2-channel amp to mono for a Center Channel speaker?

Do It Yourself

hi,
Is there a way to us a 2-channel amp (Adcom GFA 535) to power a center channel speaker with one set of binding posts? There is no “mono” switch on the adcom.

Thank you!

Yes, you just use one channel, e.g. left rca in and left binding posts out. WHATEVER YOU DO do not join the output of both channels of the amp together (you’ll destroy part of it).

I’ve just realised that I may have misunderstood what you want to do. I assumed you have a HT preamp that’ll output a centre channel line level signal. If you were hoping to just join a normal left and right channel to create a centre channel it’d not sound any good if it’s the sum of the two channels.

I assume that you are using an AVR or processor for line level signal, if that’s the case then you can use one channel of the amplifier to power the center channel.
