Control Circuits Connector ‐ This RJ‐45 jack provides (3) bi‐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 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 with an exact match. If after
replacement the fuse blows again, return the unit for service.
Clip LED – The Clip LED will flash at 3 dB below peak clipping. (+16 dBu).
Gain Switch – Each input has 3 switch‐selectable gain settings: 0 dB, 12 dB, and 26 dB
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 12, an input signal of ‐12dBu 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.
Typical uses for each gain setting:
0 dB ‐ Line level instruments/equipment (eg. Keyboards, CD
player, etc)
12 dB ‐ Condenser microphones, “hot” dynamic microphones.
26 dB ‐ Low output condenser microphones, dynamic mics.
