Audio Connections
The MPX 500 produces effects from either mono or stereo sources. With mono sources, the dry signal
appears, along with audio effects, at both outputs. For instruments and sources with stereo outputs,
use both inputs. We recommend using the outputs in stereo whenever possible, but if mono output
is required, use either output jack.
Footswitch
A footswitch connected via the rear-panel footswitch jack allows control of Tap and Bypass. A
momentary footswitch can be wired to a tip-ring-sleeve connector. A stereo Y-connector allows two
identical single switches to be used.
Power off the MPX 500 before plugging in the footswitch. (Otherwise, Bypass will be enabled.)
MIDI
Two 5-pin DIN MIDI connectors
are provided for MIDI IN and soft-
ware selectable MIDI OUT/THRU.
POWER
Standard 3-pin IEC power
connector; 100-240V, 50-
60Hz automatic switching to
correct voltage range.
OUTPUT
Balanced Tip-Ring-Sleeve and
XLR stereo outputs.
FOOTSWITCH
1/4" TRS connector, for momentary con-
tact footswitch, allows footswitch control
of front panel Tap and Bypass functions.
