Review: Great mixer. - Very impressed with this mixer sounds fantastic. Bluetooth works great. MP3 player works great only one delay, but it sounds very good. i’m using it for my band running stereo guitar. i’m using it with a sound town amp. I just got which is also amazing blows away the crown. vocal sound great.
Review: Surprisingly good. Reliable, sounds great. - I am a pro audio professional. I work with bands and DJs. I know that sound town is not really a respected “pro” brand. It’s kind of “cheapo”. Like Gemini or American DJ or something like that. But… I just needed something in my little test rack that i keep just inside my garage door so I could plug in and quickly test speakers as they came back from each gig. It didn’t have to be great. It just had to work. I have to say, that I am actually very impressed with how this amplifier sounds, considering how small it is, and how reliable it has been so far. I use it for testing everything from subwoofers to stage monitors to full range speakers. I even use it to test out active three-way larger PA speakers so each channel is doing a separate frequency range, I.e. external sub channel 1, lows ch2, mids ch3, highs ch4. Not only does it do all of this without any issues, but it seems to be loud as hell with plenty of headroom. I haven’t taken this to a gig, because I use QSC and Powersoft for the real gigs, but this little amp is worth a look if you are a small DJ or band on a budget. It’s actually hard to believe how much output this thing has while still being small enough to put in a backpack. Amazing.

### ⭐⭐⭐⭐ Good Buy
*by C***S on March 19, 2023*

I was looking for an option to run passive speakers when I didn't have my actives with me, as well as more than 2 channels. This amp has plenty of power over 4 channels. I would buy it again, if I needed to.
