Installing Your Surround Speakers; Wall Mounting - Acoustic Research HD510 Manuel D'installation Et D'opération

Installing your Surround Speakers

The surround speakers are identical and can be used for any channel.
Surround Speaker Placement
Speaker placement is critical, and can make the difference between good and great
sound quality. For optimum sound quality, position your front (main) surround speak-
ers slightly in front of the video screen and turn them slightly inward (towards the cen-
ter of the listening area). This reduces the possibility of reflection from the video
screen or side walls. Turning the surround speakers farther inward produces a smaller
sound stage and focuses the sound more directly to the listener's ear. Turning them less
or not at all produces a larger sound stage and compromises localization of the sounds.
Placing the left and right surround speakers closer to the front wall, side walls, or cor-
ners will increase the amount of audible bass. The HD510 surround speakers are de-
signed to be placed within 18 inches of a wall for optimum tonal balance. Rear
speakers should be placed approx at ear level or slightly higher. The center channel
speaker should be placed above or below the television. Based on your listening pref-
erences, you will want to experiment with the placement of your surround speakers.
When possible, the surround speakers should be installed at the same level as the lis-
tener's ears. See "Surround System Configuration" on page 5 for more information on
speaker placement.
Connecting the Surround Speakers
Strip approximately 3/8" of the insulation from the speaker wire, exposing the bare
conductors. Twist each end of the speaker wire, and then connect the speakers in phase.
Connect the positive (+) terminal from the Receiver to the positive (+) terminal on the
speaker. Red typically indicates positive. Connect the negative (-) terminal from the
Receiver to the negative (-) terminal on the speaker. Black is typically the color code
for negative.

Wall Mounting

There are 2 mounting methods for the HD510 surround speakers. The first is using the
¼-20 threaded insert located on the back of the speaker. This is designed for use with
after-market mounting hardware. See your local dealer for details. Another option is to
use the "J" shaped wall brackets included with the system. Determine the placement
for the speaker and mount the wall brackets securely to the wall. NOTE: Choose the
appropriate mounting fasteners (not included) for your wall to ensure a secure and sta-
ble installation.
NOTE: The rubber bump-ons can be used when the speakers will sit on a shelf.
These bump-ons will raise the speaker slightly, allowing it to sit level when the
wire management channel on the back of the speakers is used.
