system or neighbors are disturbed by ultra low bass.

6. High Level Inputs

Under normal conditions, the preferred connection is through the Line Level inputs. If this is difficult or not possible in your system, then you can use the High Level inputs. Also, if you experience excessive noise or hum with the Line Level inputs, often a simple change to the High Level inputs will result in a lower background noise level.

Connect to the speaker-level output of your amplifier or receiver using speaker wire (see page 14). They can accept bare wire, banana, dual-banana or spade connections.

Your amplifier or receiver MUST have common grounded outputs, or it will be damaged if connected to these High Level inputs.

7. Line Level Inputs

Connect with RCA type patch cords to the line level outputs of your receiver or preamp. Here are two examples:

If your preamplifier or receiver has a single sub/LFE output, connect it to the subwoofer’s left input jack (see page 11). There is no need to use the subwoofer’s right input jack.

If you want to run your main/satellite speakers full range, use a “Y” adapter at the preamplifier outputs (see page 12). In this way, you can send the preamplifier’s full-range output signal to your main amplifier and to the subwoofer at the same time.

8. High Pass Outputs

Line level high-pass output signals are available at these jacks. These are active whenever a signal is present at the inputs of the subwoofer. The high- pass crossover is a passive network with a fixed crossover frequency of

70 Hz and a 6 dB per octave slope.

We recommend using this high-pass function with main/satellite speakers that are small and not designed to reproduce low frequencies. If your main speakers are capable of operating full range, then you will not need to use the high-pass function.

To use the High Pass outputs, connect the preamp outs of your preamp/ receiver to the subwoofer’s Line Level inputs using good quality RCA type patch cords. Then connect a second patch cord from the subwoofer’s High Pass outputs to the inputs of your main amplifier (see page 13). This will allow your main speakers to operate at frequencies above 70 Hz and the subwoofer to operate at frequencies below 70 Hz.

9. Line Fuse

The subwoofer is supplied with a conservative 4 amp slow-blow type fuse to protect the electronics.

Always unplug the power cord before inspecting or changing the fuse. Never use a fuse with a current rating more than 4 amps.

10. Power Cord

Plug into any 120 Volt 60 Hz outlet with a circuit rating of 8 amps or more (a typical home circuit is rated at 15 amps).

Never plug the power cord directly into 220-240 Volts AC as this will cause catastrophic circuit failure.
