NHT SW10, SW12 user manual Hi-Level

•Preamps with Line Out jacks: connect one pair of Line Out cables to your main amp to power your main L & R speakers, and a second pair to the SW10II OR SW12 LINE LEVEL INPUT. If your preamp has only one pair of Line Out jacks, you can use a pair of "Y" connector cords, available through your NHT dealer.

•Amps and receivers with Pre-Out jacks: connect the SW10II OR SW12 from the Pre-Out into the SW10II OR SW12's Line Input.

2) Hi-Level

Use if:

Your receiver has no Pre Out or Subwoofer/LFE Out jacks

To connect for a High-Level signal (Fig. 4), use two addi- tional pairs of speaker cables, and connect as follows:

•For amps and receivers with separate A and B speak- er outputs, connect one pair of speaker cables from your receiver's Speaker A outputs to your main L & R speak- ers, and a second pair from your receiver's Speaker B outputs to the SW10II OR SW12's High-Level Input. Use this method only if both A & B speaker outputs can oper- ate simultaneously.

•For amps and receivers with only one set of speaker output terminals, simply feed the same signal, in parallel, to both your main L & R speakers and the SW10II OR SW12. Connect one pair of speaker cables from your

component's speaker output terminals to the L & R speakers, and a second pair from the same output ter- minals to the SW10II OR SW12's High-Level input. The SW10II OR SW12's input does not present a significant load to the receiver, and will not compromise its output to the L & R speakers. If you find that your receiver will not accommodate more than one cable per output terminal, check with your NHT dealer for alternative methods of connection.

With all signal connections complete, it is now time to apply AC power. Plug the power chord into the power inlet in the back of the subwoofer, plug the other end into into the wall outlet and switch the subwoofers power to the ON position.
