Product: StudioComm 76B/77B 5.1 Surround Monitoring System
Optimized for Broadcast
The StudioComm 76B/77B Surround Monitoring System with digital inputs and analog outputs enables simple and effective monitoring of 5.1 surround and stereo audio material. Comprised of a Model 76B Central Controller and a Model 77B Control Console, this system is especially well suited for broadcast master control and post-production applications with analog-input loudspeakers.
Model 76B Central Controller
The Model 76B Central Controller is rack mountable and offers two surround (5.1) and three stereo (2-channel) digital inputs that are compatible with AES3id sources. Sample rates of up to 192 kHz and bit depth of up to 24 are directly supported. Exceptional dynamic range and extremely low distortion ensure that the audio quality of each source is maintained.
The Model 76B Central Controller has eight analog balanced line-level outputs organized as:
Model 77B and Model 71 Control Consoles
The Model 77B Control Console is the "command center." Designed to 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 confi gured from the system’s two surround (5.1) and three stereo (2-channel) inputs. The confi guration 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" below).
The Model 71 Control Console works with the Model 77B to provide additional user locations with the most frequently desired functions: level adjustment, reference level, and dim.
One Model 76B Central Controller can support a combination of up to four Model 77B or Model 71 Control Consoles.
The dialog normalization "dialnorm" value is an integral part of many broadcast distribution systems and represents the average dialog level of an associated audio program, ending up as part of consumer audio playback systems. The dialnorm level value is a component of the Dolby E metadata, and when de-embedded, can be "read" by the Model 76B Central Controller and displayed on the 77B Control Console. By automatically adjusting the surround monitor output level in response to the dialnorm value, a professional broadcast or post-production environment can more accurately simulate the end user's experience.
