Flat EQ is achieved with this control set fully clockwise.

Cut

The Cut control is a passive treble cut located in the power amp section. This

control can tame the upper registers beyond the frequency range emphasized by

the Treble control. This is especially useful if you're overdriving the

amplifier—allowing you to tame the harmonics added by distortion introduced in

earlier stages and in the power amplifier itself.

For a cranked tone, turn up the Treble control—which will push the tubes a little

harder—and also turn up the Cut control, in turn, to tame the resulting high end.

Flat EQ is achieved with this control set fully counterclockwise.

Additional Information on Flat EQ

Although, technically, flat EQ is achieved with the Treble and Bass controls at

around 11 o'clock, the Middle control fully clockwise, and the Cut control fully

counterclockwise, most guitar players are used to playing amplifiers with a

midscooped sound, so the D₂O may actually sound subjectively neutral with all

controls set at 12 o'clock.

It is difficult to make this amplifier sound bad! Experimentation with extreme and

bizarre EQ settings is highly encouraged. Don't be afraid to try setting knobs all

the way up or all the way down. Try a lot of different settings and see what works

for you.

Matching Speaker Load

A common point of confusion is how to set the output impedance of the amplifier

in order to match the attached speaker load. If only using a single speaker

cabinet, this is easy. Set the impedance selector switch to match the impedance

of your speaker cabinet and plug your speaker cabinet into the MAIN speaker

output.

The two speaker outputs on the D₂O are wired in parallel. When connecting two

speaker cabinets, using both the MAIN and AUX outputs, the rule is that both

speaker cabinets must be the same impedance and the total impedance seen by

the amplifier will be half the impedance of one speaker cabinet by itself. For

example, if you connect two 8Ω speakers, one to each output jack of the D₂O,

you should set the impedance selector switch to 4Ω.
