Helix Phaser

Power / Switching the 

effect on and off

Power input

To power up your pedal, connect a power supply 
to its power input socket.

The power input socket of your TC Electronic 
effect pedal is a standard 5.5 / 2.1 mm DC plug 
(centre = negative).

Your TC Electronic effect pedal requires a 9  V 
power supply providing 100  mA or more (not 
supplied). TC Electronic recommends using the 
PowerPlug 9.

To minimize hum, use a power supply with iso-
lated outputs.

reo inputs (e.g. another stereo effect pedal), 
connect the MONO OUT jack of your TC Elec-
tronic effect pedal to the left input and the 
STEREO OUT jack to the right input of the 
other device.
