1.5 Auxiliary Components
The PA700 Series amplifier is designed to operate with specific compatible components to form an
effective sound system.
1.5.1 Control Panel
1.5.1.1 AA21
The AA21 Cabin PA control unit is designed to provide centralized control for an aircraft’s internal and
external PA systems. The unit is panel mounted with an illuminated NVIS Green B compliant faceplate
and a front panel switch to provide selection of the various operational modes. The AA21 provides two
low level audio signal outputs that drive the input on remote mounted power amplifiers. One output is
designed to drive the PA110/220 series amplifiers and the other output is designed to drive the
PA250/700 series amplifiers.
1.5.1.2 AA22
The AA22 PA/Siren control unit is a compact, self contained, Dzus mounted unit for use with the PA250
and PA700 series audio power amplifiers. It has a low level output rated at 500 mVrms. It provides a
centralized control for external audio paging and siren functions.
1.5.1.3 PM01-001
The PM01-001 is a remote control device designed as the operating station for a high power audio
system. The PM01-001 is equipped with two decibel meters which make it ideal for monitoring either one
or two power amplifiers.
1.5.2 Microphone
1.5.2.1 PM03-002
The PM03-002 is a hand-held, dynamic and noise-cancelling microphone with a push-to-talk button. It
comes with a coiled retractable cable and connector for direct connection to the amplifier or remote
control unit such as the PM01-001.
