32×8 Analog Head

Model #: VRK-1832 | VIS-1832

VRK-1832 | VIS-1832

The LightViper® VRK-1832 is used in connection with the VIM-1832 or VIM-MY32 YGDAI cards to achieve a 32×8 fiber-optic transport system. The VRK-1832 or VIS-1832 is the “head” end for Stage to FOH or drive snake applications. The VRK version is a 5U rackmount configuration and the VIS is more of a floor box package. 

VIS-1832

This device contains 32 mic/line inputs (sends) and 8 analog line level outputs (returns). There is a 3 position gain switch for each input that sets the gain of the mic-pre. The normal settings for these switches are as follows: 0 = line level, 26 = mic level, 12 = high transient / very “hot” mic level.There are 4 +48v phantom power on/off switches with associated on/off LED indicators. Phantom power is applied in groups of 8 inputs.

The unit is supplied with a pair of transmit/receive LC fiber connectors (other connector types possible). Two optical splits come standard. These splits (transmit only) are presented on a single fiber each. The VIS-1832 will operate at 48k or 96k sampling rate. 

The system features a “control” connection which 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.
