You have 3 MEMORY settings to program your own settings (MEMORY 1,2,3). Select SET

Here is my EQU setting:
80Hz +3bars, 500Hz +2 bars, 200Hz +1 bar, 1kHz (flat), then +1, then +2, then +3 for the higher frequency.
ECHO (no bars)
ROOM (no bars)

Then, hit the AUDIO button to set the BASS & TREBLE.
BASS +1 or +2 to the right
TREBLE +2 or +3 to the right.
FADER middle
BAL middle

Good luck.
