Yes. Using the pinout guide above, you can create a testing rig to send specific signals and voltages to power on the amp and test channel functionality. logitech z5500 wiring diagram exclusive
Solder all outer ground shields of the audio cables together and tie them to . Let’s solve these permanently
The pins are numbered as follows on the DB15 Female connector that plugs into the subwoofer, with the "D" shape of the connector used for orientation [6†L19-L21]: Solder all outer ground shields of the audio
These units feature a hardwired cable that goes directly into the control pod, with a DB15 plug only on the subwoofer end. Pin 12 (Sense) is actively monitored by a micro-controller. If Pin 12 does not read the correct impedance relative to ground, the internal amplifier system will lock down and refuse to power on, even if Pins 8 and 11 are bridged.
