A More Thorough Examination...
The Australian Monitor Installation Series AMIS480P is a robust, highly featured 4 channel booster amplifier.
Offering 4 independent channels each delivering 80
watts into 4 ohms or 70/100 volt line, the AMIS480P
is designed to operate in extreme conditions to give
the contractor the most reliable 4 channel amplifier
available today.
Engineered with maximum attention to channel
isolation, with individual ground lift switches and
level control for each channel the AMIS480P will
operate as 4 individual amplifiers in a rack space
friendly 2RU chassis.
For ease of installation each channel input can be
routed to the next channel via the rear panel link
switches, eliminating the need for daisy chaining
or Y-split cables. The AMIS480P also offers signal
present and clip LED indicators for each channel as
well as a thermal protect indicator.
The AMIS480P is the perfect partner four many of
Australian Monitor’s zone solution products like
