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.

Bass Performance: The frequency response starts to dip around the 45-50 Hz range, which is pretty much the lowest point for most karaoke tracks. For 99% of karaoke songs, this range is more than enough. The bass sounds great! I tested it with both Bluetooth and wired connections for music playback, and I’d say the sound quality is slightly better with a wired connection.Experience: The battery compartment is a bit tight, so removing the batteries can take a little effort. I’d recommend using scissors or another small tool to help get them out more easily. The microphone has a faint background noise, but it’s barely noticeable and much quieter than the music itself. Honestly, almost every audio device has some degree of background noise; it’s all about managing it properly! Initially, I had some issues connecting the device, but after reaching out to the DGNOG team, they not only helped me resolve the issue but also shared some helpful insights on audio equipment, giving me a whole new perspective. Their support was fantastic!Suggestions: Although the user manual provides a detailed connection guide, I’d suggest reaching out to the supplier if you encounter any issues during setup. Misconfigurations could potentially damage the speaker or other connected devices.Pros: Affordable price, low latency for karaoke, and it has a knob with a slight center detent for stability. It’s compact—just a little longer than your hand. High frequencies reach around 17.5 kHz, which is completely sufficient for Bluetooth music playback, especially from streaming platforms like YouTube.Conclusion: Simple design, focused functions, and no unnecessary features. Personally, I think an RCA port for the main output would be preferable over the 6.5mm jack. Overall, this device is perfect for family gatherings, karaoke, or even small venues. Highly recommended!

OK, so the price is good if it is a unit that does the things it says it does. When you get it to work, it is very cool. My primary usage is to play a music track via bluetooth (BT) while I have the wireless microphone on to sing along. Getting BT to work is not likely unless you figure out that you'll need a 2A power source.Before being informed of this requirement, I found that when you turn the unit on, the BT display shows "HI" and then blacks out. Pressing the 'Mode' button won't do anything if the 'Mic On' button is depressed. If you turn off the 'Mic On' button the BT screen is still black and doesn't change when you hit the 'Mode' button. Instead, you'd have to power off the unit (via disconnecting the power cord because there is NO power switch!!!) and then, if the 'Mic On' switch is off, you can turn on BT.Regarding output, this unit is really for a home usage situation because a professional will have a much more impressive mixer. Not many home users have an amp or receiver with 1/4" mono input jacks? You may be thinking that you can use the 'Rec' RCA output jacks on this unit to connect to your receiver. After all, one of the pictures on this Amazon page shows "RCA or 4/1" connected to a "Home Threat Setup" (yup, made in China). No, connecting the "Rec" output to my receiver sounded like $#!^. I had to purchase 1/4" - to - 1/8" adaptors and then 1/8" - to - RCA cords. Pretty messy, but it works.And finally, the microphones. They work well, look nice and sound nice. Just don't leave the switch on for a few hours or you will kill the batteries. Probably not a bad idea to have some auto-off functionality in the event that the mic doesn't pick up any noise for some period of time.Update:I've been using the unit regularly for 6months and ended up being totally happy with the unit, Unfortunately, one of the mics just died. I'll post the outcome of this problem.
