BEFORE YOU BEGIN
The PK-7 power supply supports a system containing up to 8 Clear-Com beltpack
stations. This compact unit supplies 22 to 30 volts DC at 400 milli-amperes,
terminates the system, and incorporates short-circuit protection.
Compact and rugged, the PK-7 is ideal for portable applications especially when they
require speedy set-up and break-down. The mains supply is a universal input model
with a standard IEC inlet and simply plugs into the rear of the PK-7. Enclosed in a
heavy-duty metal box are three separate 3-pin XLR connectors for intercom output to
the headset stations. Red and green LEDs provide status information on the operation
of the unit.
