Rear Panel
1. Amp Loop Ground Lift
This Ground Lift switch can be enabled to help prevent unwanted hum or buzz caused by ground
loops between the RP1000 and external amplifiers/preamps.
2. Input
High impedance 1/4” instrument input.
3. Amp Loop
These 1/4” send and return jacks let you connect to an external preamp or amplifier and use
the tone from these components instead of the internal amplifiers of the RP1000. A Ground Lift
switch is provided and can be enabled to help prevent unwanted hum or buzz caused by ground
loops between the RP1000 and external amplfiers/preamps.
4. Stomp Loop
These 1/4” send and return jacks let you connect to an external stompbox effect pedal into one
of 2 different positions of the RP1000 effects path.
5. Ground Lift Switch
This switch lifts pin 1 from the XLR Mixer Outputs from all ground references. This may be nec-
essary to help solve troublesome ground loops that can cause hum in the system, especially when
both XLR and 1/4” outputs are used together.
6. Amp/Mixer Switch
This switch optimizes the 1/4” Line Outputs for connecting to either a guitar amp system or
directly into the inputs of a mixer.
7. 1/4” Line Outputs
These 1/4” outputs can be plugged into a guitar amplifier or into inputs of a mixer or recording
device. The front panel Output Level controls the level of these outputs.
8. XLR Mixer Outputs
The XLR outputs are designed for connecting to a recording device or mixing console. These
outputs always have speaker compensation active as they are intended to be sent into full a range
audio system.
9. Headphone Output
Connect headphones here. Output optimized for use with headphones having 60 Ohms of
impedance or less.
10. Looper Control Input
This 1/4” TRS jack allow the optional FS3X footswitch to be connected for remote control of the
RP1000’s Looper feature.
11. USB Jack
The USB jack connects the RP1000 to a computer and provides two purposes. First it is used to
provide communication between the RP1000 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 RP1000 to record via the included Cubase ® LE4 recording software or any DAW recording
application.
12. Power Jack
Connect the included power adapter here.
13. Power Switch
Used to turn the RP1000’s power on and off.
