H. AURAL ENHANCER—Push this knob to switch the Aural
Enhancer between ON and OFF. The Shift {G} LED will turn
off to indicate when the Aural Enhancer is OFF (defeated).
NOTE: For a true "flat" frequency response, defeat the Aural
Enhancer and set all three EQ {I} Level knobs to their center
detent positions.
The Aural Enhancer brings out the fundamental low notes
of the bass, brightens high-end transients and reduces
certain frequencies that "mask" the fundamentals. The
ultimate effect is a more transparent sound without being
harsh.
How the Aural Enhancer works: Think of it as a variable tone
control that adjusts frequency range and level according to
the knob's position:
As you rotate the knob from the "DRY" position, you are
elevating low-, mid-, and high-frequency levels that are
subtle compared to the EQ tone controls. The "2 o'clock"
position—a favorite for many players—brings out both low
end fundamentals and crisp highs, while at the same time
adds a little lower midrange helping you to cut through
the band. Then, as you rotate further clockwise, specific
mids will drop off—specifically, the group of frequencies
selected by the Shift {G} button.
I. EQ—These three semi-parametric tone controls
allow you to boost or cut signal response at
the frequencies you choose. With the outer
Frequency knobs, select the frequency ranges
M. POWER SWITCH—Switches the unit ON-OFF.
N. IEC POWER CORD SOCKET—Connect the included power
cord to a grounded A/C electrical outlet in accordance with
the voltage and frequency ratings specified on the top
panel of your amplifier.
O. SPEAKER OUT—Connect a speaker cabinet here using
the Speakon® connector. The speaker load must be 4Ω
minimum and capable of handling 400 watts (300 watts for
100V Japanese models). Read Speaker Guidelines on page 9
before making speaker connections.

range tone is crucial for most instruments and the optimal
settings will depend on where you are—what sounds harsh
while playing in a garage may have just the right edge in a
crowded room.
J. EFFECTS BLEND & COMPRESSION—The outer knob
controls your Effects level by setting the ratio of "WET"
effects signal to be blended into the "DRY" preamp signal.
The inner knob adjusts the ratio of signal Compression,
useful for preventing signal spikes and increasing sustain.
K. POWER AMP CLIP LED—Indicates when the power amp is
being overdriven (clipping) and warns you of the potential
for overheating and damage. Reduce the Master Volume {L}
or increase the Compression {J} level if this LED illuminates
(unlike preamp clipping, power amp clipping can be harmful
to the amplifier).
WARNING: Due to the compact design of your headlite
amplifier it is very sensitive to heat and adequate ventilation
must be maintained. If the amplifier overheats it will shut
down until it cools off, generally for a very short period of
time.
L. MASTER VOLUME—Controls the overall loudness of the
headlite amplifier.
