Douk Audio VU3 Dual Analog VU Meter, 2-Way Amplifier/Speaker Switch, Audio Switcher Box with DB Panel Display

The Unit is overall good, looks good, there is a peak indicator LED which i felt was not required, the other draw back is the the swing indicatore needs to be adjusted every time you increase the volume. The cost of the unit is on the higher side could have been lower.

Quite expensive and there's no black Dail or white dail option available. Backgroud multicolour lights look very cheap chinese toy type.

muy bueno para quien tiene dos pares de bocinas y quiere cambiar entre ellas sin pérdida de sonido. lo mismo con dos amplificadores, ideal para pruebas A-B

非常に使いやすくて重宝しています。

Unit worked great out of the box. You need your own USB power adapter because none is provided. Pretty much any old USD power adapter you have lying around works. This device is beautiful eye candy for your stereo setup. Who doesn't like 2 lively VU meters dancing on the music? I love the dial where you can select the sensitivity of the meter, so that even at low volume your meters can be dancing wildly. Minor gripe is that no battery was included for the remote but luckily I had one lying around. I tried a CR2025 but it needs a CR2032 battery. Although the remote control is a smaller than credit card sized piece of cheap black plastic, it works great. There is no discernible impact on sound by putting this unit between your amplifier and your speakers. Perhaps a little bit more rolled off on the high frequencies but I might imagine that. This device is great for A/B testing of speakers and amplifiers. It is amazing how smoothly it switches between speakers and amps. I was totally expecting loud clicks and pauses in the music but it is completely smooth and pretty much unnoticeable. Quite amazing. Obviously you need (an) extra set(s) of speaker cables, depending on how many amps and speakers you want to connect. The unit is much smaller than you would expect from the pictures. Those pictures are doctored where the unit is enlarged and showed on top of regular sized 17" wide stereo equipment, looking like almost equal width. That's a nasty marketing ploy. Not cool! The actual unit is 7"x5"x3". If you scroll down deep enough into the small font area of the manufacturer's description they give you the actual measurements but the pictures are totally misleading. Nonetheless good build quality and everything works as advertised. It's a keeper!

I love music. I also love colourful lights. This product adds a cute, compact retro vibe to your existing stereo. The VU meters have a pleasant glow, and the red needles move hypnotically as the signal strength changes from your stereo input. Hooking up the box was straightforward, you can use either the wire-on-post or banana plug system. It uses a low wattage USB power supply, which plugs in simply to your amp (if it has a bonus AC out) or to the wall. You have to supply your own USB wall brick, but hey -- we've got all drawers full of them. The VU box itself doesn't seem to make any difference to the sound quality, although purists may disagree. I'm a middle-aged dude with tinnitus so I'm not too picky. The only issue I have with the VU box is the sensitivity dial. Don't get me wrong, it works great. But you have to adjust the dial depending on the volume or sensitivity of your signal input -- or the needles don't dance around properly. Loud CD? Needles will slam. Quiet vinyl? Needles won't move. It would be nice if this had some kind of auto-attenuation feature for the input signal, but hey for less than $100 it's pretty cool.

Excelente equipo, funciona a la perfección y no distorsiona el sonido original, tal vez las instrucciones no son muy claras tuve que buscar en internet sugerencias de conexión. Lo recomiendo totalmente. Excelente calidad en su funcionamiento y acabados premium
