Rear Panel Connections

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.

DIGITAL I/O

RCA S/PDIF connectors.

INPUT

Balanced Tip-Ring-Sleeve and

XLR stereo inputs.

LCD Contrast

Adjusts display contrast.

Use only a Tip/Ring/Sleeve connector.

Using a Tip/Ring connector will short the ring

and sleeve, which can hang the unit.
