STEP 1 -
For easier installation, remove the flange (base) from the
speaker by unscrewing the wing nut while at the same time pressing
inwardly on the wing nut. Place the flange flush with the mounting
surface and mark the location of the three holes with either a marker
or punch (see Figure 1). It is important that the three holes be exactly
aligned with the flange, otherwise you might stress the base or make
the connection unsteady. Insert 3 wall anchors - see diagrams on
back for drilling instructions and use of anchors. (Use appropriate
hardware for your specific mounting surface.)
NOTE: Speaker may also be strap-mounted through the slot in flange
(base) using standard 1/2-inch industrial strapping (not included).
STEP 2 -
After mounting the flange, reattach the speaker to the
flange and aim the speaker for the desired coverage. A 45
o
down-
ward angle is recommended, but this may vary depending upon
speaker layout. Unless otherwise indicated, do not aim speakers
directly at each other or poor paging intelligibility may occur.
STEP 3 -
Remove the plastic cover to make the electrical connection
and set the tap set control (see Figure 2).
Note:
Use 22 AWG shielded,
twisted pair on all wire runs.
Connect speaker wire shield to the
ground (GND) terminal of the amplifierʼs output. Carry the ground
through all speaker cables by tying the shields of the speaker cables
together in a “daisy chain” fashion.
Do not connect the shield to the
speaker itself.
The shield is only connected at the amplifier end and
simply floats.
Connect wires as listed below:

NOTE: The speaker will also work perfectly well with these connec-
tions reversed. However, reduced low frequency response may result.
STEP 4 -
Adjust the tap set control to the desired setting. See table
at right for tap settings and sound pressure levels for the different
horn loudspeakers. Replace the plastic protective cover back over
the exposed area.
NOTE: The two furthermost clockwise settings on the volume control
will produce the same volume.
