Jumpers
Jumpers are to be adjusted
prior
to applying
power to the MVXA monitor panel. Jumpers
have an extended tab for ease of placement.
Always put the jumpers on the same numbers.
EX: 1 & 2, 3 & 4, or 4 & 5. No jumpers are used
for the 100 volt input setting.
Terminal Inputs
Each of the unit's eight or sixteen channel inputs is
independent allowing audio and visual monitoring of any
combination of 25V, 70V, 100V, and line level circuits.
Each channel provides level indication and is selectable
to a "0" dB reference through easily accessible jumpers.
The available references are shown in Figure 2.
Since each channel is independent, the MVXA can
monitor multiple signal types. For example: Ch1 could
be a line level, Ch2 the 70V output from an amplifier,
Ch3 a line level from another source, etc.
The default setting for all channels is 70V.
Rear Panel Cover
(not shown)
The protective rear panel cover should be placed on the
unit after wiring to avoid accidental contact with rear
terminals. The cover has knockouts on each end to help
with wire management.
Figure 2
Choose jumper settings to match desired 0 dB reference (25V, 70V, 100V, or line level).
