Meeting Room, Board Room, Or Church Mixer Using Remote Control; Troubleshooting Tips; No Sound; Distorted Sound - Ashly MX-406 Operating Manual

7.2 Meeting Room, Board Room, or Church Mixer Using Remote Control:

In this illustration, the MX-406 is interfaced with an Ashly VCM-88 eight channel remote level controller,
allowing the mixer to be operated from a distance by a non-technical person. Remote control of the VCM-88 is
achieved through the use of Ashly's RD-8 desk-top remote controller, RW-8 wall-plate version, or PC control using
Protea System Software. The RD-8 and RW-8 use a single mic cable for control data, while PC control uses RS-232
serial communications. Remote control can be located up to 1,300 feet from the main audio equipment rack.

8. TROUBLESHOOTING TIPS

8.1 No Sound

Check the AC power. Is the power switch on? Check the level meters. If they are operating, the problem is
between the mixer and the later components in the system. If there is no meter activity, check to see that you really
have an input signal and that it is on the desired channel.

8.2 Distorted Sound

Something is being overdriven in the signal path. If the clip indicators are active, reduce the channel gain
and/or press in the pad switch on the rear panel. There are many gain adjustments in the mixer itself and probably
several others in other system components which makes it possible to overdrive an input section and then incorrectly
try to reduce the gain of the output section. The best way to approach setting gains is to establish the operating level
of input stages first by setting their gain as high as possible but leaving about 20dB of headroom for loud peaks, then
move on to set the master gain to produce a good meter reading. Proceed to set the gain of equalizers, limiters,
crossovers, and amplifiers following the mixer in the same manner, always working toward the later stages of the
system.
