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.
