Radial Engineering MIX2:1

I use this mixer to mix 2 mono keyboard signals. There is absolutely no coloration of the sound and the attenuation in volume is very linear. The electric insulation is also very good. After a couple months of use the rubber "foot" has partially detached from the bottom, I guess the glue doesn't stick well to the varnishing. I would have given five stars if not for this, which I find not acceptable for this price.

I acquired a Radial MIX2:1 to use on a stereo FX output of my mixer and feed it into a spring reverb unit (that is a mono effect). Does the job perfectly and allows me to use the reverb on both channels of stereo synths. The build quality is excellent, built like a tank to handle stage use. Sound quality is great, transparent. The unit has a switch to use as a stereo to mono mixer and ensure that both inputs are mixed with the same level. It is the perfect solution for my use case.

I have 2 synths going into this and then onwards. Works absolutely fine. Slightly bigger than I thought it would be. Glad not to have another power cable to find a socket for.

I bought this to blend two mic pre-amp signals when tracking guitar cab and it works perfectly.
