Connecting the Subwoofer

IMPORTANT: To avoid damaging your equipment, make sure the subwoofer and all components are turned off before making any connections.

Subwoofer Placement

Placement of your subwoofer will dramatically affect its performance. Your AR sub- woofer is designed to work best when placed on the floor within 15 feet of your front speakers. For detailed accurate bass response, place your subwoofer near a wall, but away from a corner. If you prefer fuller, more accentuated bass, try placing your sub- woofer directly in a corner. This will substantially increase bass response. When pos- sible, place the subwoofer close to your system's front speakers to keep wire or cable runs short. See “Surround System Configuration” on page 5 for more information on speaker placement.

Since low frequency sound is omni-directional, the subwoofer can be placed anywhere in the room. Use the Low Pass Frequency control and the Phase switch to adjust the output. Use the subwoofer's Level control to adjust the volume relative to the place- ment (this may require resetting the subwoofer's polarity switch). See “Subwoofer/ Preamp Controls & Connections” on page 7 for details on adjusting these settings.

Connecting the Subwoofer Line-In

Connect an audio cable from the Subwoofer output on your receiver to the Line-In in- puts on the subwoofer. Note that the subwoofer has a left and right input, allowing it to receive stereo bass signals. If your receiver has only one output, you can run a single audio cable into either the left or right input on the subwoofer. Another option is to use a “Y” cable to connect both the left and right inputs on the subwoofer.

Connecting the Speaker Level (High Level) Inputs

For older receivers with no LFE or Subwoofer outputs, run speaker wire from your re- ceiver's front left and right speaker level outputs to the left and right speaker level in- puts on the subwoofer. Connect the front left and right surround speakers in parallel with the subwoofer.

NOTE: To avoid possible output problems, do NOT use the "speakers B" out- put to attach the subwoofer to a receiver.

IMPORTANT: All speakers in a system must be connected with the same po- larity. Polarity is indicated by a color stripe on the insulation, by ridges mold- ed into the insulation, or by the colors of the wire - one copper and one silver. Strip the insulation from the speaker wire ends to reveal the bare conductors before connecting to a speaker, subwoofer or receiver. Always connect the red

(+)terminal on the receiver to the red (+) terminal on the Subwoofer, and con- nect the black (-) terminal on the receiver to the black (-) terminal on the Sub- woofer. The same is true for hooking up the Receiver outputs to the Front speakers: red (+) to red and black (-) to black.
