Specifications
The new limiter module, designated
LIM l,
is now available
to
suit Australian
Monitor K-
Series and Opal series
power amplifiers. The module fits within
the
amplifier
case,
and is
compatible
with
all existing
/
new K-series
and
Opal
series
amplifiers. Installation is
as
simple
as
removing the amplifier lid, removing
a
jumper link
and
plugging in the card. The card
is
primarily
intended
to prevent clipping
and
limit power delivery.
Applications include the improvement ofsound quality by the prevention ofclipping, which
also prolongs the life of H.F Drivers
increasing average
power delivery without degrading
sound. The card reduces average power delivery in noise-sensitive venues improving
speech
intelligibility.
As
with
all Australian
Monitor electronics, performance and reliability and guarantied. Only
the highest quality components are used - Roederstein resistors, WIMA
and Roederstein
capacitors,
fully
enclosed cermet
trimpots and high slew-rate,
low
noise,
low distortion
op-
amps. Each module is
individually
tested
to
meet
a
rigorous specification. And, like our
amplifiers, they
are
built to work in
any environment, and
built to
last.

A wide range ofadjustment on attack
and release
times allows the module
to
be used
as
either
a
peak
limiter (short attack, short
release)
to prevent clipping on transients, or
as
an rrns
limiter (long
attack, long release) to control average power delivery and compress dynamic range. This can
be
particularly useful in
speech-only applications where maximum
intelligibility
is needed
with limiter
power.
The gain-control element is highly linear,
has no
efect
on the circuit before
limiting
starts, and
produces no audible distortion while limiting. The signal-to-noise ratio of the amplifiers virtually
unaffected
with
the limiter in circuit,
and
the dynamic range is effectively increased by 16dB.
