Operating Manual -MX-508 Stereo Microphone/Line Mixer
6. TYPICAL APPLICATIONS:
6.1 Small Sound Reinforcement System:
In the setup shown here, the MX-508 is used to mix typical sound sources that might be found in a small club, school
theater or similar environment. Six of the input channels are used for microphones for live vocal or instrumental
pickup. The remaining two channels are used for playback from a stereo tape recorder, such as might be used during
intermission, for backup, for special recorded effects, etc. The power amplifier (or any additional equalizers or elec-
tronic crossovers which may be used) is fed from the transformer balanced Output connectors.
6.2 Meeting Room, Board Room, or Church
Mixer Using Remote Control:
In this example, the MX-508's send/
return insert jacks are interfaced with an Ashly
VCX-80 eight channel remote level controller,
allowing a full-featured mixer to be operated
from a distance by a non-technical person.
Once initially set up, the RD-8 desk-top remote
controller (or RW-8 if a wall-plate version is
desired) can be located far away (up to 1/4 mile)
from the main audio equipment rack using a
single balanced XLR cable, allowing for sim-
plified sound system operation. A limited num-
ber of knobs, lights, and buttons saves the VIP
operator from distraction and potential embar-
rassment, while giving them a great deal of
overall system control. While only two zones
are shown, the MX-508 can independantly con-
trol audio to five different zones at once. Each
of these zones could just as easily be controlled
by the VCX-80 by interfacing with the mixer's
outputs.
