The Clear-Com PK-7 power supply is housed in a rugged metal chassis and can power up to 30 SMQ-1 or DMQ-2 headsets. It supplies 24 volts DC at .4 amp to the system. The fully regulated, current-limited unit also provides proper termination for the intercom system. The PK-7 features both short-circuit and reverse polarity protection.

Three separate 3-pin XLR connectors are provided for intercom audio and power output to the headset stations. Use Y-type line splitters on these connectors to attach additional headsets to the system.

Simply plug the PK-7 into a standard AC power outlet, attach the headset stations to it using a standard mic cable, and begin talking. Users adjust the volume levels of their headsets to their personal preferences.

The PK-7 power supply is UL and CSA listed.
