SONANCE SM55 & SM55SST SURFACE-MOUNT SPEAKER

•The Mounting Plate allows the speaker to be installed after the ceiling has been finished. The Mounting Plate also allows the speaker to be rotated after installation to align it with design elements in room.

3.If there is no J-box in the ceiling, the speaker can be mounted directly on the ceiling surface, without using the Mounting Plate.

•If the speaker is installed without the Mounting Plate it cannot be rotated after installation.

Installation Using a J-Box

1.Run speaker wires through the ceiling or conduit, from the amplifier into the J-Box. Mark the wire’s “+” and “–” leads.

•Consult local building codes before running speaker wires through ceilings.

2.Bring the speaker wires through the J-Box and attach them to the binding posts on the back of the Mounting Plate. (The SM55 plate has one set of posts; the SM55SST plate has two sets, see Figure 4.) The binding posts will accept single banana plugs or bare wire.

•Loosen the set screw on the binding post, insert the plug or wire, then tighten the set screw to secure the wire.

IMPORTANT: When using bare wire, be sure that no stray “+” and “–” strands touch each other. (Stray strands that

touch each other can cause a short- circuit that can damage the ampli- fier.)

3.Use the 1½” x 6-32 flat head screws included

with the Mounting Plate to attach it to the J-Box. (See Figure 5.)

• Use two screws for a single-gang J-Box; use four screws for a double-gang J-Box.

painted after the Plate is installed. Remove the paint plug before installing the speaker.

5.To install the speaker, place the speaker against the Mounting Plate so that the male terminal connectors on the speaker fit into the female connectors on the Mounting Plate. The neodymium magnets on the speaker will secure the speaker to the Mounting Plate. (See Figure 6.)

Be sure to align the “+” and “–” connectors on the speaker with the corresponding connectors on the Mounting Plate.

•After the speaker is installed you can rotate it to align it with design elements in the room. See Speaker Adjustments: Rotating the Speaker, on page 3.

Installation Without a J-Box

1.Remove the grilles from the speakers.

•The grilles are held on the speakers by 2 small tabs on each side of the grille frame. Use a flat-blade screwdriver to gently pry each side of the grille frame away from the speaker to release the tabs, and slide the grille off the speaker (see Figure 7).
