OPERATION

1.Initially set the HPS’s Gain control to the “O” position.

2.Initially set the HPS’s Crossover control to the 100Hz position.

3.Plug your HPS’s 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 panel.

5.Turn on your entire audio system and start a CD or movie sound track at a moderate level.

6.Turn your HPS’s Gain control ❸ (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 proper 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, pro- ceed by playing a CD, record or cassette. Use a selection that has ample bass information.

7.Set the overall volume control of the preamplifier or stereo to a comfortable level. Adjust the subwoofer’s Gain control ❸ (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 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 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 ❶ (Figure 2) – The Low-Pass control 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 subwoofer’s efforts on the ultradeep bass sounds required by today’s 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 ❷ (Figure 2) determines whether the subwoofer speaker’s piston-like action moves in and out with the main speakers, 0˚, or opposite the main speakers, 180˚. There is no correct or incorrect setting. 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. Remember, every system, room and listener is different. There are no right or wrong settings; any setting you choose will result in excel- lent 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.
