PS Engineering Advances Audio System in New PMA450A



This year at AirVenture, PS Engineering  announced an updated PMA450A, featuring a new graphics display and USB port. Based on Organic Light Emitting Display (OLED) technology, the larger, enhanced screen features easy-to-read white text on black. Since the display is bigger, the USB charging port has gotten smaller and more powerful. The new USB-C standard connector is non-directional and non-gendered, which means both ends are the same, and there is no up or down. It’s very easy to connect in the cockpit. The power available also increases from 10 to 15 Watts.

The PMA450A has an optional PS Streamer Bluetooth module—for streaming selectable cockpit audio signals that can include just the radios or everything the pilot hears—to a device such as a compatible video camera capturing the whole flight experience in sight and sound.

The PMA450A also adds an independent Bluetooth music input for distribution. Now there are three independent music sources that can be distributed to anyone in the aircraft.  With these advancements, the pilot, copilot, and passengers all can share or listen independently to their music source of choice.

Another sought after intercom function is the “copilot as passenger” mode, which treats the intercom station at the copilot seat like a passenger for music distribution and radio communication.

When the original PMA450 was introduced in 2014, PS Engineering brought IntelliAudio, true dimensional sound, to the general aviation community. It was also the first and only audio panel with a built-in graphics display and soft-key interface that all but eliminates the need for a pilot guide. The PMA450A takes these features one more step, making it the most advanced and easiest-to use-audio panel available. These enhancements solidify its place on top of the stack.

List price of the PMA450A is $2,595. The optional PS Streamer Bluetooth module is $149.95.
