TECH TIPS
Troubleshooting tips and solutions to common service problems
For models: PSWD112 Rev1 only * PSWD115 TIP# JBLTT2004-02

Subject: PSWD112/115 WIRING TO REMOTE VOLUME/CONTOUR/LED CONTROL PLATE A total of 9 wires travel from two Molex connectors on amplifier PCB to 334344-001 Control plate. That control panel is attached by two screws on the inside of the cabinet; the woofer must be removed. The wire cluster is glued into the cabinet opening at the rear of the control panel. The hot melt glue has to be cut out and pried out, then the wire cluster should be re-glued after the control panel is serviced, for air integrity. 1) Two Black sheathed cables, each containing wire colors: Black or Blue White Red 2) Three separate wires: Red White Gray At the Control Plate: Volume pot: Black or Blue, White, Red Contour Switch: Black or Blue, White, Red Power LED: Gray, Red Contour LED: White, Black w/ 10k resistor

* Rev1 version of the PSW-D112 subwoofer is easily identified by the absence of Center channel Input and Output connectors, and is missing the"Direct Out" RCA connector.
