14、put jacks for the left and right channels or you have a separate preamp/processor and power amplifier: This method of hookup can offer the highest level of performance for your complete loudspeaker system. Your subwoofer incorporates an adjustable high-pass crossover in addition to a variable low-pa

15、ss crossover. When hooked up as shown below, the subwoofer will limit the low-frequency information that is returned to your receiver/amplifier. Your receiver/amplifier does not need to waste valuable power reproducing the low frequencies. In addition, since no low-frequency information is being sen

16、t to your main loudspeakers, they are able to reproduce mid and high frequencies with greater clarity.

19、Initially set the HPSs Gain control to the “O” position. 2.Initially set the HPSs Crossover control to the 100Hz position. 3.Plug your HPSs AC cord into a wall outlet. Do not use the outlets on the back of the receiver. 4.Turn on your HPS sub by pressing the power button on the center of the front p

20、anel. 5.Turn on your entire audio system and start a CD or movie sound track at a moderate level. 6.Turn your HPSs Gain control (Figure 2) up to the “5” position (half way). If no sound emanates from the subwoofer, check the AC-line cord and input cables. Are the connectors on the cables making prop

21、er contact? Is the AC plug connected to a “live” receptacle? Has the power button been pressed to the “on” position? (Note: A green indicator on the front panel will light when the power is on.) Once you have confirmed that the subwoofer is active, proceed by playing a CD, record or cassette. Use a

22、selection that has ample bass information. 7.Set the overall volume control of the preamplifier or stereo to a comfortable level. Adjust the subwoofers Gain control (Figure 2) until you obtain a pleasing blend of bass. Bass response should not overpower the room but rather be adjusted so there is a

23、harmonious blend across the entire musical range. Many users have a tendency to set the subwoofer volume too loud, adhering to the belief that a subwoofer is there to produce lots of bass. This is not entirely true. A subwoofer is there to enhance bass, extending the response of the entire system so

24、 the bass can be felt as well as heard. However, overall balance must be maintained or the music will not sound natural. An experienced listener will set the volume of the subwoofer so its impact on bass response is always there but never obtrusive. 8.Crossover Control (Figure 2) The Low-Pass contro

25、l determines the highest frequency at which the subwoofer reproduces sounds. If your main speakers can comfortably reproduce some low-frequency sounds, set this control to a lower frequency setting, between 50Hz 100Hz. This will concentrate the subwoofers efforts on the ultradeep bass sounds require

26、d by todays films and music. If you are using smaller bookshelf speakers that do not extend to the lower bass frequencies, set the low-pass crossover control to a higher setting, between 120Hz 150Hz. 9.The Phase Control (Figure 2) determines whether the subwoofer speakers piston-like action moves in

27、 and out with the main speakers, 0, or opposite the main speakers, 180. Proper phase adjustment depends on several variables such as room size, subwoofer placement and listener position. Adjust the phase switch to maximize bass output at the listening position. 10.The EQ switch, located on the front

28、 panel, optimizes the subwoofers performance for both movie and music listening. When in the “Video” position, a special EQ circuit is activated, enhancing low frequencies by approximately 3dB at 32Hz and delivering the full impact and excitement of todays movie soundtracks. When in the “Audio” posi

29、tion, the subwoofer provides the accurate and linear frequency response that is ideal when a natural tonal balance is desired for music listening. 11.Remember: every system, room and listener is different. There are not necessarily any right or wrong settings; any setting you choose will result in e

30、xcellent performance. Should you decide to fine-tune your system for optimum performance, be patient and trust your ears. It will be worth the effort involved to fully “tweak” your system. 4 4 2 3 A WORD OFADVICE The low-frequency Crossover and Volume controls may be set anywhere within their rotati

31、on. However, it will be a most unusual circumstance if you have to set the Volume control completely clockwise. This may indicate an unbalanced condition in your system (too much bass), that the system is in an especially large room, or that speaker placement may be incorrect. Try several other loca

32、tions before concluding that the Volume control must be set at maximum. OVERDRIVEPROTECTION Automatic limiting circuitry helps prevent overdriving a connected subwoofer by softly clipping the input signal if it exceeds a predetermined threshold. Depending on the level, you may or may not hear slight

33、 distortion on musical peaks. This protection is completely automatic, with no user adjustments. However, if you do hear distortion continuously while playing music, the input signal level (feeding the HPS) may be too high and should be lowered. If this doesnt solve the problem, check the connection

34、s and that the other components in the audio chain are operating properly. A WORDABOUTTONECONTROLS The tone controls on your electronic components (preamplifier, receiver, etc.) should be used with the utmost discretion. Excessive boost can create severe power demands on your power amplifier. Maximu

35、m bass boost can create a demand for literally hundreds of watts in the bass region, whereas in the “flat” position, or with the tone controls switched out of the system, your average listening level may be impressively and realistically loud at fewer than 10 watts. The remaining power capacity requ

36、ired is on reserve for power peaks on sharp transients and powerful crescendos. HPS500 PARTS LIST AMP ASSEMBLY #333777-001 Power supply PCB Part #Description Qty Ref.
