Connecting the PV1000 to Digital 5.1 Channel Home Theater Systems NOTE: Power is always supplied to the subwoofer electronics unless it is unplugged. Make sure your subwoofer and receiver are unplugged when making the connections. Digital 5.1 home theater electronics dedicates one channel (the “.1” of 5.1) to reproduce the special low-frequency (LFE) information (such as explosions and thunder) contained in digitallyencoded soundtracks. Select subwoofer-yes from your receiver’s set-up menu.
Connecting the PV1000 to Dolby® Pro Logic® Systems For Dolby Pro Logic systems, check to see what kind of line level output your receiver or processor has. Most Pro Logic systems have a single sub out connection. Set the Center Channel Mode on the receiver to Normal. This diverts any bass in the center channel to the subwoofer, resulting in maximum system bass output. Line in Line out L / mono 115V 60Hz 7.
Setting the Crossover Control As a starting point, set the crossover control on the PV1000 about 10Hz higher than the lower limit of your main speakers’ bass response. Fine-tune the crossover setting by ear for the smoothest blend with your main speakers. The best setting of the crossover control will depend on speaker placement and personal preference.
Controls Front Panel Volume: Adjusts the sound level of the subwoofer. A typical setting is around 10 o’clock. Crossover (Hz): Adjusts the frequency of the low-pass filter for the subwoofer. Crossover Set/None: Engages or bypasses the PV1000’s built-in low-pass filter. Polarity (0° or 180°): Selects regular (0°) or inverted (180°) polarity for the subwoofer. Set this switch to provide the fullest, most dynamic bass.
Placement Place the subwoofer next to a wall or in a corner near your main speakers. Typically, the sound is best when the subwoofer is within 15 feet (5m) of the main speakers. However, the sharp 24dB/octave crossover roll-off permits placement farther from the main speakers if necessary. Since the ear is unable to localize the low frequencies of the subwoofer, the bass still appears to come from the main speakers. In most cases, the subwoofer may be placed anywhere in the listening room.
