The Stage Box - VIS-1832
Input - Each of the 32 inputs on the Stage Box is a Neutrik, XLR/TRS
1
combo connector. Each input has 3 switch-selectable gain settings: 0
dB, 26 dB, and 46 dB. All inputs accept balanced or unbalanced signals,
eliminating the need for adapters and DI boxes. The Clip LED will flash at
3 dB below peak clipping. (+16 dBu). The XLR inputs of the VIS-1832
have an input impedance of 1.8KΩ while the TRS has an input
impedance of 1.8KΩ.
Return - Each of the 8 returns are made via Neutrik, XLR, male
2
connectors. Returns are all line-level.

Phantom Power - 48V Phantom Power is switch-selectable in
groups of eight inputs (1-8, 9-16, 17-24, 25-32) When switched on, the
Phantom Power LED for that group will glow green. The 1/4" inputs of
the Neutrik Combo connectors on the VIS-1832 are normalled so that
phantom power is disconnected on a channel by channel basis when a
1/4" jack is inserted. This allows you to use these connectors in a bank
that has phantom power enabled without fear of putting phantom
power on your 1/4" line.
Phantom power on the console should be turned off for Light Viper
connected inputs as this could cause distortion on the channel.
Sync - The Sync LED indicates the status of the fiber optic link between
4
the Stage Box and the Mixer Box. It has three states:, SOLID RED indicates
there is no optical link present, ALTERNATING GREEN AND RED means the
unit is searching for sync, SOLID GREEN - indicates optical link is present, and
OFF indicates no power.
5
Fiber Connections - Each Stage Box has one to three fiber
connections. The one marked 'Primary' should always be connected to
the Mixer Box (VIM-1832) as it provides clock for the entire system. Any
other connections would be made to additional send boxes. Always be
sure to use appropriate fiber and connectors. The LightViper 1832
system uses multimode fiber. Single mode optics are available for
situations where single mode fiber may already be installed.
Control Circuits Connector - This RJ-45 jack provides (3) bi-
6
directional CMOS or TTL data lines (up to 38.4 KHz from Stage to FOH
and 2MHz from FOH to Stage) plus voltage and GND. THIS IS NOT AN
ETHERNET CONNECTOR —CONNECTING AN ETHERNET DEVICE TO THIS
CONNECTOR COULD DAMAGE THE DEVICE. The Pin-Outs for this
connector are detailed in the Appendix. Most CMOS or TTL
functions/equipment can be adapted to make use of this connector.
Power Connector - Power to the Stage Box is provided with the
7
supplied Neutrik "Powercon" power cable. The internal power supply can
accept 90-260V at either 50 or 60Hz. VIM-1832 and VIM-1032 units use
standard IEC power cables. The supplied power cord will be appropriate to
the country of delivery.
Fuse - The power fuse is a 5x20 mm, 1A Slo-Blo. Only replace the fuse
8
with an exact match. If after replacement the fuse blows again, return the
unit for service.

The gain settings correlate to output levels as follows:
A setting of 0, an input signal of 0dBu will produce an output at the VIM-
1832 of 0dBu.
A setting of 26, an input signal of -26dBu will produce an output at the VIM-
1832 of 0dBu.
A setting of 46, an input signal of -46dBu will produce an output at the VIM-
1832 of 0dBu.
Typical uses for each gain setting:
0 dB - Line level instruments/equipment (eg. Keyboards, CD player, etc)
26 dB - Condenser microphones, "hot" dynamic microphones.
46 dB - Low output condenser microphones, dynamic mics.
