C. LIMITER - Adjusts the signal level threshold at
which the Limiter circuit becomes active. Rotate
clockwise to lower the Limiter threshold or fully
counter-clockwise to remove the Limiter from the
signal path completely.
The Limiter circuit prevents the signal level from
exceeding very far above the set threshold. This
moderating effect allows you to continuously
operate closer to maximum volume levels
without fear of overdriving the power amplifier or
speakers. NOTE: Loss of volume caused by
extreme Limiting can be overcome by increasing
the Master Volume {I}.
ACTIVE LED- Indicates exactly when the
Limiter circuit is working. If the Limiter does not
activate (even at max) increase Gain {B}.
D. AURAL ENHANCER - A trademark SWR ® feature
for 20 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 sibilance 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 “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, selected mids will drop off—
specifically, a group of frequencies centered
around 200Hz. While apparent, the Aural
Enhancer is gentle compared to the extreme
effects you can create with the basic tone
controls.
Your ears are the best judge when it comes to
controls that affect the tone of your instrument.
Play a note, a repeated lick, or a harmonic, and
turn the Aural Enhancer to various settings and
hear the effect for yourself!
E. BASS - Adjusts low-frequency signal response
±15dB centered around 80Hz.
F/G. 4-BAND VARIABLE GRAPHIC EQ - Each
level slider {F} adjusts signal response
±15dB at the frequency set by the
frequency knob {G} directly below. To
find and adjust a particular frequency
in a band, set the level slider to +15,
then rotate the frequency knob below to the
desired frequency. Finally, adjust the level slider
as desired.
NOTE: When a slider is in the “0” position, that
band has no effect on your signal regardless of
the position of the Frequency knob below.
TIPS: If you need to “cut through” the band, try
boosting the 200–400Hz range. If you like a more
transparent or “scooped” sound, try cutting in
the 800Hz range.
H. TREBLE - Adjusts high-frequency signal
response ±15dB centered around 2kHz.
I. TRANSPARENCY- Adjusts ultra-high frequency
signal response ±15dB centered around 5kHz.
J. EFFECTS BLEND - Controls how apparent your
effects sound, or more precisely, the mix ratio of
direct signal
(dry) to effects loop signal (wet).
Effects Blend is only enabled when a plug is
inserted into any of the Effects Loop {U} return
jacks.
K/L. STEREO MASTER VOLUME - Adjusts the
volume output to your speakers: When operating
in Stereo Mode, use the inner {K} and outer {L}
knobs to adjust left and right channel volumes
respectively. When operating in Bridge Mode,
use only the inner {K} knob to adjust the loudness
of the SM-500 power amps.
M. SPEAKER - Disconnects the speaker outputs,
useful for silent tune-ups and instrument
changes.
N. POWER - Switches the SM-500 on-off as
indicated by the LED.
