D. AURAL ENHANCER A trademark SWR® feature for over
years, 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 that opens up the sibilant characteristics of all
instruments without being harsh.
How the Aural Enhancer works: Think of it as a variable
tone control that changes frequency range AND level
according to where you set the Aural Enhancer control:
As you rotate the control clockwise from the "MIN"
position, you are elevating low-, mid-, and high-frequency
levels in ranges that are different, yet complementary
to the Bass and Treble tone controls. The " 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, selected mids will drop off—specifically, a
group of frequencies centered around
apparent, the Aural Enhancer is gentle compared to the
extreme response curves you can create with the EQ
tone controls.
E. SUBWAVE SWITCH Activates the Subwave circuit, as
indicated by the blue
F. SUBWAVE An octave divider circuit that intensifies
bass frequencies by generating tones an octave below
the input signal. Adjust the amount of Subwave signal
mixed in with the "dry" signal.
G. BASS Adjusts low-frequency signal response ± dB
centered around Hz.
H. MID RANGE Semi-parametric tone controls that
allow you to boost or cut signal response
at a chosen mid-frequency range. With the
Frequency knob, select a range from
to Hz, then use the Level knob to adjust
response ± dB in that range. Mid–range
tone is critical for most instruments and the optimal
settings will depend on the situation—what may sound
harsh while playing in a garage may sound just right in
a crowded room or on a recording.
I. TREBLE Adjusts high-frequency response ± dB above
the kHz range. Because high frequencies are inherently
directional (narrowly focused), it is important to listen
from different angles to find the best treble setting and
the optimum placement for your amplifier.

compression circuit.
K. MASTER VOLUME Use to set the loudness output
from your speakers after all other levels are set, including
any external effects.

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 or increase the Compression {J} level
if this LED is ON (unlike preamp clipping, power amp
clipping can be harmful to the amplifier).
L. LINE OUT CONTROL Command center for the rear
panel Balanced Output {V} jacks.
•
LINE / DIRECT / DIRECT SUBWAVE—Selects the
source point in the signal path for the Balanced Output
{V} jacks. LINE includes all tone, compression and effects
circuits. DIRECT is a true all-tube signal path taken
immediately after the first tube preamp stage. DIRECT
SUBWAVE is the Direct signal, plus the Subwave circuit.
• MUTE / LIVE—Select MUTE to disable the Balanced
Output {V} jacks if you want to play through just the
Speakers {Q/R}.
• GROUND / LIFT—Select LIFT to disconnect the
ground connection (pin- ) from the XLR jack to reduce
noise caused by ground loops. Normally leave this switch
in the GROUND position.
• PAD— Adjusts the output level of the Balanced
Output {V} jacks to accommodate the input sensitivity of
connected sound equipment.

inserted into the FX Loop Return {U} jack, this knob sets
your effects level by controlling the ratio of "wet" effects
