Although there are two outputs for the center channel, only one connection is typically required. As the two outputs are identical, either one may be used and the other left open.
Subwoofer connections are made using the SUBWOOFER Outputs d. When using a powered subwoofer, connect BOTH the left and right output subwoofer outputs to the respective left and right
Once the center channel speaker is installed, position the left and right front speakers so that they are as far away from one another as the center channel speaker is from the preferred listening position. Ideally, the front channel speakers should be placed so that their tweeters are no more than 24″ off center from the tweeter in the center channel speaker.

line level inputs on your subwoofer. As the PT2500 subwoofer outputs are full range, it will be necessary to adjust the crossover frequency to your requirements on the subwoofer’s control panel. Consult the subwoofer instructions or consult your dealer for additional information.
When using a single subwoofer and a separate mono power amplifier the PT2500 subwoofer outputs must be com- bined using an optional “Y” adapter. If there is no crossover in the subwoofer an optional, external low pass filter or crossover system must also be used.
When using the PT2500 with an external
5.1digital audio decoder such as the Harman Kardon ADP303, connect all
Channel Outputs abcto the decoder’s inputs. Use an optional “Y” adapter to combine the subwoofer out- puts and connect the “Y” adapter to the decoder’s subwoofer input. The outputs of the digital audio decoder should then be connected to your power amplifiers.
Speaker Selection and Placement Depending on the type of center channel speaker in use and your viewing device, place the center speaker directly above or below your TV .
Depending on the specifics of your room acoustics and the type of speakers in use, imaging may be improved by moving the front left and right speakers slightly for- ward of the center channel speaker. If possible, adjust all front loudspeakers so that they are aimed at ear height when you are seated in the listening position.
Using these guidelines, you may find that it takes some experimentation to find the correct location for the front speakers in your particular installation. Don’t be afraid to move things around until the system sounds correct. Optimize speaker locations so that pans across the front of the room sound smooth, and that sounds from all speakers appear to arrive at the listening position at the same time with- out delay from the center speaker as opposed to the left and right speakers.
Surround speakers should be placed on the side walls of the room, at or slightly behind the listening position. The center of the speaker should face into the room with the speaker drivers pointing towards the front and rear of the room. The speakers should be located so that the bottom of the cabinet is at least 24″ higher than the listeners’ ears when in the desired area.

The distance between the left and right speakers should be equal to the distance from the seating position to the viewing screen. You may also experiment with placing the left and right speakers slightly forward of the center speaker.
