14、f performance for your complete loudspeakersystem. Your subwoofer incorporates an adjustable high-pass crossover in addition to a variablelow-pass crossover. When hooked up as shown below, the subwoofer will limit the low-frequencyinformation that is returned to your receiver/amplifier. Your receive

15、r/amplifier does not need towaste valuable power reproducing the low frequencies. In addition, since no low-frequencyinformation is being sent to your main loudspeakers, they are able to reproduce mid and highfrequencies with greater clarity.LOWLEVELOUTLOWLEVELINLR120Hz160Hz80HzRECEIVER/AMPLIFIEROR

Do not use the outlets on the back of the r

19、eceiver.4.Turn on your HPS sub by pressing the power button on the center of the front panel.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 soundemanates from the subwoofer,

20、check the AC-line cord and input cables. Are the connectorson the cables making proper contact? Is the AC plug connected to a “live” receptacle? Hasthe power button been pressed to the “on” position? (Note: A green indicator on the frontpanel will light when the power is on.) Once you have confirmed

21、 that the subwoofer isactive, proceed by playing a CD, record or cassette. Use a selection that has ample bassinformation.7.Set the overall volume control of the preamplifier or stereo to a comfortable level. Adjustthe subwoofers Gain control (Figure 2) until you obtain a pleasing blend of bass. Bas

22、sresponse should not overpower the room but rather be adjusted so there is a harmoniousblend across the entire musical range. Many users have a tendency to set the subwoofervolume too loud, adhering to the belief that a subwoofer is there to produce lots of bass.This is not entirely true. A subwoofe

23、r is there to enhance bass, extending the response ofthe entire system so the bass can be felt as well as heard. However, overall balance mustbe maintained or the music will not sound natural. An experienced listener will set thevolume of the subwoofer so its impact on bass response is always there

24、but never obtrusive.8.Crossover Control (Figure 2) The Low-Pass control determines the highest frequencyat which the subwoofer reproduces sounds. If your main speakers can comfortably reproducesome low-frequency sounds, set this control to a lower frequency setting, between50Hz 100Hz. This will conc

25、entrate the subwoofers efforts on the ultradeep bass soundsrequired by todays films and music. If you are using smaller bookshelf speakers that donot extend to the lower bass frequencies, set the low-pass crossover control to a highersetting, between 120Hz 150Hz.9.The Phase Control (Figure 2) determ

26、ines whether the subwoofer speakers piston-likeaction moves in and out with the main speakers, 0, or opposite the main speakers, 180. Proper phase adjustment depends on several variables such as room size, subwooferplacement and listener position. Adjust the phase switch to maximize bass output at t

27、helistening position. 10.The EQ switch, located on the front panel, optimizes the subwoofers performance forboth movie and music listening. When in the “Video” position, a special EQ circuit isactivated, enhancing low frequencies by approximately 3dB at 32Hz and delivering thefull impact and excitem

28、ent of todays movie soundtracks. When in the “Audio” position,the subwoofer provides the accurate and linear frequency response that is ideal when anatural tonal balance is desired for music listening.11.Remember: every system, room and listener is different. There are not necessarily any rightor wr

29、ong settings; any setting you choose will result in excellent performance. Should youdecide 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.4423A WORD OFADVICEThe low-frequency Crossover and Volume con

30、trols may be set anywhere within their rotation.However, it will be a most unusual circumstance if you have to set the Volume control completelyclockwise. This may indicate an unbalanced condition in your system (too much bass), that thesystem is in an especially large room, or that speaker placemen

31、t may be incorrect. Try severalother locations before concluding that the Volume control must be set at maximum.OVERDRIVEPROTECTIONAutomatic limiting circuitry helps prevent overdriving a connected subwoofer by softly clippingthe input signal if it exceeds a predetermined threshold. Depending on the

32、 level, you may or may not hear slight distortion on musical peaks. This protection is completely automatic, withno 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 doesntsol

33、ve the problem, check the connections and that the other components in the audio chain areoperating properly. A WORDABOUTTONECONTROLSThe tone controls on your electronic components (preamplifier, receiver, etc.) should be usedwith the utmost discretion. Excessive boost can create severe power demand

34、s on your poweramplifier. Maximum bass boost can create a demand for literally hundreds of watts in the bassregion, whereas in the “flat” position, or with the tone controls switched out of the system, youraverage listening level may be impressively and realistically loud at fewer than 10 watts. The

35、remaining power capacity required is on reserve for power peaks on sharp transients andpowerful crescendos.HPS500 PARTS LIST AMP ASSEMBLY #333777-001 Power supply PCB Part #Description Qty Ref.
