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.
