Compressor Active Indicators
– Light to indicate that the signal has
crossed the threshold of the compression circuit and that compression is
taking place.
Enhance Controls
– Called the “Magic Knob” by some, this complex
control simultaneously boosts the very low bass, upper middle, and high
frequencies while putting a dip in the lower middle frequencies. It is flat
when set to its minimum level (fully counterclockwise).
Tone Control Sections -
These controls allow you to boost or cut the tone at
the desired frequency. All controls provide 15dB of boost or cut and are
FLAT in the 12:00 position. The spacing allows the controls to interact
smoothly and musically. From left to right, the controls are:
Channel One:
Bass
– Centered at approx. 30Hz.
Low Midrange Control
– Centered at 550Hz. portion of the sound
envelope and can be critical to getting your sound right. The body of the
Bass Guitar sound is in the Midrange.
High Midrange Control
– Centered at 2.2KHz. Another useful control for
tailoring the Midrange, which is where the body of the Bass Guitar sound is
found.
Treble
– Centered at 11KHz.
Channel Two:
This channel is slightly different, in that it features sweepable Midrange. The
Level knob sets the amount of boost or cut; the Frequency knob adjusts the
center frequency from 250Hz to 2.5KHz. We’ll talk more about this later.
Dynamic Boost
– Immediately to the right of the Treble controls for each
channel you will find two switches labeled Bass and Treble. These engage
the Dynamic Boost. This feature allows the extreme lows and highs to be
adjusted to the ear’s relative loudness curve (Fletcher-Munson curve). This
ensures the bass will sound full and solid even at very low playing levels.
