Active Input: Low sensitivity input for instrument with active circuitry and high output.
Passive Input: High sensitivity input for instrument with normal output i.e. Passive.
Allows access to the different pre amp modes. Pre amp mode selection is achieved
by depressing the relevant switch. With no switches depressed the unit defaults to FET. To access both FET and Tube
pre amp sections depress both switches simultaneously.
Sets the level of drive in the Tube pre amp circuit. Should be used in conjunction with POST gain
control to achieve the desired sound. To achieve a clean sound set the PRE gain level low whilst setting the POST gain
relatively high. To achieve a saturated pre amp sound set the PRE gain high and the POST gain relatively low.
Sets the level of post gain. See above for application.
Two factory set PRE-SHAPES are available. The MID PRE SHAPE produces an overall dip in the mid
frequency responce of the amp whilst at the same time boosting the low end of the amplifier. The HI PRE SHAPE
boosts the upper end frequency response of the amplifier. Both these PRE SHAPES can be selected simultaneously to
provide a third factory pre set. These pre shapes can be further modified by the units BASS, MID and GRAPHIC EQ
sections. PRE SHAPES are footswitchable on all models except DB150C and DB150H.
Controls the overall bass response of the amplifier
Nine band GRAPHIC. When switched out the EQ will be set in a flat frequency response. Voicings set via
the PRE-SHAPE can be further modified using the GRAPHIC.
Balances the pre amplifier output level when the GRAPHIC is assigned. Raising the slider increases the
output level of the GRAPHIC. Lowering the slider cuts the output of the GRAPHIC. BALANCE has no effect when
EQ is not selected
Enables the onboard GRAPHIC. The GRAPHIC can also be switched via a footswitch on all models. FS2
