The back of the Control Pod looks like an old VGA monitor plug. This is where your sources connect.

The Logitech Z-5500 is a legendary 5.1 surround sound system. Released in 2004, it still rivals modern home theater setups. However, its proprietary connectivity often leaves users stranded when cables fail or components break.

Since Logitech discontinued the Z5500 in 2012, you cannot buy official cables. Use your exclusive wiring knowledge to source alternatives:

The connection between the control pod and the subwoofer uses a DB15 connector. The pinout varies slightly between versions (Pre-636 vs. Post-636 PID), but the general signal map is as follows: Description Subwoofer In Audio signal for the sub 2 Left Front In Audio signal for left front satellite 3 Audio signal for center speaker 4 Left Rear In Audio signal for left surround 5 Right Rear In Audio signal for right surround 6 Right Front In Audio signal for right front satellite 7 Enable / Standby High (+5V) to turn system ON 8 Audio and power common ground 10 Main DC power for the pod from the sub 13 Secondary ground line 15 +18V Power High-voltage supply for internal pod regulation 2.

The satellite speakers connect to the back of the subwoofer via standard spring clips. However, inside the enclosure, these clips map to a specific wiring harness connected directly to the amplifier PCB. If you are replacing a broken spring-clip terminal block, use this color-code mapping: Positive (+) = White | Negative (-) = Black Front Right Sat: Positive (+) = Red | Negative (-) = Black Center Sat: Positive (+) = Green | Negative (-) = Black Rear Left Sat: Positive (+) = Brown | Negative (-) = Black Rear Right Sat: Positive (+) = Blue | Negative (-) = Black Below is the definitive, tested pinout for the

This is the central unit that houses the power amplifier for the subwoofer and the control circuitry for the system. It connects to the computer or audio source and controls the entire system.

3. How to Connect a Subwoofer Output to Z-5500 Without a Pod

Are you trying to or bypass a dead control pod ? Do you have a multimeter and a soldering iron available? Released in 2004, it still rivals modern home theater setups

The Logitech Z5500 is a popular 5.1 surround sound speaker system, but its complex wiring can be overwhelming for some users. To simplify the setup process, we introduce "EasyConnect" - an exclusive wiring diagram feature that makes connecting your Z5500 system a breeze.

Here is the exclusive, simplified guide to doing it right:

The most common failure point is the DB15 cable connecting the control pod to the subwoofer. If you want to bypass the control pod and use your own pre-amplifier or PC sound card to drive the subwoofer directly, use this pinout configuration.

Check the main power fuse. If the system is dead, it could be a blown fuse inside the subwoofer unit. If the fuse blows repeatedly, you likely have a failed transformer.

If you are building a custom replacement cable or repairing a severed control pod wire, use the following high-density DB15 pinout matrices.
