what is dsp mode
The DSP modes are usually the receiver's own surround moves. Dolby Pro Logic is from Dolby labs. I tend to use Dolby Pro Logic II when I want to matrix a stereo signal. I'm not a huge fan of DSP's from receivers.here are two types of surround processing in your receiver: ambience extraction modes (DTS Neo:6, Dolby Pro Logic II or II x) and ambience generating modes (Hall, Club, Stadium, etc).
