General Characteristics
... STUTTERFLY SY-1 is intended for use both in studio and live performances.
AMT STUTTERFLY SY is a digital delay line.
The unit is based upon the high-quality DSP providing wide dynamic range of the
device. The original circuitry design developed by ... experts resulted in
insignificant current consumption (less than 36m.). The refusal from operational
amplifiers traditionally used in similar devices in favor of JFET has dramatically
enhanced the pedal's sound.
The device features passive bypass which on one hand requires high-quality cables
but on the other hand retains the original instrument sound when the effect is off.
AMT STUTTERFLY SY-1 Features
• passive bypass;
• direct signal untouched by the processor, totally analog;
• JFET transistors in sound section;
• high-quality components,
• film capacitors in sound section;
• lightness and compactness;
• low voltage consumption.
WARNING!
AMT STUTTERFLY SY-1 like any other high-class device is sensitive
to the power adaptor quality. We do recommend to use either 9V
6F22 battery or high quality power adaptor matching the device's
specifications.
Before you start
For the purpose of transportation the device was carefully packed by the
manufacturer. However, if cardboard packaging is damaged, it is necessary to check
the device for the presence of external damages.
.. In case of damages do not send the device to us, but inform the
seller and transport agency since otherwise you lose the right

.. In order to avoid damages during storage and transportation
always use original packaging.
.. Do not allow children to play with the device and packaging
materials.
.. Please recycle all packaging materials in the way harmless to
environment.
.. Operating the device next to powerful radio transmitters and
sources of high-frequency signals can lead to significant sound
distortion. In this case increase the distance between the
device and the transmitter and use the screened cables for all
interconnections.
