X AIR User Manual
The PREAMP knob adjusts the amount of input gain prior to the band-specific
distortion adjustment. BUZZ adjusts the low-end breakup, PUNCH adjusts
the midrange distortion, and CRUNCH tailors the high-frequency content and
distortion for smooth or cutting notes. The DRIVE knob simulates the amount
of power amp distortion from a tube amp. The LOW and HIGH knobs allow
EQ adjustment independent of distortion content, and the overall output is
controlled by the LEVEL knob. The CABINET simulation can be bypassed if the
guitarist is already using a real cab, which allows the effect to function like a
boost or distortion pedal. The Dual Guitar Amp allows the left and right channels
to be adjusted independently.
Tube Stage
Tube Stage/Overdrive is a versatile effect capable of emulating a variety of
modern and classic tube preamps. Available in stereo and dual-mono versions,
use Tube Stage/Overdrive to dial in warm and fuzzy sounds from subtle to
fully saturated.
DRIVE adjusts the amount of harmonics being driven by the effect. EVEN and ODD
adjust the amount of even and odd harmonics. GAIN adjusts the output gain of
the effect. LO CUT sets the input frequency below which the source signal will not
pass through the effect. HI CUT sets the input frequency above which the input
signal will not pass through the effect. BASS GAIN/FREQ adjust a low shelving
filter at the output of the effect. TREBLE GAIN/FREQ adjust a high shelving filter at
the output of the effect.
Stereo / Dual Pitch
Pitch shifting is often used in two different ways. One is to set the Mix knob lower
and only use the Cent knob to make a small off set in pitch between the wet and
dry tones. This results in a "voice doubling" effect that thickens the overall sound
in a more subtle way. The extreme use of the effect is to turn the Mix knob fully
clockwise so the entire signal is effected. This way, the signal can be shifted into
other keys up to an octave above or below the original. When used on a voice,
this results in a "chipmunk" sound or a low Darth Vader effect.
When the SEMI and CENT knobs are set at 12:00, the pitch is not altered.
Making adjustments by semitone will have a very pronounced effect,
whereas changes to the CENT knob will be very minor. The DELAY knob creates
a time difference between the wet and dry sound. The LO and HI CUT knobs
allow the effected signal to be band-limited. The Dual Pitch effect allows
the left and right channels to be adjusted independently, and allows GAIN
compensation and panning of the two channels.
