CONTROL VOLTAGE or EXPRESSION SECTION:
Using the EXP knob and an external EXPression pedal or control voltage
with your ACV-1 will greatly increase the dynamic playing and tonal
possibilities as well as expand the control range beyond the extent of the
front panel knobs alone. Use a standard 10-50K linear expression pedal
that uses the +5V voltage supplied on the ring jack and outputs the control
voltage on the tip or use a 0-5V external CV voltage from a Eurorack
module, Synthesizer, DAW, or similar source.
CAUTION:
Voltages over +5V or below 0V may damage your ACV-1.
Use only standard 0-5V control voltages. If your expression pedal has a
trim knob, you may find it helpful to use this feature to reduce the range of
the expression pedal to less than a full knob sweep to make it easier to dial
in the exact sound you seek.
Please note: In order to give a wider playing capability with expression
inputs, the control setting selected by the EXPression switch will reduce
the knob range and setting slightly. Think of it as turning the knob to -1.
The EXP controls are additive with their corresponding knob in that the
EXP input is added to the knob. For full control voltage range set the knob
to the most counterclockwise (CCW) setting, however using both you may
get delay times, feedback amounts, LFO rate or amount beyond those that
can be achieved using just the knob. Unlike the ADG-1, the ACV-1 time is
additive like the rest of the controls. Delay times beyond the normal TIME
knob position will produce an aliased or ring modulated sound.
Use only your fingers, a plastic screwdriver, guitar pick or similar plastic
device to turn the 4-position EXP rotary switch. Never use a metal object
that could damage the shaft. If you use this feature frequently, we have
included a knob (C&K part # 297F02000). Note this knob will turn the
shaft but there is not enough shaft length through the enclosure to
permanently secure the knob to the shaft and it may fall off. Do not glue
the knob to the shaft or your ACV-1 will not be serviceable.
