AURAL ENHANCER
The Aural Enhancer is a feature that's been on just about every SWR amplifier since the company's inception in 1984, and is a trade-
mark part of the "SWR Sound" people have come to know and love. It was developed to help bring out the fundamental low notes of
the bass guitar, enhance the high-end transients, and reduce certain frequencies that help "mask" the fundamentals. The ultimate
result is:
1. A more transparent sound, especially noticeable when slapping and popping.
2. It can make a passive bass take on an "active" type of quality when set at positions of "2 o'clock" or further clockwise.
Let's take a second to learn how the Aural Enhancer works. Think of it as a variable tone curve that changes depending on where you
set the Aural Enhancer control knob. As you raise the control clockwise from the "MIN" position, you are elevating a whole range of
sound (lows, mids, and highs) at a variety of frequency points selected specifically because they're different than those selected for
the individual Tone Controls.
This remains true up to about the "2 o'clock" position. This position—a favorite for many users—brings out both the low end fundamen-
tals and crisp highs and, at the same time, adds a little lower midrange to help cut through the band. However, if you go further clock-
wise and past the 2:00 position, selected mids will start to drop off—specifically, a group of frequencies centered around 200 Hz. At this
point and after, the effect becomes much more pronounced. However, the curves involved here are gentle, as opposed to the very
extreme curves you can create by boosting or cutting the Active Tone Controls (EQ).
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.
Obviously, numbers and curves and circuits all mean nothing compared to what you hear with your own ears. Play a chord, a repeated
lick, or a harmonic, and turn the Aural Enhancer control to various points on the knob to hear the effect for yourself. As always, your
ears are the best judge when it comes to settings that affect the tone of your instrument.
SubWave™ CONTROLS
Based on the circuit from SWR's groundbreaking Mo' Bass Soundstation, the SubWave™ on your Black Beauty is a lightning-quick
sub-octave wave engine with tracking superior to other models of sub-octave effects currently on the market. In plain terms, it hears
the note you play and immediately generates a signal one octave below it—all the way down to low "C#," "C," or even low "B" on some
basses!
SubWave™ ACTIVATOR SWITCH
Located directly above the SubWave™ Level Control, this is an illuminated push-button switch that activates the SubWave™
effect. When engaged, the switch cap will illuminate in blue. Push once to engage, then again to disengage. (The SubWave™
effect can also be switched on and off via footswitch; please see "SubWave™ Footswitch" in the "Rear Panel Features" section
later in this guide.)
SubWave™ LEVEL CONTROL
Once the SubWave™ effect is engaged, you can use this control to determine the amount of effect to be blended in with your
original ("clean") bass signal. Turning the control clockwise will increase the amount of effect, while turning the control counter-
clockwise will decrease the amount of effect. When the control is set fully counter-clockwise to "MIN," no effect will be heard,
even though the effect is engaged and the Activator switch is illuminated in blue. This is normal. Also, when the control is set
fully clockwise to "MAX," the "clean" bass signal will still be present...along with plenty of sub-octave effect. As always, your ears
and the desired musical application will be the best judge in setting this control.
(Keep in mind that the Bass Level control will have a significant impact on the perceived level of the SubWave™ effect as well,
as it follows immediately after the SubWave™ in the signal chain. Please read below.)
