Installation and Setup of the AR PL900T Tower Speakers

How to Place System Components 

The optimum listening position is at the tip of the so-called “stereo triangle”(Fig.1). The equilibrium between the right and left stereo channels is best in this position, providing the most balanced and realistic sound reproduction.Your AR speakers will operate most efficiently when they are located in parts of the room with “hard” acoustics, i.e., areas including hard, smooth surfaces such as walls and wooden furniture. The speakers should radiate the sound from this hard area into the “softer” parts of the room containing sound-absorbing elements such as upholstered furniture, carpets and so on. Make sure that there are no sound-absorbing obstacles between the speakers and your listening position, as this will muffle the sound and impair your listening pleasure.Your PL900 Series speakers are fully shielded for use in audio/video applications. This allows you to place any of the speakers next to the television without affecting picture quality. If you are using other speakers, be sure to locate them at least 3 feet away from the television to avoid interference to the set’s picture. The speakers should be installed at least 1 foot away from the side walls. This prevents exaggerated “booming” bass and helps to produce more balanced, detailed sound reproduction.If possible, the speakers should be installed so that the tweeters are on the same level as the listener's ears. If you install the speakers in a wall unit, take care to ensure that the fronts of the speakers are flush with the front of the wall unit.

Connecting the Surround Speakers

Strip the insulation from the connection cable ends and twist the ends tightly or tin them with solder. Then insert the ends in the connection terminals and secure them. Caution: Take care to ensure that the speaker cables are connected with the correct polarity!Connect the negative amplifier output terminal (black) to the negative connection terminal of the AR speaker (also black). Proceed in the same way to connect the positive terminals, which are normally red. Standard speaker connection cables normally have a colored marking or indentation in the surface of the insulation to distinguish the two leads from one another.

IMPORTANT: Always connect the red (+) terminal on the Receiver to the red (+) terminal on the corresponding Speaker i.e. Front Left. Connect the corresponding black (-) terminal on the Receiver to the black (-) terminal on the same Speaker. Continue until all of the speakers have been connected in this manner.

Connection with Speaker Wire:

Tower Stand-Mounting with Wire: Screw the provided lock-nuts onto both threaded ends of the stand tube. Thread end of your speaker wire through the stand tube starting by fishing the wire through the hole on the top of the tube. Screw the stand tube into the base and tighten. use the threaded lock nut to tighten the tube against the base making sure the wire management hole is facing the back of the stand. Connect the speaker to the stand by turning the speaker clockwise until it is tight and lined up with the base. Tighten the lock-nut against the speaker and lock it into place. Connect the speaker wire to the 5-way binding posts making sure the positive and negative wires are connected properly. Failure to match the polarity will result in the speakers being out of phase.

Tower Wall-Mounting: After marking the level location on the wall, mount the wall plate to the wall using the proper hardware for your type of wall. Make sure your screws are securely mounted into the wall studs or that the proper anchors are used for a hollow wall application. Securely fasten the bracket heads to the back of the speaker using the included hardware. Connect the two bracket components together by placing the mounting pins on the wall plate into the bracket heads mounted to the back of the speaker. Adjust the speaker positioning by swiveling left or right to create a focused listening position.
