Installation and Setup, cont’d

•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		UP	CONFIGURATION
1	2 3 4 5 6 7 8		1	2 3 4 5 6 7 8
ON					DOWN
	0 to 10.0VDC			0 to 4.98VDC	NOT HALFWAY

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).
