Question about ICOM A200 audio wiring

[ChiefPilot]

Hi All,

I'm getting tripped up on nomenclature between different wiring diagrams while adding an A200 to my still-in-progress panel. The A200 has three types of audio output - a 4 ohm output, a 500 ohm output, and what they term "Detected audio" with no impedance description. Which of these should be routed to the audio panel (KMA 24)? I'm guessing the 500ohm, but it's just a guess...

Thanks for any help!

I don't have the A200 install manual handy, but my wiring diagram shows pins H and 7 from the A200 to the intercom.

Thanks - that helps a lot - that's the speaker output and is what I needed to know!

actually, H and 7 should be "Phones Out". See this doc:
