Introduction
Fig 1-1: CM-CU1 Commentator Unit
The CM-CU1 Commentator Unit is a high quality, portable broadcast mixer and 4-wire
talkback unit. Its sturdy construction and flexibility of features make it suitable for use in a
wide variety of environments.
It provides a fully featured commentator position with both limited, transformer balanced,
and non-limited, electronically balanced outputs. A limit indicator on the main panel
shows when the adjustable limiter on the mix 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.
They have adjustable gain and can be linked to provide simultaneous operation.
A wide input gain range and switchable phantom power provides support for a variety of
microphone types, from high output phantom units to low output ribbon 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
input can be level adjusted, and sent to either the left, right or both ears.
