MIC Input – XLR Input Jack for microphones. To use the MIC input, set the
LEFT INPUT switch to MIC. Flip the PHANTOM POWER switch to ON to apply a
phantom power voltage of approximately +45VDC to the MIC input. Please
ensure the microphone you are using can withstand phantom power before
enabling the switch. In particular, phantom power is known to possibly damage
ribbon microphones. The input impedance presented at the XLR input is 10kΩ.
R Input – ¼” Right Instrument/Line Input Jack. Plug the output of your
instrument or another effects pedal into this jack. Use this jack for stereo
recording or for recording a second instrument. The input impedance presented
at this jack is 1MΩ. The maximum allowable signal level into this jack is +11
dBu, it is an unbalanced input.
L/MONO Output – ¼” Left Output Jack. The Left output signal is sent through
this jack. The dry signal present at the Left input – whether the ¼” input or the
MIC input – will be output on the L/MONO Output jack. The left signal on Loop
A, Loop B, and the Rhythm loop come out of the L/MONO Output jack. The
source impedance of the L/MONO Output is approximately 400Ω.
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 on the R Output
jack. The right signal of Loop A, Loop B, and the Rhythm loop come out of the R
Output jack. The source impedance of the R Output is 400Ω.
FC Jack – ¼” Foot Controller Jack. Insert a standard, mono ¼” instrument
cable into the FC jack. Connect the other end of the cable to the optional 22500
Foot Controller. The 22500 Foot Controller can be used to scroll up or down
through the 22500’s loop banks. Press and hold the footswitches on the Foot
Controller to jump by 10 through the banks. The 22500 does not accept general
purpose footswitch boxes at its FC jack. Use the 22500 Foot Controller only.
9V Power Jack – Connect the output plug of the supplied AC Adaptor into the
9VDC power jack on the rear panel of the 22500. The 22500’s current
requirement is 240mA at 9VDC. The polarity of the power jack is center negative.
The maximum allowable power supply voltage is 10.5 VDC.
