Surround Select Unit
Control Room Source Selection for 5.1 Surround and Stereo Signals with 10 Inputs
The unit is fitted with 10 switches for the selection of signal sources and can also be applied as an input selector for a set of VU or Peak Meters. It fits into slot 9 of the 4U high mounting frames.
The electoral surround select unit operates passively. The symmetric audio circuit uses high quality relays and a logic group. The logic causes the mutual release of the circuits and produces a break before make delay, which prevents a summing of the signal sources during the switching process. The unit selects one of 12 signal sources and puts this on the output.
The switches 2TR-1 TO 2TR-4 switch 4 equivalent stereo signal sources that can all be put on 1 D Sub connectors. The inputs for MIX and CUE and AUX1 and AUX2 serve in connection with an INTEGRATOR mixer system in order to monitor the masters. However, electrically they are implemented as stereo-inputs, so any application is possible. The MIX input is a 5.1 source. There are 2 additional 5.1 sources for external surround equipment, 6TR-1 and 6TR-2. The color and inscription of the switch caps can be customized, and a coupling of several units is possible.
The surround select unit uses all available connectors of the slot 9.
