8×32 Tail Master

Model #: VIM-1832

VIM-1832

The VIM-1832 is normally used in connection with the VIS-1832 or VIS-4832 to achieve a 32×8 fiber-optic transport system. This system is normally the “tail” end for Stage to FOH or drive snake applications.

This device contains 32 analog line level AND 32 AES digital outputs (sends), and 8 analog line level OR 8 AES digital inputs (returns). The VIM-1832 is supplied with a pair of transmit/receive LC fiber connectors (other connector types possible). It also contains a single LC fiber “thru” connector (transmit only) allowing all data coming into the device to be output on fiber and transported to another location. The VIM-1832 contains the system clock. This clock can be switched to operate at 48k or 96k. The VIM-1832 has an external word clock input on a BNC connector, a word clock output on a BNC connector, and super clock output on a BNC connector. The VIM-1832 can “slave” to an external word clock. There are “sync” status LED’s on the front and rear 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 DMX4i (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-1832 or VIS-4832. This data is then output from the “control” EtherCon® connector on the these devices and input into a DMXo or MD-3 where the TTL data is translated back into the original format. AC power is via a standard IEC connector. The unit can operate at any voltage 50-60Hz, 90-250v AC.
