OPERATION

SYSTEM POWER

The BP-2000 belt pack receives power externally, in one of
two ways:
· Via the intercom channel (similar to the BP-1000)
· Via the local-power (pin 2) of the intercom channel
connector
The BP-1000 belt pack receives power externally, via the
intercom channel.
Both the BP-2000 and BP-1000 will pass system power
through to subsequent belt packs that are "daisy chained"
together.
INITIAL BP-2000/BP-1000 SETUP
The channel termination is initially set for balanced operation,
which is compatible with other Audiocom® equipment. If the
unit is going to be connected to Clear-Com equipment, one
switch and several jumpers must be changed as described in
the section on Clear-Com Setup in this manual.
The headset microphone type is initially set for single-ended
dynamic operation. To change the microphone type to
balanced dynamic, refer to Table 2 for the position of J15.
To change the headset microphone to an electret type, refer
to Table 2 in this manual for the position of switch SW1. If the
type requirement of a headset microphone is unknown, the
recommended setting is single-ended dynamic.
