Pigtronix Envelope Phaser II - Manual (Page 4)

Anatomy of the EP2:
The Interface:
Jacks:
1. DC POWER 18-VOLTS – Use only the 18-Volt, 300mA, negative tip
power supply that came with your Pigtronix EP2. Using the wrong
power supply is likely to result in a damaged pedal.
2. IN – Effect input, Plug in your instrument here.
3. OUT – Effect output, Plug in your amp, mixer, or DI box here.
4. EF TRIGGER – This audio input connects directly to the envelope
follower. Any signal plugged into this jack will override the input signal
as the source for the envelope modulation.
5. SWEEP PEDAL - This is the TRS expression pedal input for using the
Envelope side of the pedal as a foot controlled phase-wah. When an
expression pedal is plugged into this jack, the envelope follower
circuit is bypassed.
