D Debra M4 Mini Audio Mixer Mixing Console Mixer Sound 4 Channel with Sound Board USB Bluetooth Audio Interface Mic Preamps 48V Phantom Power Mixer Use for DJ Studio PC Recording Singing Webcast Party

Updated on 1/13/22: I've had it for about a month. It is an amazing machine if it lasts. It does everything I want and it does it pretty well. It is easy to carry around. It operates on any 5v USB port. Not like Behringer mixers you have to use their own big old 12v power supply with a funky port. The quality of recording is only so-so. It failed on me once and I almost returned it. I wanted it to work and I waited for a few days and it worked again. Earlier today, it quit on me all of a sudden. It doesn't read USB drives. It reports a proper Bluetooth connection with my phone but it produces no sound. I am returning for a refund.My original review: Cheap but functional. It is easy to use and the sound is not that bad. The look and built are quite good. It exceeds my expectations initially. The main problem is durability, which I've heard complaints about but can't make prediction for the one I have. If breaks I will edit this review and let you know.

I use it primarily with our Sunday service live webcast. I interface it with our main mixer where all audio devices(mic, guitar, organ) are connected. Link the mixer main out to M4 mini in and OBS detected M4 mini as my main audio device and the audio quality is awesome.

I connect this device to my macbook via USB. It will work well for the first few songs but after a few playbacks/ songs, it would have intermittent connection with the macbook.

The media could not be loaded. The mixer board performed well but after plugging and unplugging the USB power, the port fell off. It lasted about 5 months being used 3 times a week

Did not come with all cords needed to connect to PC.

I've been using this for about a month now and it's very nice for daily and amateur use. I primarily use it to map all of my guitar output to my computer or my headphones so I can record or practice without disturbing my neighbors. One downside is that it doesn't support playback through the headphones while recording, so if you're interested in multi-tracking I suggest finding another way to monitor your guide tracks. I've managed to use windows settings to pipe it through a pair of headphones but the latency makes that option a nonstarter. I'm trying to figure out an AirPod-tucked-into-headphone workaround but if this is sounding like too much of a hassle for you I suggest upping your price range and seeking an option that can support two-way audio.

I bought this mixer to record voice overs for a small radio station. It works in Analog and Digital with a USB connection. I can use it on the go, very compact.
