Rolls MX41b 4-Ch Passive Mixer is rated 4.25 out of 5 by 4.
Rated 5 out of 5 by from Amazing!I bought one of these to increase the inputs on my keyboard amp. I was pleased to find that with two synthesizers plugged into it, there was no signal loss. Not sure how they do it, but this is a great concept, and one would be hard pressed to build one for cheaper.

Rated 3 out of 5 by from good tool to have handyBecause it accepts stereo channels, it could probably be used for balanced signals. There are warnings though about not mixing stereo & mono (i.e., use all stereo/balanced, or all mono/unbalanced). On my unit, the 2nd slider does not move smoothly and easily all the up to the top of it's spot. I have to kind of force it up the the top. (That's just bad quality control). Otherwise, it works just fine. Connectors are good. I also like that it is manufactured in the U.S.A.

Rated 5 out of 5 by from Excellent device for an old designI needed to combine the signals from the left and right channels of my stereo to create mono without damaging impedance. RCA to 1/4" adapters in and out, an Outlaw mono amp and Energy LCR speaker and I had something from the old days: 3 channel stereo. Left, right and mono center. I think Klipsch did this some time ago. Works great.

Rated 4 out of 5 by from Works just like it shouldI had a hard time finding a small mixer with mini inputs to combine several computers on the workbench into one set of speakers. This does exactly that. So all I need to have on had are mini-to-mini cables. No more adaptor conglomerations and only a small amount of desk space used. I'm not using this for any quality audio so I can't comment on those features but it seems to work just perfectly.
