Hi Paul,

I highly recommend that you do not try to connect 2 devices to one speaker.
It could damage one or both of the instruments. I have done repairs to
several soaring instruments which had their audio output circuits fried by
doing just this.

I am wondering if it is possible to combine the outputs of a vario and a
radio and send it to one speaker. I did try to Google it, but I did not find
a satisfactory answer.

Any ideas please?


Cheers

Paul

Yes, one does need a mixer or audio panel. Not a bad idea though. If all the electronic noisemakers ran their output through an audio panel, sound levels could be "equalized" and it could have a master volume. Using one, larger speaker with good sound is better than a bunch of little crappy ones.

We would need a special unit for gliders. Airplane units are too big and intended for headsets.
