Overall, a versatile tool, appears to be well built of quality materials. An amplifier with extensive input options and onboard signal processing. Steel chassis, solid feeling controls. Machine screw assembly, solid feel to the power rocker switch, and a fuse (unspecified) in the IEC power connector. The LED displays are bright.Input strips have hybrid ¼”/XLR inputs, with input Gain control, and overload indicator LED. Each strip has an optional phantom power. Three bands (Low/Mid/High) of EQ. Pan control to sweep from Left/Right (and in-between), and a smooth slider to control level sent to L&R Mains. Each strip also has a send for an “FX” bus and a mute switch.The FX section of the mixer has dozens of options for digital reverb, delay, distortions, signal processing, and a seven band graphic equalizer the level is controlled by how much of a strip you SEND, and how much of the FX bus you return, to the overall mix.The FOURTH strip is selectable to operate EITHER identically to the first 3, or as the input for a USB drive/MP3 player, or the Blue Tooth receiver. The Bluetooth connected to my phone just like every other device.The amplifier section is two channel (stereo), and has 4 outputs, two each of 1/4” or twist (speakon) type for left and right channels. The documentation specifies 250 watts at 4 (FOUR) ohms for each channel, but the mixer is not marked. Most speakers in the US are 8ohm. Buyer beware. I know that the amplifier just pushes a little harder for the higher load, but I would not assume it’s strictly arithmetic (125 watts), Besides I never run an amplifier at full load. If your speakers are rated for 125watts at 8 ohm, I don’t think you’ll risk damaging the speakers, but I have no opinion as to damage to the amplifier by pushing the 8ohm load. The fan is fairly quiet.The shipping container claims that the unit is listed with “CE” (the European safety agency, equivalent to UL in the USofA), but there is NO marking on the product itself. so I wouldn’t leave it plugged in unless you are sitting with it. The container also claims “FBQ feedback detection system” but I found no evidence of it on the EX4 unit.There was no “noise” in the operation of any knob or slider, but there was a transient (pop) when actuating the phantom power option on the input strips. And there was a slight hum (at about 127cycles) associated with the phantom power circuit on two of the strips. So I suspect this is a workmanship problem, or it would have appeared on all 4. Also, if you just select the phantom power (on or off) before you power up the amplifier, it’s a non issue. The hum was not noticeable when there is signal on the strip.The documentation that was packed in the shipping container did not match the product I tested (EX4), and I could not find any documentation on the internet for the Kashun EX4 mixer/amp.You could have a great three (or less) singer Karaoke rig, using the onboard USB (or bluetooth) player. Even dial in a little reverb the “help” the singers. It CAN be used with powered speakers, if you use the UNPOWERED outputs on the top surface of the unit. Really a versatile design.

Works good

I used this for an outdoor acoustic set last month and it was great! Sounds very decent, great I/O options for audio in and out, worked great with my buddy's speakers. The reverb and delays sound really good and there are tons of effects in there, I imagine this could be a fun interface for someone who only has a basic usb interface with no onboard FX or faders. Honestly packs quite a punch and surprisingly good for the money!

This is the third mixer I have purchased. The overall construction is great and you can tell by the weight of the mixer that it is made of quality materials. The sound quality is great and works well with our main sound system, no pops, static or breakups were heard. All ports work as they should and Bluetooth is connected. Knobs, buttons and sliders. The knobs feel smooth when you turn them, and while most people don't like the friction when turning them, I find it useful as it prevents human error when adjusting the volume. As for the buttons, they have a nice tactile feel to them, clicking when pressed and having a bit of a kickback. The sliders are nice, smooth, and light. The only thing I'm most pleased with is the effects knob, as it has a clear stop position and gives me a clear view of the machine. What I like most is that the machine also comes with its own amplifier. All in all, for the price and quality, it's worth your money, whether it's a podcast, karaoke mixer, or even a church.

Needed to replace a powered board, but didn’t want to spend a lot of money since I don’t use it very often. This board is perfect for my use. Everything I need, plus plenty of power and more controls than I typically use. The only negative is just the size and weight. It is quite bulky and heavy compared to other boards.

If you follow directions and run 4ohm speakers this mixer is a beast. If you hook up 8ohm speaker mixer will start to shut down because it was not made to run 8 ohm speakers. Mixing mic or adding echo or any of dsp effects, it works perfectly.
