Section I General Information Introduction The PM3000 is an FAA-TSO approved, panel mounted, 4- to 6-place highfidelity stereo intercom system (ICS). Please read this manual completely before using the unit to become familiar with all its features.
the option to listen to music during flight. During intercom or aircraft radio reception, this music will automatically mute to allow communications without distraction. When the activity ceases, the Soft Mute™ circuit gradually returns the music to the original listening volume. By depressing the “Mute” control (located on the Squelch knob) once, it is possible to have the music remain at a constant level, regardless of any ICS or radio traffic.
Section II Operation PM3000 (11931(A) & 11933A) Adjusting the Volume (1) The PM3000 volume control knob adjusts the loudness of the intercom and music only. The volume control on the PM3000 does not affect the volume level of the aircraft radio. This allows the aircraft radio and intercom volume to be balanced independently. The volume control affects the music level for the pilot and copilot positions. By turning the control clockwise, the audio level will increase.
Music # 2 passenger volume in CREW mode (11932 and 11934) version is a fixed level, and controlled locally by the headphone volume control or music device. Adjusting the Squelch Control (2) This VOX operated intercom keeps all microphone channels off (silent) while the pilot, copilot or passengers are not speaking. This reduces background noise from the aircraft. Only when someone speaks will their microphone turn on, allowing the audio to pass through the system.
ALL (Middle position): All parties will hear the aircraft radio, intercom, and music. However, during any ICS conversation, the music vol- ume automatically mutes. The music volume increases gradually back to the original level after communications have been completed. CREW (11932, 11934 only) (down position): Pilot and copilot positions will hear aircraft radio and music number one. Passengers will only hear other passenger’s intercom, and music number 2.
Section III Warranty and Service In order for the factory warranty to be valid, the installations in a certified aircraft must be accomplished by an FAA-certified avionics shop and authorized PS Engineering dealer. If the unit is being installed by a non-certified individual in an experimental aircraft, a factory-made harness must be used for the warranty to be valid. PS Engineering, Inc.
