Outputs

The PLX 1104 and PLX 1804 models are equipped with Speakon output

connectors for each channel. PLX 1802, PLX 2502, PLX 3102, and PLX 3602

models are equipped with Speakon and binding post output connectors.

Wiring connections are shown on the back of the chassis. Carefully note

the markings and maintain consistent loudspeaker polarity for optimum

system performance.

Speakon Output Connectors

If making Speakon cables, be sure to connect the loudspeaker wiring as

shown on the chassis. Channel 1’s Speakon provides 4-wire (Ch 1 + Ch 2)

connection; Channel 2’s Speakon provides 2-wire (Ch 2 only) connection.

Appendix A provides Speakon connection reference.

Stereo and Parallel Mode: Connect each loudspeaker to its own chan-

nel of the amplifier, as shown on the chassis label. The INPUT CONFIGU-

RATION switch must be set for STEREO or PARALLEL mode.

Bridge Mode (PLX1802/2502/3102/3602 models only): Use Channel 1’s

Speakon for Bridge mode output connection. Bridge mode configures the

channel pair to drive a single high-power loudspeaker load. The INPUT

CONFIGURATION switch must be set for BRIDGE mode. Use only Channel

1’s input and Gain control. Set Channel 2’s Gain control at minimum.

PLX 1802, PLX 2502, PLX 3102, and PLX 3602

Output Connectors: Do not use less than 2 ohm

impedance loads with these models.

PLX 1104 and PLX 1804 Output Connectors: Do

not use less than 4 ohm impedance loads

with PLX 1104 and PLX 1804 models.

Binding Post Connectors (PLX 1802/2502/3102/3602

models only)

Stereo and Parallel Mode: Connect each loudspeaker to its own

channel of the amplifier, as shown on the chassis label. The INPUT

CONFIGURATION switch must be set for STEREO or PARALLEL

mode.

Bridge Mode: Bridge mode configures the channel pair to drive a

single high-power loudspeaker load. The INPUT CONFIGURATION

switch must be set for BRIDGE mode. Use only Channel 1’s input

and Gain control. Set Channel 2’s Gain control at minimum.

OUTPUT TERMINAL SAFETY WARNING! Do not touch

output terminals while amplifier power is on. Make all

connections with amplifier turned off. Risk of hazard-

ous energy!
