EFFECTS BLEND CONTROL
This function "blends" the signal sent from your bass, etc., with that coming from your effects
unit. With the Effects Blend control fully counter-clockwise ("dry"), no signal from your effect will
be heard. As you turn this control clockwise, more of the effect can be heard in the overall sound.
When the control is set fully clockwise ("wet"), no true or unaffected signal is heard other than
what your effects unit provides.
The Effects Blend circuit is similar to that used on recording consoles with the effects loop on a
"side chain" to the normal circuit. Unless the control is set to the full wet position, you will always
get the full sound of your instrument and get the diversity an effects unit offers. This circuit is
also effective in reducing noise caused by effects units because it is located after the gain
stages. When not using an effect, the Effects Blend control should be set to the fully counter-
clockwise position.
STEREO MASTER VOLUME CONTROL
The Stereo Master Volume control adjusts the volume of the internal power amplifiers. It should
be used in conjunction with the Gain control to achieve maximum signal-to-noise ratio. The SM-
500's Stereo Master Volume control is a dual-concentric knob that offers individual volume control
over both the right side (outer knob) and left side (inner knob) when the SM-500 is being run in
the Stereo Mode. When the SM-500 is being run in the Bridge/Mono Mode, the inner knob con-
trols the overall volume (the outer knob is disabled and will have no effect in Bridge/Mono Mode).
SPEAKER ON/OFF SWITCH
Moving the Speaker On/Off Switch to the "On" position allows the signal from the amplifier to be
heard through any speaker enclosure(s) connected to the SM-500's output section. Moving the
Speaker On/Off Switch to the "Off" position disables the SM-500's output section. This feature
allows the user to:
1. Use the XLR Output without using the internal speakers. This is especially useful in
recording when you are miking the speakers and only a direct signal is required.
2. Tune up without interfering with other band members while using the Tuner Output fea-
ture.
Note: If you do not hear any sound when you plug in and your system is properly connected, check the position of
the Speaker On/Off switch.
POWER ON/OFF SWITCH
Moving the Power switch to the "On" position will turn on you amplifier as indicated by the Power
LED lighting.

AC CORD RECEPTACLE
The SM-500 accepts a standard AC power cable (supplied with the SM-500), used with almost all
current musical, professional and household electronic devices. If it becomes misplaced, a
replacement can be purchased at almost any computer, electronics, or pro audio store.
Note: The rating for this cable is 3 conductor, 10 amperes minimum. If replacement is necessary, or if you need a
longer cable, look for the rating on the cable and be sure it is at least 10 amps.
