Upgrade your aircraft’s audio system with the King KMA-28, a feature-rich audio panel designed for seamless communication and superior sound management in the cockpit.  The KMA-28 is the King version of the PS Engineering PMA-8000 (and is a slide-in replacement for the Garmin GMA-340).

Clear Communication for Every Flight
The KMA-28 features a 6-station Intercom with IntelliVox® automatic squelch control, ensuring crystal-clear voice transmission by adapting to different microphone sensitivities. Each microphone input has its own voice-activated squelch circuit, reducing background noise and eliminating the need for manual adjustments. (A one-size-fits all squelch can let in background noise and/or make it difficult to communicate due to cut-off speach.)

Efficient Cockpit Audio Control

• Split-COMM functionality allows the pilot and copilot to utilize separate COMM radios simultaneously, which is ideal for high-traffic airspace or training environments.
• LED-illuminated audio selection buttons provide instant visual confirmation of active channels, reducing workload.
• Marker Beacon Receiver and Indicator ensure you never miss a critical waypoint on an instrument approach.
• Built-in audio amplifier delivers powerful, clear audio to your cabin speaker.

 Enhanced Entertainment & Safety Features

• Dual stereo entertainment inputs let you connect multiple audio sources, while an automatic muting function ensures incoming COMM transmissions always take priority.
• Emergency mode provides direct access to COMM #1 in case of power failure, keeping you connected when it matters most.
• Optional "key click" feedback can be toggled on or off for additional audio response during operation. (Hold the COM 1 and COM 2 buttons for 5 seconds to toggle on/off.)

Seamless Integration with Silver Crown Plus Avionics

Designed to complement the Silver Crown Plus series (such as the KX-155A and KLN-94), the KMA-28 features a backlit bezel for enhanced visibility and a professional, modern aesthetic.

Upgrade to the King KMA-28 and experience uncompromising audio performance, intuitive controls, and reliable communication in every phase of flight.
