How to play music through (only) the center speaker?
I just picked up a used center speaker, and I want to test it out to make sure that it's working properly. Normally, I'd have everything go to the correct channel, but while testing, I'd like to downmix stereo music sources into just the center speaker.
Normal music playback goes though the left/right channels.
The setup is:
PC -> HDMI -> Marantz receiver -> 3.0 speakers
