Determining the Control Voltage

The MLA-VC10 drives the ampliﬁer's or mixer's remote control

port. Different models of ampliﬁer or mixer may require a

different voltage to control the audio volume. You need to know

the speciﬁc voltage requirements of your equipment before you

can conﬁgure the MLA-VC10 to control it.

Sometimes the equipment's manual lists the required voltage,

but usually you will have to test the voltage yourself, using a

voltmeter. This section describes how to measure the control

voltage for some widely used ampliﬁers.

Most ampliﬁers come in one of two basic conﬁgurations:

two-terminal (control and ground)

three-terminal (reference, control, and ground)

The MLA-VC10 works with a wide range of ampliﬁers.

The models shown in this section are included as

examples only. The MLA-VC10 is not limited to

working with only the ampliﬁers shown in this manual.

The next two pages show how to measure control voltages

on "typical" amplifers: the Peavey UMA 35T II (page 2-4) and

Biamp Precedence CMA 60 (page 2-5).

Following that, two special case ampliﬁers are described: the

TOA 700 series (page 2-6) and 900 series (page 2-7).
