Studio Technologies StudioComm Model 55 Central Controller - Used

Type: Used
Condition: Excellent

The Model 55 Central Controller and the Model 56 Control Console work together to provide the features and flexibility that help reduce the time and cost of audio product-ion. A complete system consists of a rackmounted central controller, a desktop control console, and one or more talent amplifiers. The Model 56 is connected to the Model 55 with a 5-pin, 5-conductor, MIDI-type cable. The units communicate using system exclusive MIDI messages.

Model 55 Central Controller
The Model 55 is the connection point for all audio inputs and outputs, and provides power for the Model 56 and the talent amplifiers. Front panel LEDs indicate the functional status of the Model 56 and the talent amplifiers, and data flow from the Model 56.

Four Stereo Line Inputs
The analog outputs of workstations, DAT recorders, optical CD recorders, CD players, cassette decks, or virtually any analog source can be connected to the Model 55’s line inputs. The inputs accept balanced or unbalanced signals, and can be individually configured for either –10 dBV or +4 dBu operating levels. Each input can also be configured to accept a stereo or mono signal. 

Control Room Output
The Model 55 provides a balanced stereo line level output for driving a power amplifier associated with control room monitor loudspeakers.

Dub Output
A balanced stereo line output is provided for dub (copy) use. The dub output can be switched between –10 dBV and +4 dBu
operating levels.

Meter Output
The meter output provides a stereo line-level signal that “follows” the source(s) selected for the control room. The signal is not affected by the control room level circuitry, but does reflect the monaural function. The meter output is intended to be connected to VU- or PPM-type meter panels that contain series current-limiting resistors or input buffer amplifiers.

Headphone Output
The headphone (cue) output is designed to feed up to four StudioComm talent amplifier modules. The output is a 3-conductor XLR-type connector that provides power and left and right audio to the talent amplifiers. The Model 70 Interface is available to convert the talent amplifier output to separate left and right balanced line outputs.
