Speaker Installation

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 chisel. 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
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 con-
nection and set the tap set control (see Figure 2). Note: Use 22
AWG shielded, twisted pair on all wire runs. Com Code: 401882956.
Pec Code: 2734-SPK. Connect speaker wire shield to the ground
(GND) terminal of the amplifier's 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 connections
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.
