Connecting multiple sources to 1 set of amplifiers, cheaply

Post by claz »

Hello, I have multiple sources that I'd like to connect to one set of tube power amplifiers.

I'm looking for a recommendation for a cheap and transparent source selector or aggregator, nothing fancy.

I already have a volume attenuator before the amp.

Most of the sources output via RCA cables (CD, LP, radio -- 5 total), so something that supports that natively would be ideal -- but I'm open to suggestion.

Is there any reason not to do this with multiple RCA-splitting cables -- but in reverse, so that all the Left channels eventually come down to a single left, and all the rights to a right?

Or a budget preamp? I'm hoping to stay in the $100 range, as I don't need a phono stage, and I don't want wireless connectivity.

There are various products on Amazon that purport to accept many RCA in, with 1 RCA out, but I'm somewhat suspect of their quality, perhaps unjustly. Hence my asking here.

Thanks for any thoughts.

I've used varieties of the 'Amazon' type multi-switchers on many occasions without issues.

You should be able to get one that works fine for about $10-$20...

... non-switched splitter cables are both cumbersome and unnecessary - and could cause audio quality and potential damage issues. Switcher not splitter! :)

A cheap mixer, like this for example: https://www.gear4music.com/PA-DJ-and-Li ... -Mixer/2A8 , and some RCA to 1/4" jack converters like this: https://cpc.farnell.com/pro-signal/psg0 ... XcQAvD_BwE should do the job.

Ignore the post count, I have no idea what I'm doing...

Without some sort of attenuation, line level sources going straight into a power amp may be very loud!

Looks like that’s already taken care of.

Reliably fallible.
