Universal Beltpack – BP-6000 Introduction 13
System Configuration and Power
System Configuration
The BP-6000 is capable of operating in two different modes:
Audiocom Mode – Balanced, shared power and audio
Clear-Com Mode – Unbalanced, separate power and audio
Balanced and Unbalanced refer to the type of audio signal being used on the beltpack.
Unbalanced Audio – Uses ground reference signalling.
Balanced Audio – Uses differential mode signalling.
Power
The BP-6000 use an external power supply unit, such as a PS-20, PS-2001L, PS-4001, etc to power the
beltpacks. Power is passed through the beltpacks via the Intercom Channel Connector (See Figure 1 on
page 8). Depending upon cable length, up to 35 beltpacks (if powered on two channels) can be daisy-
chained together operating off the same power supply.
Channel Power
The external power supply provides power to the beltpacks in the system via the channel connector on the
power supply and the beltpack. Two power supplies can be used to run a large system or a system that has
a long cable run between sets/banks of beltpacks. Using multiple power supplies can evenly distribute
power throughout system. In a two power supply system, the local power setting on the beltpack is
commonly used.
