The MDR1688 is a true professional 16-channel stereo
mixer. Connecting all your microphones and instruments
to this mixer is simple, with eight mic/line inputs plus
four additional stereo channels. There are also dedicated
stereo effects returns for the on-board digital effects,
which are both numerous and impressive. The MDR1688
features 256 digital studio-quality effects including
delays, chorus, flanging and lush reverbs, which can be
added to your vocals or instruments using the built-in

The mic/line inputs feature a 3-band equalizer with
