I am wanting to combine Garmin GDL52 XM music (stereo) and Aera 660 alerts (stereo) using a passive mixer to the music input on a PS Engineering PDA360EX audio panel.
NOTE: I cannot get to the back of the audio panel without removing the panel.
I am looking for guidance as to the size of the resistors that must be installed prior to mixing on both channels. Any help is appreciated.
thanks
