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.

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.

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
