Measuring voltage for a Peavey UMA 35T II

ampliﬁer

Control Terminals for Peavey ampliﬁers usually consist of two

screw terminals. In the example shown below, they are labeled

"Remote Vol". Use a voltmeter, set to VDC, to measure the

voltage.

Figure 2-3 — Measuring control voltage for a Peavey

UMA 35T II: Meter probes are oriented correctly.

In ﬁgure 2-3, the measured voltage is positive, so the right

terminal is the signal connection and the left terminal is ground

connection. Write down the measured voltage and which

terminal is ground as this will be important when you set the

DIP switches. If the voltage is negative (see ﬁgure 2-4), the

meter's probes are touching the wrong terminals.
