INTRODUCTION
The ZAM-180 is a CAN data bus module that contains two speaker zones and
one audio amplifier, capable of operating at 25(150W), 70(180W) or
100(165W) VRMS. The two speaker zones can be wired and operate as either
a single Class A zone or a single Class
B zone or as two Class B zones
independently protected to provide
split zone or interleaved speaker
zones.
The ZAM-180 can also be used as a
backup amplifier to serve as a backup
for other ZAM-180 amplifiers in a 1 to
1 backup or 1 to many backup.
The ZAM-180 also contains a local
external audio input circuit (0 dB) and
a dry contact input to switch on the
amplifier and activate the zones as
configured via the Zeus tool. The
ZAM-180 is capable of amplifying any
one of the 8 audio channels that are
transmitted from the DAC-NET
(Digital Audio Card) via the internal
digital Audio bus ASI (Audio Serial
Interface).
The ZAM-180 mounts at the back of
the enclosure of the FireFinder-
XLS system and occupies ¼ of the
total space of the Mounting Plate
CAB-MP.
