Professional Audio Mixer, 4 Channel Sound Mixer With Dual Wireless Mic, Sound Board Console MP3 Bluetooth 48V Phantom Power USB Interface DJ Mixing for Home Karaoke Party Computer Studio Recording

The media could not be loaded. I was recently sent the DGNOG R4-Pro Karaoke Mixer for demo and review purposes, and I’ve been really impressed with what it offers—especially at this price point and form factor. Here’s a breakdown of my experience:Unboxing & Build Quality:The package includes the mixer unit itself, two wireless microphones, two mic anti-roll rings, USB-A to USB-A and USB-A to USB-C cables, a power brick, an RCA to 3.5mm audio cable, and a user manual. The microphones have a sturdy metal body with plastic battery caps and require two AA batteries each (not included). The mic rings are a nice touch to prevent them from rolling around, although they fit a bit loosely.Power & Connectivity:The mixer is powered via a USB-C port (5V2A), which is super convenient. There are plenty of inputs and outputs for various setups, and the instruction manual is surprisingly well-written and informative, helping you get things connected quickly.Mic Performance:The wireless mics connect easily and sound clear. I appreciate the physical Mic On/Off button on the mixer that gives you quick control. There's a dedicated gain knob for the wireless mic input—setting it around 10 o’clock gave me the best balance without distortion. Cranking it too high can cause clipping, so some adjustment is needed for the best performance. I have a background in Pro Audio, and although I typically work with higher-end Shure (SLXD, QLXD, ULXD) and Sennheiser (EW G4, EW-D, etc.) systems exclusively, I can definitely vouch that I was pleasantly surprised by the quality of these mics considering the price and form factor of this package. The fact that these are using the UHF band is also surprising!Sound Customization:The mixer includes a 3-band EQ (lows, mids, highs). The layout is a bit unconventional—the high frequencies are controlled by the left-most knob and the lows by the right-most, which feels unintuitive. That said, the EQ works well: I prefer cutting the lows and mids slightly while boosting the highs for a cleaner vocal tone.There’s also a combined FX knob that controls reverb and delay. Turning it up adds a spacious echo effect to your vocals. It’s not overly complex but gets the job done for home karaoke or small event setups.Use Case Tip:One cool setup I tried was hooking this mixer up to a car stereo system for a mobile karaoke session. Just use the RCA to 3.5mm cable and plug into the AUX input of your car—worked great for an impromptu karaoke night.Final Thoughts:Overall, this is a solid karaoke mixer with a great set of features: wireless mics, EQ control, USB audio interfacing, and decent build quality. The quirks (like reversed EQ layout and needing your own batteries) are minor trade-offs for what you get. There is a bit of background hissing sound, but it’s not noticeable once music or vocals are playing. Whether you're setting up for a party, event, or just home karaoke fun, the DGNOG R4-Pro delivers good performance and value.

I didn’t expect much from this small unit. Expected a total fail. Yet it proved to do the job and well. The wireless Mics and the bt work exceptionally well. I would go as far as to say better when connected to a dac it did not sound good. Personally thought bt sounded a bit brighter, not entirely sure if due to the source device or a little loss of quality during the digital to analog conversion. Either, way as most who gave good reviews i too had to find and dial in to the right tuning, as most who stated as much advised. Im not sure if my ears are become conditioned, but i feel the units sound improves with use, as if the circuits are breaking in, but thats speculation.Things i did notice that might be helpful to others.1. The manual only makes sense to someone that has experience with mixers. I suggest doing a small tutorial on how mixers work on YT. If not you will be turning knobs and pushing buttons and since some of us do connect it to our expensive theater systems, we don’t want the risk of damaging any components or speakers.2. Some people mentioned a hum. I’ve experienced it once. As if the unit was stuck in a sound loop. I unplugged and it rebooted fine. From that i learned the unit likes a certain order in which it is power cycled.Recommendations:I do not like that to power cycle you have to plug or unplug the c connecter. I found a dongle that connects between the unit and the power cord that has a switch. It is basically an external on off switch and gives me peace of mind not to damage the unit with constant un/plugging.I recommend using 1/4 plugs for the main out. It’s a better connection. Also recommend foam mic (wind) covers. I feel these mics sound warmer with.Lastly, always make sure the mics, and main volume are set at min before and after each use. Protects your other equipment.I hope this review is helpful. As a disclaimer, I cant speak on the recording or connection to pc functions, others have had different experiences, but for karaoke it performs very well. Although the manual is more a road map to what things do, it does make sense, unfortunately after you learn basic mixer operations.As a karaoke solution, 5 stars! Do not hesitate.Regards,-rb.
