Measuring voltage for a

Biamp Precedence CMA 60 amplifier

Several Biamp amplifiers have three screw terminals labeled “remote level”. The control voltage may be indicated (by a “C” in the following picture) on the

panel over the corresponding screw terminal, and the ground terminal is indicated with a .

Even if the voltage is indicated,

use a voltmeter (set to VDC) to measure the voltage as shown in the picture below. Write down the measured voltage for your reference when you set the DIP switches.

Measuring voltage for a Biamp Precedence CMA 60

For three-terminal amps, always connect the MLA- VC10 to the control voltage terminal and ground terminal of the amp’s control port. Leave the other terminal (+10V in this example) open (not connected).

The MLA-VC10 provides a control voltage (supply voltage) of between 0VDC and 10VDC. The MLA-VC10 can control amplifiers that use a higher control voltage. However, if the MLA-VC10 is used with devices that use a control port voltage above 10VDC, the maximum volume will not be reached.

Setting the Configuration DIP Switches

Set the Configuration DIP switches to the setting corresponding to the control voltage required by the amplifier or mixer.

See “Determining the Control Voltage” in this chapter. The table on the following two pages lists all the voltage levels that can be selected. Be sure to set each

switch all the way up or all the way			ON		CONFIGURATION

between the two positions.
