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.
