when
the adjustable limiter on the main output
is active, and a bright 21 segment LED PPM
meter, which can be disabled, shows the
main output level.
The line input can be configured to remain
present at the mix output even if the
commentator is off air, making it useful
for routing crowd effects or pre-recorded
material to the programme feed. Its
presence in the commentator’s headphones
is also configurable to suit the application.
Four talkback output channels, with a built
in limiter, are available to the commentator
and they can be linked to provide
simultaneous operation. Activation of one
or more talkback channels removes the
commentator audio from the main output
until all talkback channels are deactivated.
A wide input gain range and switchable
phantom power allows support of a variety
of microphone types including low output
ribbon mics, headsets and high output
phantom powered microphones. There
are 5 transformer balanced return audio
inputs which, along with the commentator
input, are routed to the headphone monitor
controls. With these headphone controls,

any monitor input can be adjusted and
sent to either the left, right or both ears.
A GPIO port gives an open-collector
driven output indication of any active On-
Air or talkback channel and four remote
inputs provide an external call/alert to
each of the talkback controls.
The unit has a built in line-up tone
generator for easy channel identification
and cabling checks. When enabled the
test-tone is routed to the required output
simply by pressing the corresponding
on air or talkback button. An automatic
tone mode repeatedly sends different
quantities of tone bursts to each output
