Section 3.0 Operation
3.1 Introduction
Information in this section consists of functional and operational procedures for the PA250 Series High
Power Voice Amplifier.
3.2 General Information
The PA250 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.

3.3.1 POWER Switch
The PA250 Series is switched on by setting the POWER switch to the ‘up’ position (ON).
If the installation uses a remote control (AA21/AA22 or PM01), the ‘power on’ selection will be made at
the remote control.
For a PM01 type remote control, the POWER switch on the PA250 should be set to ‘OFF/REMOTE’. If
the installation uses an AA21/AA22 type remote control, the POWER switch should be set to ‘ON’.
