Audio panel/ intercom
 
I'm adding an additional common to my RV6. I am looking for a simple intercom and audio panel for two radios. I don't need Nav functions etc. Just radios and perhaps music inputs. Any suggestions?
Thanks

Maybe a Garmin GMA240? It?s a great unit, works very well.

You can also use a Standard Intercom like a PM1000II and a toggle switch to select between both radios.

I got PS Engineering's PAR100EX. It serves as my intercom (2 inputs), plus has a built-in VHF (my Comm 1). It will accept a second radio, which in my case is my SkyView VHF (Comm 2). It has audio inputs that allow my wife to patch in audio from her Ipad or phone, and I can sequester her audio to her alone. We can do the same with it's Bluetooth. As you wish, it has no nav inputs.

PAR100EX has been replaced by their PAR200A:

It only takes up panel space for one component. The transceiver is a seperate satellite component: I installed it on my subpanel out of sight but easily accessible.

Love it! :cool:

Do not try this, it never works very well. You will not be happy with the results.

I have to respectively disagree here. It may not work for everybody, but I've been using this method for over 20 years and am very happy with it.

The toggle switch must switch both PTT and Mic audio.

As a retired EE with good credentials and deep electronics design experience, I'm with Mel on this one...there are several ways to setup two COMs without an expensive audio panel.

My latest favorite, especially if you have to buy a intercom, is to use the Dynon intercom and switches. The Dynon has separate audio inputs for two COMs and a NAV if needed. Then you use a 3PDT COM select switch and a SPST both select switch. That's less than $10 plus the cost of the intercom.

And I understand Mike H's comments and concerns as you will probably get poor results if you don't have some sort of summing amplifier (internal in the Dynon mentioned earlier) for the audio signals...

Send me your email and I'll email a schematic.

+3 I use the intercom plus switch method and I'm happy, and I have 2 coms plus one VOR, plus various warning tones, and music. As noted above it is best to have separate inputs for each radio or other audio source.

Actually, since you don't have to listen to 3 morse codes and marker beacons and stuff anymore I think the traditional audio panel is going extinct. I just threw away a couple king KMA's (along with a Pioneer Superscope).

I like your idea Deene!
Is that the SV 2S? Maybe their comm would work too.Please email me at algrajek@msn.com
Thanks
