    Great Multi-purpose Mixer for Small Spaces!
    Summary: This mixer / mic combo is a real winner if you want to have a karaoke party, but also want more practical inputs for your audio setup! It takes a little playing around, but once you find the right settings there’s a lot you get for the money.Pros:- Very compact design: in order to save space, additional 1/4 inch jacks for inputs you might find on other mixers have been swapped out for a 3.5mm (1/8 inch) ‘Aux’ input and ‘Mic’ input, each of which have their own volume control. For most people who aren’t using studio equipment, this makes a lot of sense.- To this end, there’s also an RCA input which shares channel 3 and 4. To activate the Aux input, you need to toggle the button above that input.- Generally really low noise output (from 1/4 inch jacks, and the headphone port.) , provided you play with the gain and level knobs. I’d say the dynamic range averages somewhere between 50-60 dB.- That said, you still have a 1/4 inch output which is nice for running a balanced dual mono to XLR to my audio interface- There’s a separate Bluetooth input which is activated with the Mode button, and the sound is surprisingly clean. You’ll need to toggle the “To Main” switch to hear it, but it also has its own volume control- The XLR ports double as a dual mono Line In (left and right). Can you use them at the same time as the wireless mics? Yep! See my third image.- Channels 1 and 2 have their own level monitors.- USB-C power! I’ve tried this with a power bank and ports on my computer.Cons:- The RCA input on Channel 3/4 is pretty noisy if you use the included RCA to 3.5mm cable. This may be because it shares circuitry with the Aux channel but I’m not sure. It could also be because RCA is an ‘unbalanced’ signal.- Channel 3/4 does not have its own EQ sliders or an FX channel. This was likely to save space. You could patch channels 3/4 through to channel 2 though!- Nor does the USB / Bluetooth audio have its own EQ or FX channel. Not a deal breaker but something to be aware of- Channel 2 is used for both mics. I would have liked to see separate level monitors for each mic but it’s not a big deal for karaoke.

    Works great with my vintage Kenwood Receiver
    Only thing I had to get was two mono 1/4 x RCA patch cords for the main out to my Aux input on the stereo. Fun little unit saves buying a whole other Karaoke machine and this sounds way better pumping iPhone music mixed with the microphones for fun times! You do have to experiment a little with the buttons to get things set right but once you get the hang of it all works great. I powered it with a simple usb/ac adapter plugged into the back of the stereo.

    Sound management
    I must say from my last review, I found the problem I was having and corrected it. The unit now seems to be working well now. I think now it was an operator problem. There is still the problem of lack of instructions with the unit. The print that came with it, is so small you need special glasses to read. So now I feel I can use it as I want. I spend a good hour or more on it each day. Sorry for the bad review before.

    Good not great
    You can’t control the sound quality of the aux port. The microphone works and sounds great

    Where’s the Power Button
    Works well. But where’s the power button? I am unplugging the cord to turn off this unit. Help

  7. Amazon Customer

    Couldn’t be happier!
    I never leave product reviews! So the instructions it came with straight up suck. Especially if you have never had any type of mix board. After I had some help setting it up, it works great! I hooked it up to my speaker and my 75 inch TV for the ultimate karaoke nights!! The sound quality is great, better than some bars I’ve sang at. Overall very happy and would recommend!

    This item is really good!!
    This item is great value. Used it for my Zoom meetings and presentation and it has helped simplify my connections and setup. The mixer accepts a USB input which acts like an audio interface for my PC. The audio from the mixer can be sent to the laptop and at the same time, the laptop audio output can be sent through the USB to the mixer for monitoring!

    All you need in one unit
    Don’t need to buy mixer or wireless mircophone, just get this unit. Prefect for home karaoke

    DJ portable mixer
    Built in the Bluetooth, mixer and 2 microphones are good combinations. Works perfectly.
