The Australian Monitor Installation Series AMC line of amplifiers
takes the heritage & reliability of our famous AMIS series &
integrates these features into a low cost amplifier format for
applications where reliability is everything, but the more elaborate
features of our AMIS series are not required. The 120 watt
version of the AMC series is a 2 RU mixer amplifier featuring 70
volt line (100v 230/240V version) & 4 ohm outputs & 3 universal
mic/line inputs.
Master volume & overall treble/bass controls are provided, along
with Voice triggered muting (defeatable) giving channel 1 priority
over inputs 2 & 3. There is also facility to internally add & a tone
generator card. Protection includes short circuit and thermal
detection and shut-down.
The Australian Monitor AMC series give the contractor a low cost
alternative in applications that are cost sensitive, but still require a
high quality of sound reproduction & reliability.
