POWERAMPLIFIERS
Australian opals are among
the most
beautiful
and
sought-after iridescent gems in the world. Of all
the
known precious stones,
only opal can
show
the
complete
range
of
spectral hues in a
glorious
balance.
The Australian
Monitor
Opal Series is a gem
among
amplifiers,
the
culmination
of
countless hours
of
dedicated
research and development.
Without sacrificing Australian Monitor's
legendary
quality
or
design, the new affordable Opal
Series
response combined with
a
high slew rate, and
high
damping
factor
for
accurate loudspeaker driver control.
Construction
Built
to
the
highest standards
the
Opal
Series
utilises
a
2
unit high, module monocoque
chassis.
Its
symmetrical construction features heavy
gauge
aluminium front and rear panels integrated with
a
rigid
folded
steel pan and steel side bracing.
brings within everyone's reach superlative
sonic
performance,
unmatched dynamics and
of
course our
renowned "all terrain" construction techniques.
Audio Reproduction
The Australian
Monitor
design team have drawn
on
a wealth of experience in sophisticated audio
circuit
designs for CD
mastering
facilities, music
recording
studios
and
other esoteric audio
monitoring
situations. ln
the new Opal Series
they
have created
one of the finest high definition audio signal
paths
available, exhibiting dazzling transients,
timbral
accuracy
and outstanding
sonic
integrity.
The
MOSFET-based
circuit design with
double-
balanced current-mirror drive circuit provides
wide
bandwith, ultra low THD
/
lMD, super fast transient
Cooling
Fourcustom
aluminium
alloy
heatsinks, providing
a6.0
metre perimeter with over 500,000 square mm
of
convection
cooling area. lnternal airflow
is
assisted by
a
signal-dependent, silent
axial fan, providing
"on
demand"
cooling.
Power Supply
At
the heart
of
the
Opal
2802
is
a
high
efficiency 800VA
toroidial
mains transformer, the current source
for
two
massive
15,000 microfarad computer
grade
reservoir
capacitors. While
maintaining high
power
output, this
topology minimises ELF emissions
to
ensure your
safety.
