Topping the master control section is the FAT Channel section. It provides four V-Pots™ and Previous/Next scroll buttons to quickly find and adjust effects parameters of all twelve auxiliary sends and 4-band EQ, compressor, and gate parameters for 48 channels - PHAT! A bright Vacuum Fluorescent Display (VFD) above the FAT Channel gives you visible read-outs of changing DSP values. (In addition to the optional SVGA monitor.) Although you can tweak the D8B's settings with its analog-style knobs, you may prefer the on-screen control panels for intricate adjustments.
