Output Level Selector ( —20 db + 4 db)
Facilitates SPX90 II source/line level (sensitivity)

Output Jacks (L and R)
These are standard mono 1/4” phone jacks which
deliver the direct and effect signal to subsequent
mixing or amplification equipment. Since the
SPX90 II offers stereo output, we recommend that
the output signal be fed in stereo to a stereo sound
system in order to take full advantage of the superb
stereo effects provided. Output impedance is 600
ohms.
