To use the Z-5500 subwoofer with a standard AV receiver, you must ground the enable pins (6, 7, 8, and 13) to wake the internal amplifier. Pin 2 receives the LFE signal from the receiver via an RCA-to-DB15 custom cable. Active Subwoofer Conversion:
Slide heat-shrink tubing over every soldered joint. Ensure that Pin 11 (+18V) and Pin 12 (-18V) are cleanly cut back and insulated with heat shrink. If these pins accidentally touch the audio lines or the ground casing, the internal power supply rail fuses will immediately blow, or the amplifier ICs will fry. Satellite Speaker Configuration and Impedance Mapping
If your control pod has failed, or if you want to use the Z-5500 subwoofer and amplifier with a third-party AV receiver, you need to know what each pin on the DB15 connector does.
