22.Servicing. Do not attempt to service this product yourself, as opening or removing covers may expose you to dangerous voltage or other hazards. Refer all servicing to qualified service personnel.
SPEAKER PLACEMENT
•As a general rule, bass response increases as a subwoofer is placed closer to a wall. Therefore, bass output is maximized when the subwoofer is placed in a corner.
•It is also recommended that the subwoofer be positioned along the same wall as the front loudspeakers.
Low-frequency sounds are normally omnidirectional, meaning the listener can’t tell where they
are generated from. However, frequencies between 75Hz – 150Hz can be localized, especially at higher volume levels. Positioning your subwoofer as recommended will provide the most natural soundstage and imaging from your loudspeaker system.
Remember that these are just guidelines. Since every listening room is different, JBL strongly recommends experimenting
with the positioning of your subwoofer to obtain the most pleasing results in your room. One technique that can help you find the ideal subwoofer location is to temporarily place the subwoofer near the main listening location. Then move around the room and determine where you hear the most pleasing bass performance. This would then be the ideal location for the subwoofer.

SPEAKER CONNECTION
When we designed the E150P and E250P powered subwoofers, our goal was to offer the user the best possible performance combined with the most flexible and complete installation options. Please look over the following three examples to determine which description best matches your system and follow the corresponding hookup instructions.
To use the binding-post speaker terminals with bare wire, unscrew the collar until the hole through the center post is visible under the collar. Insert the bare end of the wire through the hole in the post, then screw the collar back down until the connection is tight. The holes in the center of the collars are intended for banana-type connectors.
To comply with European CE certification, these holes are blocked with plastic inserts at the point of manufacture.To use banana-type connectors requires the removal of the inserts. Do not remove these inserts if you are using the product in an area covered by the European CE certification.
ANALOG RECEIVER/PROCESSOR – SPEAKER LEVEL CONNECTIONS
Use this installation method with an analog receiver/ processor that does not have digital processing or bass management, and also does not have a subwoofer output or a volume-controlled preamp (line-) level output:
Connect your receiver or amplifier’s front left and right speaker terminals to the left and right terminals on the subwoofer that are marked “High Level In.” Connect the left and right terminals on the subwoofer that are marked “High Level Out” to the cor-responding terminals on the back of your front left and right speakers.
Connect your receiver or amplifier’s center, left and right sur- round-speaker terminals to the corre-sponding terminals on the back of your center, left and right surround speakers.
