Connecting speaker wires
Loosen speaker terminals by turning counter clockwise. Strip ½”/12 mm in-sulation 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 posi-
tive (+) 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 com-mercial installations
with many speakers and requires an amplifier with matching transformer outputs. A switch
located next to the terminals al-lows 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.
In-stall the covers (k) over the thumb screws. The curved bracket can be
ad-justed in the wall bracket by loosening the two ½” allen bolts (e) and
re-tighten 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.
