BASS MICRO SYNTH
Analog Bass Synthesizer Congratulations on your purchase of the Electro- Harmonix XO Bass Micro Synth! You have purchased a very powerful tool for musical expression. Please take a few minutes to familiarize yourself with the Bass Micro Synth’s controls and how they work The XO BASS MICRO SYNTH can create many of the most popular analog lead synthesizer textures at a fraction of the normal cost for such capabilities. Its four voices: GUITAR, OCTAVE, SUB-OCTAVE, and SQUARE WAVE are completely independent and fully mixable. The BASS MICRO SYNTH can modify these signals with envelope control for a variety of “bowed” and “blown” sounds. In addition, a sophisticated swept filter control allows highly variable frequency adjustments to be made to the signal. When combined, these controls offer the user a creative capability that is virtually limitless.
WARNING: Your Bass Micro Synth comes equipped with an Electro-Harmonix 9 .6DC-200BI power supply (same as used by Boss™ & Ibanez™ 9.6 Volts DC 200mA). Use only the adaptor supplied. Using the wrong adapter can cause serious bodily injury. Using the wrong adapter may also damage your unit and will void the warranty. In addition, do not use a daisy chained supply with the Micro Synth. The Micro Synth must have its own power supply.
PREAMP GAIN ADJUSTMENT
The preamp gain in the Bass Micro Synth has been set at the factory for use
with a bass equipped with single-coil passive 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 Bass 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 Bass 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 Bass Micro Synthesizer is in
effect mode. When the Status LED is off, the Bass 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 chords are played. It is best to set the TRIGGER at exactly the
sensitivity needed for your playing. The next four controls of the BASS MICRO
SYNTH comprise the VOICE MIXING section: GUITAR, SUB-OCTAVE (one octave
below), OCTAVE (one octave above), and SQUARE WAVE. Each voice is completely
independent and can be mixed with the others in any degree. Please not the
following voice characteristics:
- GUITAR: Controls the output volume of the input signal through the filter.
- SUB OCTAVE: Controls the output volume of the Sub-Octave. The Sub-Octave effect only tracks single notes.
- OCTAVE: Controls the output volume of the Octave. The Octave only tracks single notes. This voice contains a small amount of harmonic distortion for added richness of tone.
- SQUARE WAVE: Controls the output volume of the Square wave. Intensity of this voice is also determined by instrument attack or volume. In all other respects it operates in a similar fashion to a standard distortion device.
ATTACK DELAY
Determines the time required for the voice signals to reach full volume. Higher-numbered settings can completely remove the initial attack of the instrument. Different delay times contribute greatly to the characteristic sounds of various instruments. It is recommended that you synchronize your playing to the speed setting of the ATTACK DELAY. The final four controls comprise the FILTER SWEEP section.
- RESONANCE: Affects the degree of sharpness, or “Q” of the filter. Higher settings will produce a more emphasized filter sound and also add a slight boost to the signal.
- START FREQUENCY: – Determines the frequency at which the filter sweep begins.
- STOP FREQUENCY: Determines the frequency at which the filter sweep ends. This is also the “resting frequency” of the filter, and if the START and STOP controls are set at the same level no sweep will occur, though the filter will provide emphasis of that particular frequency band. In addition to lead synthesizer sounds, START and STOP controls can be used to simulate attack, decay, and harmonic content of acoustic instruments.
- RATE: Determines the speed at which the filter sweeps from START FREQUENCY to STOP FREQUENCY. It is recommended that RATE be synchronized with your playing speed.
- SOUND TEMPLATES: The sample settings include with these instructions will help you get -familiar with your BASS MICRO SYNTH and its controls. Once you’ve tried all the sample settings, feel free to experiment to develop your own unique palette of sounds. You can record your new settings in the blank templates provided.
Power
IMPORTANT PLEASE READ: The Micro Synth will not work with the same power
adaptor that is daisy chained to other pedals in its signal chain. Please run
the Micro Synth off of its own power adapter.
9V Power Jack – Connect the plug from the supplied 9VDC AC Adapter to the 9V
power jack. Do not use a power supply that is daisy chained to other pedals in
the signal chain.
