Chapter Five: Power Amplifier
5.1 Tone and Volume of the Power Amplifier
5.1.1 Master Volume
As the name suggests, this controls the overall, global volume of the
amplifier. For your enjoyment, there is also a second programmable
master volume control, which allows volume adjustments via remote
control while you are playing. Both controls are laid out so that even a
low-performance effects unit can be used and amplified in the loops.
5.1.2 Presence
This knob controls frequencies over 3KHz. Treble is produced and
dispersed in a very small beam from the speaker, so be sure to position
yourself in the projection area of the speaker when making
adjustments.
5.1.3 Deep
The Deep control is an active bass control, contrary to conventional
bass controls. It controls the frequencies around 120Hz without
influencing the overall dynamic range of the power amplifier. Diezel Co.
is not responsible for disintegrating speaker cabinets.
