Setting up a Bidirectional Talk Back Circuit
The following is a setup example for a specifi c Talk Back circuit with a Boom Op using the 788T with
CL-9.
1. Connect the Boom microphone to Input 1.
2. Set the Output 1 source in the Setup Menu option OUTPUT 1: SOURCE to Input 1. This will
allow the Boom Op to hear his Boom Mic.
3. Connect the 788T Output 1 to the Boom-Op’s headphone amplifi er.
4. Enter the Setup Menu option COMMS: ROUTING. In COM1 Routing select l (Left Headphone
monitor) and 1 (Output 1). This will send the selected communications send source to the
Boom Op’s headphones via Output 1 and to the Sound Mixer’s Left Headphone monitor via
any of the CL-9 Headphone connections when COM1 is active.
5. Connect the Boom-Op’s headset mic signal into the line-level RTN1 Input on the CL-9.
6. Set the RTN1 level. Slide and hold the COM1/RTN1 switch in the right (RTN1) position then
turn the CL-9 Headphone Level Control. This adjusts the return level (Boom Op’s Headset
Mic) sent to the CL-9’s headphone connections.
7. Set the COM1 send level. Slide and hold the COM1/RTN1 switch in the left (COM1) position
then turn the CL-9 Headphone Level Control. This adjusts the Com send level sent to the
COM1 routing destinations. In this scenario this would adjust the Com send signal sent to

headphones).
