An external mono switch

[Paul Ebert]

Here's a (possibly embarrassingly) simple question. How do I build a mono switch?

I'm designing some speakers and I'm tweaking the crossover on the one of the pair that I have gotten to the point of being able to do so. So I'd like to feed it a mono signal, but my Pearl has no such feature.

Can someone provide me a circuit I can put in a little box to go between the preamp and the amp for this purpose?

By the way, the Pearl is absolutely fantastic.

Take two resistors, each of which is about the rated load impedance
of the source, usually 10Kohm. Twist them in series and connect each
end to the two channels. The center twisted connection is your mono.

Thanks, Nelson. I really appreciate it. Time for an RS run!
