FIRST THINGS FIRST

CONNECTING, PLACING & BALANCING THE SPEAKERS

CONNECTING THE WIRES

Each speaker - the two main, two surround and one central - has a designated set of terminals on the back panel of the central unit.

Uncoil the speaker wires and locate the bare ends. Press and hold down on the tab to open the red terminal, then insert the red (+) wire. Release hold to close tab. Use the same procedure for black (-) wire into black terminal.

WARNING: Be sure to follow these instructions carefully. The system can be damaged if speakers are improperly connected.

SETTING UP FOR SURROUND SOUND

THE MAIN SPEAKERS

The two main speakers should be set between six and 10 feet apart. Putting the speakers any closer or any farther apart may result in distorted sound.

The speakers should also form a 45 degree angle to the central listening point in the room, creating a triangle of listening enjoyment.

NOTE: You may need to place the main speakers closer together when not utilizing the center speaker. Do not place them so close, however, that their magnetic fields affect the TV’s reception.

THE CENTER SPEAKER

For optimal performance, you should try to place the center speaker as close as possible to the same height as the left and right main speakers. You should also try to align all three speakers, or set the center speaker slightly behind the left and right mains. However, you should never place the center speaker forward of the left and right mains, as this will distort the sound for those listeners not seated in the center of the room.

THE SURROUND SPEAKERS

Placement of the surround speakers for optimal performance is truly subject to the size and type of room in which the system is to be placed.
