Page 4: Introduction
Introduction Congratulations! By purchasing our 500-Watt amplifier for your Hsu Research Subwoofer, you have chosen one of the best subwoofer and amplifier combinations in the market. Our amplifiers have been optimized to yield the highest performance attainable from our subwoofers so you can be assured that your experience with our product will be a pleasant one. -

Amplifier Placement Our preference is to place the Hsu amplifier close to your main amplifier and/or receiver/processor. This allows you to use short interconnects. Make sure you have adequate ventilation around the amplifier. -
Page 7: Connecting
Connecting To Your System Connecting to a Dolby Digital or DTS system All Dolby Digital and/or DTS processors have subwoofer/LFE outputs. If you decide to use the crossover in the processor, connect your receiver or processor subwoofer/LFE out to the line level input of your 500-Watt amplifier via a Y adapter (splitter) to both line-in on the back of the 500-Watt amplifier. - Page 8 Connecting to a system with separate components If you have separate preamp and power amp, and wish to keep the bass from the main speakers, connect the front left and right preamp outputs to the line-level in of the 500-Watt amplifier. Next, connect from the out high pass of the 500-Watt amplifier to the inputs of your power amplifier.
- Page 9 If you only have one set of pre-amp output on your receiver/processor and need to send the signal to the subwoofer amplifier as well as another amplifier, first send the signal to the subwoofer amplifier as described above and then use either the out hi pass or out all pass outputs on the subwoofer amplifier to send the appropriate (high-pass filtered or full frequency) signal to the second amplifier.

These plug-in modules set the crossover frequency. We have optional modules for other crossover frequencies. See Appendix A for available frequencies. To purchase extra crossover modules, please contact Hsu Research or visit our website at www.hsuresearch.com. Phase Switch Depending on the absolute phase of your main speakers and amplifier, and the relative distance of the subwoofer and the main speakers from the listening position, the bass in the crossover region may be smoother if you reverse the phase of the subwoofer relative to the main speakers. -
Page 12: Volume Level
Using built-in test tones of a receiver/processor, or by using a test CD/DVD (such as the CD-R that comes with Hsu subwoofers), the user should match the levels of all of his or her speakers. We recommend using an SPL meter such as the Radio Shack unit (use "C" weighting and slow settings). -
