32×8 Digital Head

Model #: VIS-4832

VIS-4832

The VIS-4832 is normally used in connection with the VIM-1832 or VIM-MY32 YGDAI cards to achieve a 32×8 fiber-optic transport system. The VIS-4832 / VIM-1832 or VIM-MY32 system is normally used as a transport for STAGE to FOH with or without splits, using other manufacturers digital mic-pre’s input to the VIS-4832. This VIS-4832 / VIM-1832 system can also be used as a 32 channel drive snake.

This device contains 32 AES digital inputs and 8 analog OR 8 digital outputs (returns). There are word clock & super clock outputs presented on BNC connectors. The VIS-4832 is supplied with a pair of transmit/ receive LC fiber connectors (other connector types possible). 2 fiber optic splits are available as an option. These splits (transmit only) are presented on single LC connectors. The VIS-4832 will operate at 48k or 96k There are “sync” status LED’s on the front and rear panels of the unit. These LED’s will be solid green when in sync, flashing red and green while looking for sync, and solid red when no sync is present.

The “control” connection is a TTL data port which appears on an EtherCon® connector. It allows LightViper accessory devices such as the DMX4o (DMX lighting control) or MD3 (RS422/232/MIDI) to be connected to the unit. The EtherCon® output of the DMX4i or RJ45 on the MD-3 is input to the VIM-1832 via the “control” EtherCon® connector, combined with the audio input data, and transported via fiber to the VIS-4832. This data is then output from the “control” EtherCon® connector on the VIS-4832 and input into a DMXo or MD-3, where the TTL data is translated back into the original format. The VIS-4832 is convection cooled. AC power is via standard IEC connector. The unit can operate at any voltage 50-60Hz, 90-250v AC.
