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

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

Small footprint unit, about 7 inches wide, 4 inches deep and a little less than 3 inches tall including the feet. See the photos for the measurements. Banana plugs are best for rear connections. The spade connectors are difficult to tighten due to limited rear panel space and the inability to tighten the rear connectors securely enough to prevent loose connections with spade connectors. Setup is straight forward, it’s just a matter of running the wires for 2 sets of speakers (or amps) and making the connections. The remote is required to adjust the lighting on the VU meters. There is no On/OFF switch on the actual box, only on the remote itself. If you want On/Off capability on the box, Douk recommends that the user add a manual switch to the power cord. You can also plug and unplug the unit for on/off if you lose or damage the remote. I have been running this switch for months and I use it to A/B between a pair of Magico S1 and Zu Audio Soul 6 speakers. I know, it’s an unusual audio setup but with this Douk switch, I can really dial in my speakers based on the audio source. I cannot audibly detect any added noise or distortion from the Douk switch despite online reports of added distortion found during bench testing. From my experience, this switch works very well. It would be perfect with power on/off and VU meter light controls on the box but I still really like this unit. I have located a spare remote from the Douk website for $15 including shipping and it arrived faster than I expected. You will have to Google the Douk website and email them asking about a spare remote. I can’t include the URL/email here, Amazon won't let that occur. I suggested that Douk make a spare remote available on Amazon and they are considering that request. I found the folks at Douk very responsive and friendly! Otherwise, this was a great acquisition for my system, it greatly expands my audio system speaker capability and it’s well made. Hope that helps!

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.

良かったです。音もよくなった感じがした。(笑)
