Studio Technologies MODEL-77B
Control Console


The Model 77B is a full-featured control console for use with Studio Technologies Model-76B/77B and Model-76DB/77B systems. Up to four Model 77Bs can be connected to a central controller.

The Model 77B Control Console is designed to be a command center and reside at an operator's location, it allows fingertip selection of all monitoring functions. Numerous LED indicators provide complete status information. Up to six unique input choices are available. Each of the choices can be configured from the system's two surround (5.1) and three stereo (2-channel) inputs. The configuration mode also allows stereo inputs A and B to be used as either stereo or dual monaural sources. This can be especially useful in broadcast applications where a 2-channel AES3id source may carry two independent monaural signals.

A large, easy-to-use rotary digital encoder provides control of the surround monitor output level in precise 0.5-dB steps. A 4-digit numeric display indicates the monitor output or dialnorm level in real time. The monitor output level can be adjusted via the rotary level control, the reference level function, or by way of the dialnorm information included in Dolby E metadata (refer to "Dialnorm Support").
