It is really great!
It's a simple digital recorder - the internal microphones are acceptable, and with external microphones, you can get different and probably better results.
It's not fair to say it has NO mixing capability, because initially, mixing audio was merely setting volume levels. So, you'll have to make sure you have your sound to your liking at the source. If your source material sounds good, then you should be able to make an acceptable mix.
Of course, you can always do better than this machine, but it simply is a great recorder with very limited functions.
My DP-02CF crapped out on me, and I bought this device. I like it much better. I like not having EQ, because it provides me a challenge to get a good sound. That's fun for me, but for some people, they might find that annoying.
It's sound is very good, and very neutral. I don't think it sounds as crisp as the DP-02CF, and that's good for me too, because I don't like crisp sounds. It's clear, clean and not over-hyped. Accurate.
It has two inputs, and that's handy, because you can record your tracks in stereo or dual mono, so if you're in a two-piece outfit, like I am, you can run one mic to one person and one to the other. Or you can get a mixer, and mix the drums on the mixer, and single-mic your other player. Very handy.
The internal microphones are really nice, and have very nice bass-response for being so tiny. It's actually nearing over-powering at times, but that is due to proximity effect. I bought it, haven't regretted it. Very nice sound. I enjoy working with it.
