It's the same general idea, but smaller.
Basically, multichannel recorders with mixing and mastering capabilities have two different major numbers that you can check. The first is how many parallel channels they can take in. That Zoom R8 has two channels in (or one stereo channel) while the Tascam I have has eight (or four stereo).
The second is how many channels they can handle in a mix, and the Zoom there has a quarter the capacity of what my Tascam has. The Tascam also has a rather nice set of options for Send and so on - for about double the price of the R8.
I'm not saying that the R8 is bad; don't get me wrong. I'm saying that there's more overall power in the DP-32SD and more bang per buck as well. Both Tascam and Zoom have bigger and smaller options than the R8, down to jacket-pocket battery tools and up to the DP-32SD, which is the flagship. Then there are closely related tools that don't do as much for you in finishing terms, but will record live performances, such as the Zoom LiveTrak L-20 or the Tascam Model 16.
