MICRO SYNTH
Analog Guitar Synthesizer
Congratulations on your purchase of the Electro-Harmonix XO Micro Synth for guitar. This is a
very powerful tool for musical expression. Please take a few minutes to familiarize yourself with
the Micro Synth’s controls to learn how to get the best out of this special instrument.
The Micro Synth can create some of the most popular synthesizer textures at a fraction of the
cost for such capabilities. Its four voices: GUITAR, OCTAVE, SUB OCTAVE AND SQUARE
WAVE are completely independent and fully mixable. The MICRO SYNTH can modify these
signals with envelope control for a variety of “bowed” or “blown” sounds. In addition, a
sophisticated swept filter control allows highly variable frequency adjustments to be applied to
the overall output signal. When combined, these controls offer the user a creative capability that
is virtually limitless.
PREAMP GAIN ADJUSTMENT: The preamp gain in the Micro Synth has been set at the
factory for use with a guitar equipped with single-coil pickups. If you will be using another
instrument with higher or lower output, it may be necessary to readjust this setting. A
screwdriver or alignment tool with a tip width of no more than 1/16" is required. To access the
preamp gain adjustment, remove the bottom plate from the Micro Synth. Look for the small trim
pot in the lower left corner of the circuit board, it is labeled TRIM1 GAIN TRIM. Turning the trim
pot clockwise will increase the preamp gain. Turning it counter-clockwise will decrease preamp
gain. Please do not touch any other components when the bottom plate is removed or you risk
damaging the circuit board or the components.
OPERATION: The Micro Synth’s controls operate as described below. In all cases, high-
numbered control settings increase the level of the given effect.
FOOTSWITCH and Status LED – The Footswitch selects either effect mode or True Bypass.
When the Status LED is lit, the Micro Synthesizer is in effect mode. When the Status LED is off,
the Micro Synth is in True Bypass mode.
TRIGGER – Determines the input volume at which the filter circuits will “turn on.” It does not
affect any other circuitry. If the TRIGGER is set too high, the filter may “stutter” due to multiple
triggering. This is especially true if full chords are played. It is best to set the TRIGGER at
exactly the sensitivity needed for your playing.
WARNING:
Your
Micro Synth
comes equipped with
an Electro-Harmonix
9.6DC-200BI power
supply
(same as used by Boss™ & Ibanez™ 9.6 Volts DC 200mA). The Micro Synth requires 55mA at
9VDC with a center negative plug.
The Micro Synth does not take batteries. Using the wrong
adapter may damage your unit and void the warranty.
