AUSTRALIAN MONITOR AM1600 User manual

lntroduction
he o dest continent in the wor d and the last of the
true pioneerinq countries, Australia is without doubt
the most arduous, toughest testing ground in the world
for any sophisticated 'state of the art'electro-mechanical
equipment. With a heritage as tough as it gets Australian
Monitor has developed a powerful range of arnplifiers to
survive not only the severity of the 'Diese and Dust'
touring environment, but also to provide the'Reference
Standard' of transparent sonic integrity demanded by the
industry's foremost international audio recording studios.

sERIES amplifiers incorporate latest generation high speed
latera Meta Oxide Silicon Field Effect Transistors
providing high slew rate fast rise time, wide band flat
frequency response, super low noise, THD and lMD. The AM
SERIES is a pure example of Australian Monitor's design
phi osophy. Quality without compromise, the combination of
solid mechanical construction, high perforrnance electronics
and com prehensive functionality.

hand crafted to a standard of excellence superior to that
found in simi ar products from elsewhere in the world.
Australian Monitor is built to last, utilising the latest in
CAD/CAM techniques and aerospace materials, the 6mm
a uminium a loy panels and custom al oy extrusions are
precision sawn and rni led to form a modu ar chassis and
construction that is second to none. Symmetrical layout, even
weight distribution and multi point mounting of the a loy
panels, moduies and hardened steel pan provide a perfectly
rigid monocoque chassis, minimising the effects of fatigue
and extreme abuse that can be experienced by international
concert touring systems.
Protection Network
I n the design of ine AM SERIES the utrost importdr(e was
lplaceo on prole(lio1. Lavour, g.6u66 6t, decoupl.rg and
componentry have all been optimized to provide stability,
reliability, and of course longevity. The eight po;nt maximum
protection network consists ofi Mains circuit breaker,
lndependent rear panel t power rai fuses, lnput muting at
turn on, Short circuit protection with LED indication, lnput
over voltage protection, R.F. interference suppression,
Thermal overload protection with LED indication, Main5
inrush current suppression and LED indication.

Cooling System
f a<h <ha--el of ar AM-5tR t5 amplilie is i-d'vidually
Lcoolecr by a dual speed axiai tan olowing a r dire(Lly over
critical drive and PSU components. Fresh cool air is drawn
through the front vents passed across a highly efficient heat
excha nger and exha usted from the rear of the u nit. Each heat
exchange module has a perimeter of 1.5M (59') and has a
total surface area of over 880,000 sq mm (1,360 sq ins). The
efficiency of the cooling system maintains a thermally safe
environment even under the most extrerne and adverse of
cond itions

used in a variety of situations and in either 2, 3 or 4 channe
configurations: 1) four individual mono channels, 2) tri-
amped with one channel pair bridged,3) as a stereo unit wjth
two pairs of channels bridged. All of the four amplif ier stages
use c osely matched, stable, high speed lateral Metal Oxide
5ilicon Field Effect Transistors. Rear panel bridge switching is
supplied as standard with front panel indication.

I more a-d t^e powe ng of mu tip e loudspedkers, tna Jse
of 70 or 100 volt lines s recommended. There are several
benefits to this method including the reduction of osses due
to cable resistance, the reduction in changes to the
loudspeaker response due to cable reristance, and the ability
to use multiple's of loudspeakers with individual level
adjustment, a I o{ which can be run in paraliel without any
u ndue load inq effects to the arnplifier.
The AM2100 is a specifically designed and dedicated, bridged
monobloc am plifier for h ig h power 100 vo t line applications.
The AM2100 will produce 100 volts of current into a line
impedance of 4 ohms, generating 2500 watts of power
without the need for ancillary ine transformers. The front
panel features a buffered 21 position detented attenuator. A
comprehensive LED metering section indicating:- the signal
output in -3dB increments from -27d8 to clip point, trailfuse
continuity, channel fuse continuity, and faulvthermal status.
The mono single channel input is via XLR connector and the
100 volt line output is by bind ing posts.

optionalstudio version has bridge switching as standard with
special rear mount fans, alternatively the AM1600 can be
bridged via cables. The AM 1600 has a n extrennely well proven
track record as an audio standard in world class ultra critical
studio monitoring. Australian Monitor anrplifiers can be
found in some of the worlds finest and most prestigious
music productions studios such as The Record plant, Los
Angeles, EMI 301, Sydney. Sound lnterchange, Toronto. Sony
CD Mastering, Sydney and many many rnore.
