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

• 

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 retrofi t 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.

If a situation should arise which cannot be resolved 
through the information contained in these installation 
instructions or notes, please contact SOUND ADVANCE

• 

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.

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 amplifi er. 

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.

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 amplifi er to the speaker.
