Logitech Z5500 Wiring — Diagram Exclusive
The proprietary pinouts, the infamous 6-pin DIN cable, and the color-coded speaker wire confusions have left thousands of users with expensive paperweights. If you have been searching for an exclusive , detailed wiring diagram that goes beyond the faded user manual, you have found it.
The Z5500 amplifier is a bridged design. Unlike standard receivers, both the positive and negative terminals are "hot." Do not ground any of these wires to the metal chassis.

Pins 5 and 6 carry the actual analog signal from your PC/console to the amplifier inside the subwoofer. If you have no sound but the pod lights up, your issue is likely Pins 5/6 (broken solder joint). Pins 3 and 4 are for the encoder wheel; if the volume jumps erratically, the Data lines have a short.
