9+10) Bass + Trebble : These are used to adjust equalization level for this amplifier. Turning the knobs in
clockwise direction will increase LOW (HIGH)-frequencies, turning the knobs in a
counter-clockwise direction will decrease LOW (HIGH)-frequencies.
11) Input Level Control: These controls let you individually set the volume of the sound source that are
connected to the INPUT1, INPUT 2, INPUT 3, INPUT 4, INPUT 5. We recommend
to leave the control of the momentarily not used inputs at their minimal setting "0".
