I think the materials are somewhat misleading. I was wanting to be able to send signal from one deck to multiple amplifiers for different zones in my home, but that doesn't work. Also, the VU meters only work when I don't have any channel selected. Additionally, it seems to be introducing additional noise/static to the audio signal.

I use this mainly to switch between audio sources on my receiver which only accepts one audio input. I realize there are less expensive options to fit this need, but in addition to that functionality, it also looks really cool and has a remote. I have an Alexa powered universal remote, so I can use Alexa to switch between audio sources. Worth every penny.

All delivers as promised, yet two disappointments on the Bluetooth. 1) BT range is kinda poor, 2) to use BT, you have to turn the unit completely in order to connect to it. Just switching from aux to BT isn’t enough to make it broadcast. Not good for public use.

Really like the flexibility of this switching box it allows individual circuit paths to be quickly selectedI use it with my two guitars to select the audio input and the VU meters provide easy to read confirmation of the signal and the signal levelThe box allows the colors to be selected. I was not a fan of the ever-changing colors as I found that to be distracting, but I was able to select a static color to use.Overall, this is a versatile box for switching signals and allowing A/B comparisonsOne minor complaint is the three switches on the front panel are stiff and the box is quite lightweight so it moves when you press the switches

Got this to run my PC and a CD player to an Aiyima T8 pre-amp to a Aiyima A07 Max amplifier. All work flawlessly together. VU meters seem accurate with no delay and lights look good. Build quality is good for the price point. Switching between devices are simple and just work. Highly recommended.

Perfectly worked as an audio switching device for my turntable and cd player before the receiver. The VU meters are beautiful and functional especially because I noticed clipping from the CD player. I ended up going out of my headphone jack which had volume control or could have bought a -20db volume knob but this was a space saver. However, the meter helped me adjust my levels perfectly to match each unit's output and looks great too.Gave 4 starts because Douk Audio should include a power supply. This seems to be a common thing these days and it's getting annoying. USB plugs do not grow on trees! C'mon people, if you sell a product, at least include all necessary accessories to operate it!
