TSS-SUB4000 CONNECTIONS If you have a Dolby* Digital or DTS® receiver/processor with a low-frequency-effects (LFE) output: If your receiver/processor has subwoofer outputs for the left and right channels: • Set Low-Pass Switch to Off. • Set Low-Pass Switch to On. NOTE: In this case, you do not need to use a Y connector. Simply connect the LFE output on your receiver/processor to either the left or right input on the subwoofer.
TSS-SUB4000 OPERATION Power On Low-Pass Selector Plug your subwoofer’s AC cord into a wall outlet. Do not use the outlets on the back of the receiver. If you have a Dolby Digital or DTS processor/receiver, the Crossover Frequency is set by the processor/receiver. Consult your owner’s manual to learn how to view or change this setting. In this case, the Low-Pass Selector £ should be set to “Off”. We strongly recommend this setup method.

TSS-SUB4000 NOTICE The main power transformer (toroid) part# 150-r1107008 in the TSS-SUB4000 is not mounted in the amplifier inside the amp cover, but mounted in the cabinet in a separate location. Replacement: To replace the power transformer, it is necessary to remove the woofer from the cabinet. The mounting bolt and transformer itself is mounted on an internal brace; both are accessible through the woofer opening. Instructions for woofer removal can be found on the exploded view, page 7.
