It needed an audio panel to blend all the inputs but I didn't want to make room on the panel for a surface mounted one. It was a relief, planning wise and financially when my electronic guru recommended the Gretz Aero audio mixer, available from Aircraft Spruce for a mere 160 dollars. No voltage reducer needed. It fits inside the panel readily accessible(for initial set up) behind my right hand removable sub panel. It has worked faultlessly since.

Just a couple of further questions... What radio do you have that it feeds into ? I have read that the XCOM760 does not work properly unless with an aircraft audio panel - something to do with impedance .... or do you feed the radio INTO the Gretz and then from the Gretz to the headset ? The "range" of input/outputs suggest that it can do both. I guess the downside would be if everything goes through the Gretz and then to the headset, then if it fails, I would lose the radio also ... Thanks again, this is exactly the kind of thing I was looking for... I also have no panel space !

So I bought a dream panel. based around the G3X Touch with G5 back up, three axis autopilot, full ADSB etc. The radio is a Garmin GNC255 nav/com. There were five inputs into the audio panel - radio, SmartAss, transponder, EFIS and Nav, but space for lots more. The combined output goes to the headsets. I wouldn't worry about the reliability aspect - I think the components are mostly simple resistors that should have a near infinite life expectation. On top of that I see in the blurb that it says it is possible to arrange to have fail safe connection to your primary (radio) source.
