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.
