The following screen shot shows the AES Output Routing screen. The highlighter is in the lower-left

corner.

COM Setup

The 664 features an unbalanced stereo COM Send (TA3) and an unbalanced stereo COM RTN (TA3)

for communications purposes. These special input and output channels can be used to privately com-

municate with a boom operator or other member of the production crew.

During operation, it is possible to interrupt the Com signal and speak to the boom operator via the

slate mic by Holding down the Select Encoder and sliding the Slate/Tone Switch to the left. The green

Slate LED will illuminate to indicate that the slate mic is routed to the Com Send. During this time, the

slate mic signal is sent only to the Com Send Output and right Headphone output, but not to record

tracks or any other outputs. To cancel slate communication and resume the Com Program, slide the

Slate/Tone Switch to the left again. The green Slate LED will turn off.

The gain of the Com Send and Com Return can be adjusted from the Setup Menu options

COMMS/RETURNS > Com Send Gain and COMMS/RETURNS > Com Return Gain, respectively.

COM Send Program

By default, the program sent to the COM Send output is the Left and Right Stereo Bus. To change the

program of the COM Send:

1. Enter the Setup Menu and select COMMS/RETURNS.

2. Select the Com Send Program Option.

3. Turn the Headphone Encoder to select the desired source, and push the Headphone Encoder

to toggle the assignment of the source to the Left or Right side of the COM Send.

4. Optionally, slide the RTN switch to toggle mono or stereo of the COM Send.
