WARNING The lightning flash with arrowhead, within an equilateral triangle, is intended to alert the user to the presence of uninsulated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute risk of electric shock to persons.
IMPORTANT SAFETY INSTRUCTIONS LIGHTNING – For added protection for the subwoofer or control module during a lightning storm, or when it is left unattended and unused for long periods of time, unplug them from the wall outlet. This will prevent damage to the subwoofer or control module due to lightning and powerline surges. READ INSTRUCTIONS – All safety and operating instructions should be read before the subwoofer is operated.

SYSTEM CONFIGURATION The P300 HD may be used with virtually any system. Typically, you will use the SUBWOOFER or LFE output from your receiver or processor to supply signal to the P300. You may also use the speaker outputs from a receiver or amplifier that does not have a separate SUBWOOFER output. One P300 is sufficient for most rooms. For higher output or very large rooms, a second P300 may be used. ATTACH THE FEET The P300 HD is supplied with screw-on feet to assure a stable, level mounting.
PLACEMENT The output of the subwoofer is strongly affected by room boundaries such as the floor and walls. The evenness of the response throughout the room is also affected by the placement. Because each room has its own unique acoustic character, experimentation with placement is essential to get the best overall performance. Each floor or wall boundary will increase the output in the listening area.
WIRING The wiring you need depends on the signal source you are using. The most common source is a surround processor with a dedicated SUBWOOFER or LFE output. Use a highquality shielded cable with a Phono plug on each end from the surround processor’s output to either the L or R input jack of the P300 HD. It is also possible to connect the P300 HD to a stereo receiver or preamplifier with Left and Right full range outputs.
ADJUSTMENTS With a surround processor: When using the subwoofer output of a surround processor, set the P300 HD’s frequency control fully clockwise. Try the Phase switch in both positions and leave it in the position that yields the most bass. If there is no audible difference between the two positions in your room, leave the switch in the 0-degree (out) position. Your surround processor has a variety of adjustments to optimize the sound based on the speakers’ capabilities and placement.
