E. AURAL ENHANCER—Featured on just about every SWR
amplifier since the company's inception in 1984, the Aural
Enhancer delivers that famous SWR Sound! It brings out
the fundamental low notes of the bass guitar, enhances
the high-end transients, and reduces specific frequen-
cies that mask the fundamentals. This provides a more
transparent sound, particularly when slapping and pop-
ping and also gives "active" bass characteristics to pas-
sive basses (when set at "2 o'clock" or positions further
clockwise).
How the AURAL ENHANCER Works: Think of it as a vari-
able tone curve that changes depending on where you
set the AURAL ENHANCER control knob. As you rotate
the control clockwise from the "MIN" position, you are
elevating low– mid– and high–frequencies different than
those of the active tone controls. This remains true up to
about the "2 o'clock" position, a favorite of many players
because it brings out the low-end fundamentals and crisp
highs plus lower midrange to help cut through the band.
However, if you go further clockwise past the "2 o'clock"
position, the mids centered around 200 Hz will start to
drop off. From this point on, the effect becomes much
more pronounced. However, the curves involved here are
gentle, as opposed to the extreme curves you can create
by boosting or cutting the active tone controls.
Most significantly for basses, the AURAL ENHANCER™ will
help bring out the fundamentals of your lower registers
without masking them with overtones, as is possible
when using the BASS control only. At the same time, it
opens up the sibilance characteristics of all instruments
without being harsh.
F. ACTIVE TONE CONTROLS—Shelving type, 3–band equal-
ization:
• BASS—Adjusts low-frequency response ±15dB in the
30Hz–150Hz range.
• MID—Adjusts mid-frequency response ±15dB in the
500Hz to 1kHz range.
• TREBLE—Adjusts high-frequency response ±15dB in the
2kHz to 14kHz range.
G. EFX BLEND—Functional only when a plug is inserted
into the EFFECTS RETURN {Q} jack, this knob sets your
effects level by controlling the amount of "wet" effects
loop signal blended into the "dry" preamp signal.

H. BASS INTENSIFIER™—Exclusive SWR® tone circuit that
integrates low-frequency boost with a smooth, fast-acting
compressor. This provides a radical increase of specific
bass and low-midrange frequencies without the usual
side-effect of overdriving the amplifier circuitry. This lit-
erally intensifies the bass tone in your sound! Use it for
the heavier sections of a song, or as part of your overall
preferred sound.
To best hear what the BASS INTENSIFIER does: 1. Decrease
MASTER Volume to half its normal setting (or less). 2. Set
CUTOFF to 80Hz. 3. Play a note repeatedly and slowly
rotate CUTOFF clockwise. You will hear frequencies being
boosted as you turn the dial and the overall effect will
seem louder as more frequencies are boosted. Your ears
are the best judge, so take some time to experiment and
hear what works best.
I. WEDGE EQ—Use this tone circuit preset when playing
the amplifier with the cabinet in the tilt-back position.
The Wedge EQ compensates for the acoustics lost with
cabinet floor contact and the redirected tweeter horn.
J. LIMITER—This circuit protects the power amp and speak-
ers from damage by governing peak signal strength,
allowing you to play at maximum loudness levels safely.
DEFEAT turns the Limiter OFF.
K. MASTER VOLUME—Use to adjust the loudness of the
WorkingPro after all other levels are set, including any
external effects. MASTER Volume affects the BALANCED
OUTPUT {U} and the UNBALANCED LINE OUT {S} levels
when DIRECT/LINE {U} is set to
when you do not want MASTER to change the signal level
output to sound equipment.
L. POWER SWITCH—Switches the unit ON-OFF as indicated
by the LED.
◊
ENGAGE—Activates the BASS INTENSIFIER circuit as
indicated by the LED .
CUTOFF—Adjusts the frequency range boosted by
the BASS INTENSIFIER. When fully counter-clockwise,
only frequencies below ~80Hz are affected. When fully
clockwise, frequencies below ~200Hz are affected.
DEFEATED (LIMITER OFF)
ACTIVE—Indicates exactly when the LIMITER circuit is
working (when LIMITER is ON).
POWER AMP CLIP—Alerts when the power amp signal
is being overdriven and distorting. Power amp clipping
can be harmful to equipment! Use the LIMITER or reduce
MASTER Volume {K} if POWER AMP CLIP flashes often.
