FeaturesVU3 VU meter & audio switcher box is originally designed by Douk Audio:As a VU meter, with dual 60*35mm large meter, can dynamically decorate audio environment and provide incomparably visual effects when switching audio signals. As an audio switcher, easily to switch between two amplifiers and 2 pair of speakers, no need to plug in and out cables repeatedly to avoid wearing the contact point of the sockets.Powerful design and strong compatibility: all channels adopt fully isolation design, each channel's GND is independent without mutual interference. Supports all kinds of amplifier such as BTL / class A / class B / class D digital amplifier / tube amplifier etc.High-quality components to ensure VU3's best working performance:1. AC 250V 5A large current relay, easily to connect amplifiers and speakers with high power.2. Built-in large power load resistor with metal wire winding, each channel supports up to 300W power input and output.3. High-precision VU meter with peak LED display, and match perfectly with customized VU driver board.4. Fully isolation transformer to acquisite audio signal to avoid crosstalk from VU driver board, ensure clear and pure sound.5. Solid CNC full aluminium alloy case, large pure copper banana speaker jacks ensures minimum signal attenuation during transmission.Easy Use & Perfect Details: Powered by micro-USB 5V, with built-in protection load for speakers. With remote control, can quickly set the working status from distance. All settings can be saved after shutdown, more convenient to use.Proper size with exquisite appearance: cool black case, warm VU meter and clear indicators looks vintage and dynamic, can perfectly match with a variety of usage scenarios, very suitable for audiophiles who have more than one amplifiers or speakers.Warm tips: 1. For safer and faster delivery, the remote control may not include batteries (CR2025 3V), please prepare it by yourself. 2. Not connect VU3 to amplifiers whose actual output power is greater than 300W, or else VU meter may be damaged.3. When power VU3 off, Amplifier B channel and Speaker 2 channel will be auto selected and can input and output audio signal normally. And when power VU3 on again, it will auto switch to the channels that are set before.ParametersAudio input/output: 2 groups of banana femaleWorking mode: 2-IN-1-OUT / 1-IN-2-OUTAmplifier type supported: all kinds of type (BTL /Class A /Class AB /Class B / Class D digital amp / tube amp etc.)Max. through power of each channel: 300W (in actual)Backlight brightness adjustment: 4-level adjustment (can be turn off)Amplifier no-load protection: supportRemote control function: supprtSettings saved after shutdown: supportWorking voltage: DC 5V (above 1A)Power interface: Type-CBattery model of remote control: CR2025 3V (may not included)Diameter of VU meter: 60*35mmDimensions(W*D*H): 178*118*68mm / 7.01*4.65*2.68inPackage dimensions(W*D*H): 280*185*155mm / 11.02*7.28*6.10inNet weight: 980g / 2.16lbPackage weight: 1.2kg / 2.65lbPacking List1*VU3 VU Meter & Audio Switcher1*Remote Control(without battery)1*USB Cable1*User Manual

This is a really excellent compact 2-way switch and vu meter, nice looks and good quality (it comes in a metal case). It’s great if you have 2 amps but want to put them through one pair of speakers (or two), like myself. My only gripe is the remote control, the quality of which is terrible, really flimsy plastic. Mine cracked as soon as i opened the battery compartment.
I would also recommend getting banana plugs for the speaker connections – just connecting the speaker wires to the screw-in connectors is very finicky given these connectors are very close togther.

Good finish and good product, it is exactly as advertised. I’ve had it for a month and it’s working perfectly, connected with two sets of speakers and two amplifiers.

All items received in good order as described

a small “just for fun” thing – so it’s an expensive extra flasher – the exact ones would ideally be built into your tubes & expensive amplifiers + + more accurate ones can be obtained for a few hundred more 🦉🔚
