connect the ground (button out).
MIDI
M IDI I N
This jack receives MIDI signals, including Program Change commands and MIDI data dumps.
NOTE: Pins 1 and 3 of the MIDI connector are set up to output 10V DC phantom power to
our MIDI Mouse™ footcontroller (see Options on page 28).
M IDI T HRU /O UT
This jack normally functions as a MIDI Thru, which lets MIDI data entering the SansAmp
PSA pass through to other MIDI-controlled gear. This is useful when you employ a MIDI
footcontroller to control the SansAmp PSA and an effects processor. You can disengage the
MIDI Thru by using Special Page Function 9 (see page 21).
When you off-load custom preset data or MIDI map data , this jack operates as a MIDI Out.
(See Special Page Function 1, page 17.)
Always use good-quality MIDI cables for connecting the SansAmp PSA with other gear.
HEADPHONE
Dedicated stereo 1/4-inch output. Be aware that you will hear in stereo only if you use a stereo
effect in the Effects Loop.
CAUTION: Do not use a mono 1/4-inch cable in this output.
SUGGESTED SETUPS
The following three pages show you how to interface your SansAmp PSA with other gear,
including MIDI equipment.

The front-panel Input jack is designed to accept signals from guitars, basses, keyboards, etc.
You can set up your SansAmp PSA as a permanent part of a rack or patch-bay setup, with its
usual input source plugged into the rear-panel jack. Then, if you want to plug straight into
the SansAmp PSA, use the front-panel Input, which overrides the rear-panel Input 2.
