U31 3 Way RCA Audio Switcher, Stereo Audio Switch Selector Box

Used the SOLUPEAK U31 for a short time while awaiting Delivery of some Audio equipment I had out being modified. Build Quality was Quite nice, far better than other switch-boxes I've owned before. In use, it was audibly invisible, having neither additive nor diminishing sound quality. ~{exactly what was desired). Though not needed or being use curently, I will keep it handy for possible future use.

Works well so far! I wanted to switch between 3 different outputs from my DAC at a reasonable price-to-quality ratio, and I have been pretty pleased with this Switch Box. The sound quality has been good with no noticeable sound degradation with any of the three outputs. The build quality seems quite nice and robust all around. The RCA ports feel solid as well. Lastly, the dial to switch also has a nice feel and weight to it. Really happy with this so far.

I needed a way to switch the input to my subs off. Nice size and feel.

this is a solidly built device that does exactly what it says it's going to do: offer three-way switching. A few months in and I haven’t had any failure points with light use.

So far so good. Does what it's supposed to do, does not affect sound quality. Seems like a quality built product.

Junk. The RCA connectors do not properly retain a cable. DO NOT BUY. Some will complain of "noise" with this box and other similar ones. This is because the RCA connector is not standard and undersized. The connector will not make a proper friction connection with the ring of the RCA cable. Intermittent connections lead to issues like noise. This device is junk. None of my proper studio or home gear has this kind of problem. Just this junk.

It does what is intended, but it leaks signal onto adjacent channels. Most of these switches do, but this one is quite noticeable. If you are using it in a studio or setting where this switches an input signal between multiple amplifiers/outputs that stay hot all the time, you may have detectable audio output on more than just the selected system. While it is very quiet, it is there and can be heard. I use it in a setup where only the selected amplifier is powered up so it's not an issue for me. It is, however, all metal and fairly well made, but the selection knob does have a little up-down/side-to-side play in it. The knob is connected to a shaft/rod that turns a switch on a PCB that is mounted to the back plate of the switch housing. It was done that way to eliminate the need for wire, but would have been much better quality if the switch was mounted on the front plate and wires ran to each input/output instead of using a PCB. This would have eliminated pretty much all signal leak, but wire is expensive, of course.

Seems solid but have to wiggle the switch to get connection between channels. That sucks. Also the indicator line doesn’t line up quite right with the numbers.

Ideal para hacer el cambio de amplificador a receptor av para un único subwoofer

Ça fonctionne

Surprisingly well made from good quality parts and performs faultlessly. Well worth the money.

音色を変えることなく、本来の役割をしっかり果たしてくれています。満足しています。

Ich habe mithilfe des Schalters mehrere Aux Quellen an meinen Streaming Verstärker angeschlossen, der nur ein Aux Eingang hat. Es funktioniert sehr gut; beim Umschalten zwischen den Quellen keine Geräusche und ich kann auch kein Übersprechen oder Brummen festzustellen. Ich denke auch die Wiedergabequalität hat nicht gelitten. Das Gerät ist sehr ordentlich verarbeitet und macht einen wertigen Eindruck. Ein kleiner Nachteil, das Gerät ist sehr leicht und wenn man hochwertige etwas steife Kabel anschließt, steht es nicht ganz so sicher.
