Douk Audio VU3 デュアル アナログ VU メーター, 2 ウェイ アンプ/スピーカー スイッチ, DB パネルディスプレイ オーディオ スイッチャー ボックス

音のセパレートもよくメーターのフレもツマミの調整によりしっかり振れています。 中々良い商品だと思います。 何よりリモコンによる切り替えが出来るので比較時は重宝します。

本体側の電源オフがアンプセレクトボタン長押しとちょっと分かりにくい点を除いて大変満足です。

昔のアンプのような雰囲気が良いと思います。

私なりには十分満足をしてますが（昭和の古い人間ですから）若い人から見るとメーターの針が触れているのが分かりにくいと思います。

アナログな感じがとても良い

電源を入れなくても、前設定で音楽が聴けます。

電源が別売となってて、全然疲れない。

メーターの感度もいいし大きさもちょうどいい値段も手ごろ。

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

Pleasantly surprised by the quality and utility. It allows safe switching between two amplifiers and two sets of speakers. I was expecting a noticeable decrease in fidelity, but no, it appears to pass an honest signal. The remote is really necessary and it works well, although it is a thin plastic, I dropped mine on a concrete floor and had to re-build it. The box itself though is well made. I did not expect to find this as useful as I did.

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.

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.

As an amp and speaker switcher it works well for letting me try and compare components in a live a/b test setup. For the meters the light looks incandescent and matches with vintage gear well, and they dance nicely with the signal if that is all you wanted. Some say this reduces signal to noise ratio, and it might but I can’t hear it in any of my setups.
