Title: Need tiny amp to make stereo signal from computer to mono speaker
Post by: secret80sman on January 24, 2013, 10:16:00 pm

Guys, I am restoring a Ms. ac Man cabinet and want to run the audio from my MAME computer into the single speaker installed in the cab. Since some games have stereo sound I need to know what to do to sum the signal so it won't be out of phase for mono games but so both left and right sources are equal in the mix for stereo games even thou I know I won't have stereo sound anymore.

If there is a tiny amp I can mount in the marquee box for this purpose that would be great. Even a little PCM type I could nail down or similar arrangement would be acceptable.

See this thread regarding mono output:

Then just get a cheap mono amplifier kit:
