A StudioComm for Surround system starts with the Model 78 Central Controller. Occupying just one rack space, it allows connection of two 8-channel inputs and an 8-channel monitor output. The Model 79 Control Console is a compact, comfortable command center designed to reside at the operator’s location. With the StudioComm for Surround system any audio console, disk-based recording system, or broadcast facility can have a complete 7.1 multichannel monitor system.
The Model 78 Central Controller is a single rack-space unit that contains analog, digital, and power supply electronics. Two 8-channel analog sources can be connected. In many applications the first input, Surround A, will be connected to a multichannel output on an audio console or digital audio workstation. The second input, Surround B, will be connected to a playback device, such as a multitrack tape recorder or disk storage system. For film or video post applications Surround A would be considered the direct source, while Surround B would be considered the playback source. For flexibility, the inputs are compatible with balanced or unbalanced signals having a nominal level range of –12 dBV to +6 dBu. Fifteen-turn trim potentiometers are used to precisely calibrate the input signals.
