- 3) You bet. This thing is designed for multitrack digital recording. Each
- channel will have independent volume, panning, etc. Of course, the sample
- rate will probably suffer as you go for more and more full-frequency output.
- A single stereo pair will be capable of 50KHz playback, but when you do
- 8-channel mixing, you might (I repeat MIGHT) be limited to 25KHz/channel or
- the like. I don't know all the details on the DSP.
