Bracket.
The brackets comes pre-assembled. If disassembling the bracket for painting, re-assemble it as follow: Place the curved bracket (a) between the wall
bracket (b) and wall bracket cover (c) as shown in fig. 1. Insert two 1” allen
bolts (d) through wall bracket into wall bracket cover and tighten with the
supplied allen wrench. Insert two ½” allen bolts (e) into each side of wall
bracket and tighten towards curved bracket.
Mounting of bracket.
The bracket can be mounted for horizontal or vertical placement of the
speaker. Mount the bracket with four screws (not included) appropriate for
the surface the bracket is mounted to (wood, brick, concrete or other). Take
into account the weight of the speaker (specifications on back). A hole (f) in
the middle of the bracket allows for running the speaker wire through the
bracket if so desired. Cover the screws with four screw plugs (g) fig. 2.
Mounting of port plugs.
If the front of the speaker is exposed to rain directly entering the bass reflex
ports (under the grill), the ports should be closed to avoid filling the
speaker with water. High moisture is not a problem. Remove the grill (h)
from the speaker and insert two port plugs (i) into the bass ports. Re-install
the grill. The speaker will reproduce less bass with the ports closed.

Connecting speaker wires.
Loosen speaker terminals by turning counter clockwise. Strip ½”/12 mm insulation off each wire. Twist strands on each wire to form “solid” wire. Insert
one wire into each terminal and tighten terminal by turning clockwise.
Make sure positive (+) is to red terminal and negative (-) to black terminal
for correct phasing.
Adjustment of I/O 3T.
This model is for 70V or 100V line installation. This is mainly used in commercial installations with many speakers and requires an amplifier with
matching transformer outputs. A switch located next to the terminals allows for adjustments of the level of the speaker in 10W, 5W, 2.5W and
1.25W settings. Adjust the switch to the desired level on each speaker.
Mounting of speaker.
Place the speaker inside the curved bracket as shown in fig. 2 and insert
thumb screws (j) through each end of the curved bracket into the speaker.
Adjust the speaker to the desired angle and tighten the thumb screws. Install the covers (k) over the thumb screws. The curved bracket can be adjusted in the wall bracket by loosening the two ½” allen bolts (e) and retighten them after adjustment.

Painting.
The speaker and bracket can be painted. Spray painting is recommended.
Paint all parts before assembling. Remove the grill from the speaker before
painting and cover the front baffle (l) of the speaker. Apply many thin coats
instead of a few thick coats to avoid the paint running or clogging the grill
holes. Re-install grill after painting.
