OPERATION MANUAL

<<< Power Requirements >>>

<<< Tech Specs >>>

• Current Draw: 86mA

• This device take a standard 9 volt DC power supply with a 2.1mm negative center barrel. We

always recommend pedal-specic, transformer-isolated wall-wart power supplies or multiple

isolated-output supplies. Pedals will make extra noise if there is ripple or unclean power.

Switching-type power supplies, daisy chains and non-pedal specic power supplies do not lter

dirty power as well and let through unwanted noise. DO NOT RUN AT HIGHER VOLTAGES!

• Input Impedance: 10M Ohm • Output Impedance: 1K Ohm
