from the PM-3000
Balanced Output to a
standard XLR-type of
balanced amplifier input.
2. This figure shows wiring
from PM-3000 Balanced
Output to an unbalanced
input. Note: this wiring
style into an unbalanced
input will result in 6dB
less maximum input sig-
nal. The unbalanced
connection shown in 3. is
preferred.
3. Wiring for PM-3000 into

Note 1. In some instances, connecting the cable shield
to both the PM-3000 ground and the amplifier’s input
