CI-ODC-1
The Tech Works CI-ODC-1 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.
