Vicon V1332AF-1 Relay/Audio-Follow Video Switcher, mono, 32 inputs, for use with matrix switching systems.
Switches audio at same time as video
32 balanced inputs
Monaural or stereo
Cascadable
The V1332AF and V2332AF Series Relay/Audio-Follow-Video Switchers are microprocessor-controlled units that allow audio devices associated with video systems to be switched at the same time as the video. All models provide passive relay-based audio switching. In the following specification, the model number V1332AF will be used to refer to all models unless specified otherwise.
This series of relay switchers is compatible with Matrix 44™ and Matrix 66™ switchers and with Nova™ VPS™1300, VPS1344, and VPS328 digital control systems. In a typical application, the audio signal from an intercom microphone associated with a video camera can be switched to a speaker at the guard station at the same time the video is switched to the guard’s monitor.
Two basic models of the relay switcher are available: the V1332AF provides 32 balanced monaural inputs, while model V2332AF provides 32 balanced stereo inputs. Each input/output of the V1332AF has two relay contacts. The V2332AF supports stereophonic audio systems or other systems requiring four contacts to be active at each switch. Input/output proportions are configured by setting internal jumpers and include the following combinations:
V1332AF:
32 inputs, 1 output, mono-balanced;
16 inputs, 2 outputs, mono-balanced;
8 inputs, 4 outputs, mono-balanced;
V2332AF:
32 inputs, 1 output, stereo-balanced;
16 inputs, 2 outputs, stereo-balanced; 8 inputs, 4 outputs, stereo-balanced.
Multiple relay switchers may be cascaded, and the provision of a combiner circuit enables them to be used with switching systems of more than 256 cameras. Relay connections are made via convenient detachable screw terminal blocks.
Both inputs and outputs are balanced to provide maximum hum and noise rejection. Unit specifications have been designed for a high-fidelity range and include: crosstalk: better than -70 dB at 20 kHz; frequency response: flat within 0.3 dB from 10 Hz to 20 kHz; hum and noise: typically better than -60 dBm.
