CI-ODC-4
The Tech Works CI-ODC-4 Operator Desk Console is part of the Collaborative Intercom
product group. The Console includes a professional cardioid, condenser,
gooseneck microphone, and a speaker. Buttons and indicators provide control to
allow the operator to just listen to the CI-Buss communication or to talk, and
collaborate hands free. A headset jack on the side of the console allows connection
of a local operator headset such as the CS-540 wireless unit.
