General Information
The PA700 Series is built within an aluminum chassis, which provides a rugged case and an excellent
heat sink. Removable side panels protect the power components mounted between the cooling fins from
accidental contact with metallic objects. These panels are easily removed to gain access to the
components. Operating features are the Press-to-Test indicator lamps, the gain control, the microphone
and recorder input connectors, the POWER switch and the power-input / speaker-output connectors.
