When adding the GPS (stereo) audio, do the GPS audio outputs wire directly to the headset jacks in parallel with the comm ouput wires? And when you're using stereo headphone jacks do you just wire the single comm audio output to both jack pickups? I can't see how else you could do it. In my case it's a Garmin SL40 com and Garmin Aera 500 gps. Thanks in advance.

Does your system include any sort of audio isolation
or mixing amplifier? The legacy approach to merging
multiple audio sources into the head-set feeds uses
a mixing amplifier. Here's and exemplar device
that includes some variations on the audio system
architectures.

Here's an alternative: i assume you are a single seater 'warbird' and have no intercom.

Connect your comm output and each of the two Aera outputs to 150 ohm resistors. Connect the other end of the three resistors together and connect this point to your headset earphone.

Thanks, Vern Little

Fortunately at the moment nothing is hooked up and I have no amp installed. The radios (Garmin SL40 transceiver, GTX 327 txdr with Ameri-king encoder, Aera 500 GPS) are mounted, as are the headphone and mic jacks and the four PTT's. There will be an intercom, two position, PTT activated, using the one built into the SL40. Two hole open cockpit biplane. No audio panel.

Open to suggestions!! Shocked

Correct me if I'm wrong Bob, but didn't you used to offer a little $20-ish audio amp just for this type of situation? I recall buying one and squirrelling it away for the day when I might need one...
