C. Unpacking.
After unpacking the Model AM30, 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 immedi-
ately 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 Connections.
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 white wire with the red indicator and the negative (-)
audio line to the white wire.
WARNING
This speaker is an 8-ohm device and should not be connected to a 25 VRMS or a 70 VRMS line
without the use of a step-down transformer. Failure to follow these instructions may result
in property damage, serious injury, or death to you or others.
