MLA-VC10 Functional Block Diagram
2-16
The amplifier accepts a higher control voltage than the
MLA-VC10 provides, so the amplifier will not reach its
highest volume level. Try another amplifier with a lower
control voltage requirement.
If audio output does not reach the amplifier’s maximum
volume
If you use an MLA-VC10 with an amplifier/mixer that has a
control voltage requirement above 10VDC, the maximum
volume may not be reached.
If volume changes lead to erratic variation in output
volumes
Verify that each DIP switch is set either all the way up or all
the way down, not partway between up and down
positions.

CONFIGURATION
Leaving a DIP switch in the middle can cause
unpredictable changes in volume: the switch
intermittently varies between on and off settings, yielding
control voltages from two different ranges: one range
that’s appropriate for your equipment, and one that isn’t.
If the audio output can still be heard when the MLA-VC10
has a volume setting of 0VDC
Check the gain and level settings on the amplifier or mixer.
Adjust the gain so that you don’t hear any audio output
when the MLA-VC10 is set for 0VDC output (minimum
volume).
