Description
Boston’s PV500 subwoofer delivers the dynamic bass foundation that is essential for lifelike reproduction of movie soundtracks and music in the home. This attractive, powered subwoofer will complement any stereo or home theater surround sound system with its impressive bass output and compact size.
This subwoofer utilizes our rugged DCD™ (Deep Channel Design) bass unit designed in Boston’s state-of-the-art engineering facility in Peabody, Massachusetts. Every one is tested as it comes off the line to be within ±1dB of the lab reference unit, an incredibly tight tolerance. The amplifier has a built-in variable crossover that makes it easy to achieve a seamless blend with the main speakers, while a 24dB/octave low-pass filter prevents the subwoofer from being easily localized by ear, increasing placement flexibility. A crossover bypass function is provided for use with home theater electronics that perform their own bass management.
Because of its high-powered amplifier and computer-optimized tuning, the PV500 is capable of impressive deep bass and high output from a remarkably compact enclosure. In addition, it features BassTrac®, a proprietary Boston-designed circuit that tracks the input signal to the subwoofer and prevents its amplifier from being driven into audible distortion. The benefit: The bass stays clean and strong at any listening level.
Auto on-off amplifier switching and easily accessible controls make the PV500 subwoofer as convenient to use as it is exciting to listen to.

Connections
NOTE: Power is always supplied to the subwoofer electronics unless it is unplugged.
The auto-on circuitry only activates or deactivates the power amplifier. Make sure your subwoofer and receiver are unplugged when making the connection.
Line level: Use one of the “line level in” jacks with most systems. These inputs accept the line level signal from your receiver’s subwoofer output. When using the “use crossover control” input, the subwoofer’s circuitry filters out the high frequencies and sends the remaining low frequencies to the subwoofer power amplifier.
Speaker level: Use these high-level terminals with receivers that do not have subwoofer output. The speaker inputs accept both left and right channel speaker signals from your receiver.
How to Connect Using the Speaker Terminals
We recommend 18-gauge wire or thicker for runs up to 15 feet (4.5m), and 16-gauge wire or thicker for longer runs.
Separate the first few inches of the wire conductors. Strip off 1⁄ 2-inch (13mm) of insulation from the ends of each speaker wire to expose the two conductors and tightly twist the wire strands.
WARNING: To prevent electrical shock hazard, always switch off the amplifier or receiver when making connections to the speaker.
When making all connections, be sure to connect the + (red) on the speaker to the + (red) on the amplifier, and the – (black) on the speaker to the – (black) on the amplifier.

IMPORTANT: Typically, one side of the wire is smooth. Connect this side to the – (black) connection.
The other side has a rib or stripe. Connect this to the + (red) connection.
Using the spring terminal posts: The spring terminal posts permit easy connection to banana plugs, spade lugs, and bare wire.
Push the the top of the terminal down by approximately 1⁄4-inch (6mm), exposing the hole. Insert the wire in the hole and release the terminal.

Connecting the Subwoofer to Digital Home Theater Systems
Digital 5.1, 6.1 and 7.1 home theater electronics dedicate one channel (the “.1”) to reproduce the special low-frequency (LFE) information (such as explosions and thunder) contained in digitally-encoded soundtracks.
Select ”subwoofer-yes“ from your receiver’s set-up menu. Hooked up this way, the receiver’s amplifier is relieved of having to reproduce the difficult low bass signals that can drive the receiver into audible distortion.
Use an RCA cable (not included), as shown, to connect your digital receiver’s subwoofer output to the subwoofer.
Connect the other end to the PV500 jack labeled “bypass crossover control” underneath “line level in”.

SUBWOOFER OUT
BACK OF RECEIVER
If you do not wish to run RCA cables to your subwoofer, you may use speaker wire to connect the subwoofer in parallel with your main speakers (see diagram below). The subwoofer does not present any additional load to your receiver.
Select “subwoofer-no” from your receiver’s set-up menu. This sends the LFE signal to the main left and right speakers, and thus, to the subwoofer. Consult your receiver’s owner’s manual for more details.
When using the speaker wire hookup, the subwoofer’s built-in crossover is engaged. As a starting point, set the crossover control on the subwoofer about 10Hz higher than the lower limit of your main speakers’ bass response (for Boston Acoustics front speakers, refer to the included “Optimal Crossover Settings...”sheet). 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.

Connecting the Subwoofer to Stereo or Dolby® Pro Logic® Systems
For stereo or Dolby Pro Logic systems, the easiest method is to use the same speaker wire connections as shown on page 5.
You may also use the “sub out” connection from your receiver to the input on the subwoofer marked use crossover control. When using speaker wire or the use crossover control input, the subwoofer’s built-in crossover is engaged. As a starting point, set the crossover control on the subwoofer about 10Hz higher than the lower limit of your main speakers’ bass response (for Boston Acoustics front speakers, refer to the included “Optimal Crossover Settings...”sheet). Finetune 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.
