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 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.

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 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.
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 amplifi er to the speaker.
