4. Headphones
Connect a pair of stereo headphones to this 1/8" jack. For proper frequency response, the Amp/
Mixer switch should be set to Mixer ("in" position) when using headphones. Headphones with an
impedence of 100 Ohms or less are recommended.
Note: The Headphones output can have either a mono or stereo signal, depending on what 1/4"
outputs are connected. If neither (or both) 1/4" outputs are connected, the Headphones output
will be in stereo. If a cable is connected to the Left (Mono) 1/4" output only, the Headphones
output will be in mono.
5. Control In
You can connect a passive volume or continuous control pedal to this 1/4" jack to control the a
Wah and/or the Whammy when either or both of those effects are turned on. When neither
TM
Wah nor Whammy is turned on, the pedal controls the RP155's volume by default.
6. USB Jack
The USB jack connects the RP155 to a computer and provides two purposes. First it is used to
provide communication between the RP155 and the X-Edit™ Editor/Librarian software. Second, it
is used to stream four channels of audio (2 up / 2 back) to and from the computer when using the
RP155 to record via any DAW recording application. Knobs 2 and 3 also control the direct/play-
back mix and USB record level when USB is connected and the Pickup Row is selected.
Note: You can download the X-Edit Editor/Librarian software and USB drivers at www.digitech.com.
7. Power Input
Connect only the DigiTech PS0913B power supply to this jack.
