720
Stereo Looper
Congratulations on your purchase of the 720 looper! Enjoy 720 total seconds of high-quality, stereo recording time and the ability to store 10 different loops. The 720 looper is packed with features such as reverse and ½ speed effects, playback fadeout, real-time progress display, and a convenient programmable second footswitch.
WARNING: Your 720 comes equipped with an Electro-Harmonix 9.6DC-200 power supply (same as used by Boss® & Ibanez®: 9.6 Volts DC 200mA). The 720 requires 75mA at 9VDC with a center negative plug. Using the wrong adapter or a plug with the wrong polarity may damage your 720 and void the warranty.

– CONTROLS and INDICATORS –
LEVEL Knob – Controls the output level of the Loop being played. Your dry signal remains at unity signal level from input to output. The dry signal also remains analog throughout the 720.
LOOP Footswitch – Use the LOOP footswitch to record, overdub, and playback loops. The LOOP footswitch can also be used to stop and undo-redo loops. See the QUICK START GUIDE on page 5 to learn how to use this footswitch to create loops.
STOP/FX Footswitch – The STOP/FX footswitch can be set to either STOP mode or FX mode. Select either mode by pressing and holding the PUSH: MODE button for 2-seconds. When in STOP mode, a DOT appears on the display next to the STOP label. When in FX mode, the DOT is off.
REC LED – Indicates when a loop is being recorded or overdubbed.
PLAY LED – Indicates when a loop is being played or overdubbed.
MEM LED – Indicates loop audio is in memory for the current loop bank.
LOOP Knob and PUSH: MODE Button – The LOOP knob has no pointer because it is attached to a rotary encoder that can be continuously rotated in either direction. This knob also has a PUSH: MODE button with two functions: 1) to cycle through one of three available modes, and 2) once a mode is selected, to adjust the value of that mode from 0-9. All modes and values are shown on the digit display.
SELECTING/ ADJUSTING MODES – The 3 selectable modes are toggled on and off by pressing the MODE button once. When mode-select is active, the digit display will flash the currently selected mode. Turn the LOOP knob to cycle through the three possible modes:
L = Loop Select
p = Loop Progress
F = Fadeout Time
When you arrive at the mode you would like to adjust, press the MODE button once to select the mode. The display will stop flashing and it will show the selected mode value from 0-9. The selected mode can now be adjusted with the LOOP knob from 0-9.

REVERSE Button – Press the REVERSE button to play the loop in reverse. The REVERSE button glows red when enabled. Reverse can be used at any time to playback or overdub a loop.
½ SPEED Button – Pressing the ½ SPEED button causes the pitch of the loop to go down one octave and the tempo is halved. If a loop is overdubbed during half-speed mode, returning to normal speed playback causes the pitch of the overdub to go up one octave and the tempo is doubled. The ½ SPEED button glows red when enabled. ½ SPEED can be used at any time during playback or while overdubbing a loop.
FX LED – Indicates when an effect is active. The FX LED automatically lights when the REVERSE or ½ SPEED buttons are used and the STOP/FX footswitch is programmed to operate in STOP mode. Alternatively, the FX LED will toggle on/off each time the STOP/FX footswitch is pressed and programmed to operate in FX mode.
MONO/L INPUT – ¼” Left Instrument/Line Input Jack. Plug the output of your instrument or another effects pedal into this jack. If you use just one input we recommend you use the MONO/L input. The input impedance presented at this jack is 1MΩ. The maximum allowable signal level into this jack is +6 dBu. The input is unbalanced.
R INPUT – ¼” Right Input Jack. Plug the output of your instrument or another effects pedal into this jack. Use this jack for stereo recording. The input impedance presented at this jack is 1MΩ. The maximum allowable signal level into this jack is +6 dBu; it is an unbalanced input.
MONO/L OUTPUT – ¼” Left Output Jack. The Left output signal is sent through this jack. The dry signal present at the Left input will be output on the MONO/L Output jack. The source impedance of the MONO/L Output is approximately 330Ω.
Note: the MONO/L OUTPUT jack also functions as a power switch when powered from a battery. Disconnect the cable to save battery power when the 720 is not in use.
R Output – ¼” Right Output Jack. The Right output signal is sent through this jack. The dry signal present at the Right input jack is output to the R Output jack. The source impedance of the R Output is 330Ω.
FC Jack – ¼” TRS Foot Controller Jack. Use this jack with popular three button foot controller units to control the 720 bank up, bank down, and instant undoredo.
The Digitech® FS3X 3-Button Footswitch [see: http://digitech.com/en- US/products/fs3x-3-button-footswitch] is recommended for this application. If using this product, the following switch labels on the FS3X control the following 720 functions: DOWN advances the 720 bank down; UP advances the 720 bank up; and, MODE will instantly undo or redo.
The circuit required for the foot controller is as follows:
TIP / S1 = Instant Undo-Redo
RING / S2 = Bank Down
Diode-AND TIP+RING / S3 = Bank Up
9V Power Jack – Plug the output of the supplied AC adapter into the 9V power jack located at the top of the 720. The Stereo Looper 720 draws 60mA typ./75mA max. at 9VDC with a center-negative plug. The Stereo Looper 720 accepts Boss® and Ibanez® style AC adapters.
