C. Unpacking.
After unpacking the Model AM30T, examine it for damage that may have occurred in transit.
If฀the฀equipment฀has฀been฀damaged,฀do฀not฀attempt฀to฀install฀or฀operate฀it.฀File฀a฀claim฀
immediately with the carrier stating the extent of the damage. Carefully check all envelopes,
shipping labels and tags before removing or destroying them.
D. Mounting.
CAUTION
The selection of the mounting location for the device, its controls and the routing of the wiring is to
be accomplished under the direction of the facilities and the safety engineer.
The speaker is intended to be mounted on any relatively flat and rigid surface. Hardware for
mounting the speaker to the surface is left up to the installer.
Mounting to wall, ceiling, or to electrical boxes is accomplished without the need of adding a
steel฀plate฀to฀the฀base.฀Bonding฀straps฀may฀be฀used฀for฀mounting฀to฀beams.฀Mounting฀holes฀in฀
the base should be knocked through as needed.
WARNING
This unit is heavy and should be mounted on a rigid surface capable of supporting
the weight of the speaker.
E. Electrical Connexions.
WARNING
Do not connect wires when power is applied.
NOTE
Audio wires should be sized properly by your licensed installation electrician for your service
application.฀This฀cable฀requires฀a฀twisted฀shielded฀pair฀with฀an฀18AWG฀minimum฀and฀should฀
produce no more than 15% signal loss over the length of the cable run.
Connect the positive (+) audio line to the red wire and the negative (-) audio line
to the black wire.
A transformer and power selector switch are installed in the rear housing.
The level of the AM30T may be adjusted by moving the switch setting. Clockwise increases
the power. Since the same switch and transformer are used for either the 100-volt, 70-volt
or 25-volt line, the power setting depends upon the amplifier output that is used, 100-volt, 70-
volt or 25-volt.
