inserted, and that the spring receptables are the fl at, slotted type.

PRODUCT-SPECIFIC NOTES

•The UMB8-10 Universal Mounting Bracket has horseshoe tabs that allow it and the PBB8-10 backcan to be mechani- cally interlocked. Please refer to the instructions provided with the UMB8-10.

•SOUND ADVANCE does not recommend installing a CT10 loudspeaker in walls and fascias. The springs may be subject to uneven compression, which can result in speaker displacement.

•Backcans and plaster rings with U-shaped torsion spring receptacles are NOT compatible with SOUND ADVANCE products. Make sure the torsion spring receptacles of the selected hardware (if other than the UMB8-10) are the fl at, slotted type (i.e. Atlas Sound T-95 Series backcans and T-75 plaster rings).

•In hard-to-access plenums or retrofit installations requir- ing backcans, CT10 loudspeakers can be installed using a blind-mount enclosure (Atlas Sound BMT95-8 Series or similar). These enclosures have mounting facilities for spring-mount speaker models. Please refer to the manufacturer’s specifi cations for more information.

LOUDSPEAKER CONNECTION:

GENERAL NOTES:

•Always allow suffi cient slack for attachment to the transformer tap pigtails or other connection points as required.

•Take care not to cut the insulation or otherwise damage the wiring when tightening the cable clamp.

•Avoid dripping solder onto any portion of the loud- speaker.

70.7V/100V INSTALLATION

1.Connect the black pigtail wire from the transformer primary to the ground (common, or ‘–’) lead from the amplifi er.

2.Choose the appropriate transformer power wire (see chart at top of next column) and attach it to the ‘+’ lead from the amplifier.

NOTE: Do not use the white trans- former wire in a 100V installation.

3.Secure the connections using a suitable method such as wire nuts, crimps, or solder/shrink tubing as

required by local codes.

• Fold-over and securely tape any unused transformer power wires making sure that the bare leads do not touch each other or the speaker backcan assembly. Insure that all wiring does not touch the loudspeaker surface.

8-OHM INSTALLATION

1.Cut the transformer secondary wires as indicated in the diagram below.

2.Strip ¼” – ½” of insulation from the wires that remain connected to the speaker (not the ones connected to the transformer).

3.Connect the black wire to the common (‘–’) lead from the amplifi er; connect the red wire to the ‘+’ lead from the amplifi er.

4.Secure the connections using a suitable method such as wire nuts, crimps, or solder/shrink tubing as required by local codes.

•Fold-over and securely tape all transformer wires making sure that the bare leads do not touch the connections from the amplifier to the speaker.
