SECTION 2 - SYSTEM INSTALLATION

NOTES

SP E AKE R PLACE ME NT RULE S

It is vitally important that any speakers mounted above the floor be properly secured! Safety must come first. Never place speakers on a shelf without an approved retaining mechanism. Never screw eye-loops or other hardware directly into speaker cabinets. Unsecured or improperly secured speakers represent a safety hazard which can result in serious injury.

The installation of any home theater system represents a balancing of aesthetic and functional requirements which frequently are at odds with each other. The following information should be used to optimize the placement of the speakers and achieve the best results while still conforming to the architectural limitations inherent in the installation.

C E N T E R MA I N

1. If the speaker is behind a perforated screen, place it as far forward as possible, nearly touching the screen.

2. If it is above or below the screen, it must be placed as close as possible to the edge of the screen, along the same plane as the screen.

3. If it is on a shelf, in a pre-fabricated hole in the wall or in a cabinet opening, place it as far forward as possible.

3.1. Any gap around the speaker must be filled. If the gap is ½" closed-cell foam can be used. For gaps greater than ½" it is recommended that you "frame" the speaker with ≈¾" MDF, plywood or other solid panel material.

4. Do not allow anything to obstruct the baffle area of the speakers.

4.1. If decorative cloth is placed in front of the speakers, be sure the frame for the cloth does not obstruct the front of the speaker.

L E F T A N D R I G H T MA I N S

1. If the speaker is on a shelf, in a pre-fabricated hole in the wall or in a cabinet opening, place it as far forward as possible.

1.1. Any gap around the speaker must be filled. If the gap is ½" closed-cell foam can be used. For gaps greater than ½" it is recommended that you "frame" the speaker with ≈¾" MDF, plywood or other solid panel material.

2. Do not allow anything to obstruct the baffle area of the speakers.

2.1. If decorative cloth is placed in front of the speakers, be sure the frame for the cloth does not obstruct the front of the speaker.

S U B W O O F E R S

1. In nearly all cases, the best location for subwoofers is on the floor, in the front corners of the room. Place them with the woofers facing the listening area.

1.1. If the subwoofers cannot be placed in the corners, the next best position is on the floor, against the front wall. In this instance, better low frequency coupling may be achieved by turning the subwoofers sideways such that the drivers and ports are next to the front wall.

2. If the subwoofers are placed in a pre-fabricated hole in the wall or in a cabinet opening, place them as far forward (toward the opening) as possible.

2.1. Any gap around the subwoofer must be filled. If the gap is ½" closed-cell foam can be used. For gaps greater than ½" it is recommended that you "frame" the speaker with ≈¾" MDF, plywood or other solid panel material.

2.2. Do not allow anything to obstruct the driver or ports of any speakers.

2.3. If decorative cloth is placed in front of the speakers, be sure the frame for the cloth does not obstruct the driver or ports of the subwoofers.

S U R R O U N D S P E A K E R S

Wall Mount

1. Side surround speakers are to be mounted vertically and placed directly at the sides of the listening area.

2. Rear surround speakers are to be mounted vertically and placed on the rear wall of the listening area.

3. The bottom edge of all surround speakers must be at least 24" above ear level. 3.1. Avoid elevating surround speakers more than 48" above ear level.

4. If the speaker is on a shelf, minimize the width and depth of the shelf as much as possible. 4.1. Place them against the wall.

5. If they are placed in a pre-fabricated hole in the wall or cabinet opening, it must exceed the speaker width by no less than 24".

5.1. Center the speaker in the opening.

5.2. Any open area behind the speaker must be filled to minimize acoustic resonances.

6. Do not allow anything to obstruct the drivers.

6.1. If decorative cloth is placed in front of the speakers, be sure the frame for the cloth does not obstruct the drivers.

Ceiling Mount

TAKE NO CHANCES!

The mounting hardware provided with Synthesis surround speakers IS NOT suitable for ceiling installation. Improperly suspended speakers represent a serious safety hazard which can result in injury or death.

1. Side surround speakers are to be mounted with the top of the enclosure facing the center of the room, as near to the adjacent wall as possible.

2. Rear surround speakers are to be mounted with the top of the enclosure facing the video display screen, as near to the adjacent wall as possible.

3. If they are placed in a pre-fabricated hole or cutout in the ceiling, it must exceed the speaker width by no less than 24".

3.1. Center the speaker in the opening.

3.2. Any open area behind the speaker must be filled to minimize acoustic resonances.

4. Do not allow anything to obstruct the drivers.

4.1. If decorative cloth is placed in front of the speakers, be sure the frame for the cloth does not obstruct the drivers.

RE S T O RE PROCE S S O R DE F AUL T SE T T I N G S

*This is applicable to all Synthesis models equipped with an SDP-2, SDP-2D or SDP-3 processor.

It is recommended that you restore the Surround Processor to the factory default settings prior to system calibration. This will ensure that you do not waste time later troubleshooting an apparent problem, only to find that the Processor settings were the cause.

1. Use the remote control to turn the processor OFF. 2. Use the remote to turn the processor back ON.

3. Immediately press and hold the MUTE button on the remote control.

4. In a few seconds, the "FACTORY PRESETS MENU" will appear on the Processor's readout. 5. Release the MUTE button.

6. Scroll to and select "RESTORE DEFAULTS".

7. W hen the message "FACTORY DEFAULTS RESTORED" is displayed press DONE to return to normal operation.

Alternatively, you can adjust each setting manually. They should be set as follows:

A. Volume Control: 0dB

B. Speaker Configuration:
