A standard 3.5mm stereo jack (usually labeled 'AUX') for connecting portable music players, phones, or a second PC.
Solder all outer ground shields of the audio cables together and tie them to .
Pin 14 outputs a hot +18V DC rail directly from the subwoofer. Shorting this pin to any audio input or logic pin will permanently fry the subwoofer's pre-amp circuitry.
This mod disables the volume knob and digital decoding. You must control volume at the source. logitech z5500 wiring diagram exclusive
The official diagram showed power, ground, front left/right, center, rear, and sub pre-out. Simple. But Leo knew the Z-5500 was deceptive. There was a sixth sense in that cable: a bidirectional data line. When you turned the pod’s volume knob, it didn’t send an analog signal—it sent a packet of data. The sub received it, acknowledged it, then woke up the amplifiers.
Traces directly to the single high-power bridging amplifier circuit.

These units feature a detachable control pod cable that plugs into a DB15 port on both the pod side and the subwoofer side. The internal amplifiers utilize a slightly higher voltage tolerance on the logic board.
This pinout differs from a standard audio cable because it carries high-voltage DC power (+18V, -18V) and logic control lines.
Note: Wire colors can vary slightly by manufacturing year, but the following is the standard for most revisions.
