Q-TRON
Envelope Controlled Filter
-OPERATING INSTRUCTIONS-
Congratulations on your purchase of the Q-Tron envelope controlled filter! You have
purchased a very powerful tool for musical expression.
Please take a few minutes to familiarize yourself with the Q-Tron's controls and how they
work.
Envelope controlled filters are a unique type of sound modifier where the intensity of the
effect is controlled by the user's playing dynamics.
The volume (also know as the envelope) of an incoming audio signal is used to control a
swept filter. As the volume increases or decreases so does the pitch of the filter.
-CONTROLS-
Drive Switch (Up/Down) – Selects direction of filter sweep
Range Switch (HI/Lo) – Emphasizes vowel-like sound in low position and overtones in high
position.
Gain Control (0-11) – Functions as both a volume control and a filter sensitivity control in
boost mode. In Normal mode the Gain control acts as a filter sensitivity control and has no
effect on the unit's output volume.
Boost Switch (Normal/Boost) – Normal mode disengages internal pre-amp, Boost mode
activates it. Also determines function of Gain control (see above).
Peak Control (0-11) – Determines frequency peak of filter. This control will create a more
dramatic effect when turned clockwise.
Mode Switch (LP, BP, HP, MIX) – Determines what frequency range the filter will sweep in.
Emphasizes lows in Low Pass, midrange in Band Pass, treble in High Pass. Mix mode
combines BP with dry instrument signal.
Bypass Switch (in/out) – Disengages effect.
Lastly, the Q-Tron's effect can be controlled by the user's playing dynamics. A strong attack
will yield a more dramatic effect, while softer playing will yield more subtle effects or none at
all.
