{"product_id":"pma-4000","title":"PS Engineering PMA4000 Audio Panel","description":"\u003cp\u003ePS Engineering PMA4000 is a compact audio selector panel with a four-place IntelliVox voice-activated intercom, approved under FAA TSO-C50c. It switches two COM transceivers and two NAV receivers and has four unswitched inputs for further receivers or warning audio. The unit is 61 mm wide and 34 mm high and needs 165 mm behind the panel.\u003c\/p\u003e\u003cp\u003eA toggle switch selects COM 1 or COM 2 for pilot and copilot. When power is lost or the selector is set to Off, fail-safe mode connects the pilot headset and microphone to COM 1. The intercom has Pilot Isolate and All modes and a mono music input with Soft Mute.\u003c\/p\u003e\u003cp\u003eThe installation kit in the manual uses a square faceplate; adapter plate 575-004-0001 mounts the unit in a 2¼ in (57 mm) instrument hole. The unit runs on 11–33 V DC; a 28 V aircraft needs a 15 Ω, 15 W dropping resistor in the power input. The manual lists no EASA ETSO, so a certified aircraft needs an approved modification and a Certificate of Release to Service after installation. Fit depends on the aircraft type and the audio panel or intercom being replaced.\u003c\/p\u003e","brand":"PS Engineering","offers":[{"title":"Default Title","offer_id":58182368985419,"sku":"11942_Square","price":29687.7,"currency_code":"CZK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1055\/1063\/3803\/files\/11942_Square.jpg?v=1790587625","url":"https:\/\/shop.airteam.eu\/products\/pma-4000","provider":"AIR TEAM","version":"1.0","type":"link"}
