It sounds like you want to add a change-over switch to connect the P2 headset phones to a separate source input (iPhone headphone output etc). As Rainier says, disconnecting one headset's phones from the V16 audio output will make no difference to the volume levels due to the low impedance of the ou...

Is the Fuel Level Pull Up resistor enabled on the DIP switch?

Since no one is responding to your post, I'll chime in. The only audio out from a V16 is the headset drive on pins 1&2. This drives both headsets. Assuming you have dual plug comms, you could make an 'intercept cable' with a male-female 1/4" jack pair and tap off to a suitable connector for your rec...

....also, the capacitor value usually needs to be a minimum of 22,000uF 25V.

Try significantly reducing the mic gains on both P1/P2. -12dB might be a good starting point.

Yes. The principle is that if you also ground the jack socket, say, to the airframe, you will create a ground loop which can cause many issues.

Right side only I believe.

Pleasure. Glad to hear that it's resolved.

Have you adjusted the microphone gains for your headset(s).
I found that it needed significant attenuation of -12dB or more for A20 and Zulu 2.
Without doing that receivers will hear significant compression/limiting and possibly distortion.

On a similar note, I've been designing a gauge for fuel pressure and run into more issues.
A gauge and a text value both driven from the same RDAC FP source show different values under simulation (but they do change with the slider)....?
Anyone else seen this?
