AD2044:
Dual Mono-Stereo, Pure Class A Opto-Compressor |
|

|
|
The
AD2044 features 100% discrete, pure class A signal amplifier
configured with high speed current monitored optical control
elements. These "invisible" opto elements enable the AD2044
to deliver totally transparent, low noise gain reduction within
the minimalist signal path design. No VCAs are incorporated.
Variable attack and release controls plus side chain access,
provide unlimited creative control from soft compression to
hard limiting.

SONIC EXCELLENCE
The Avalon AD2044 Pure
Class A opto-compressor is the most transparent, low noise
optical-compressor available today. Designed to optimize absolute
signal integrity and musical performance, the AD2044 combines
advanced electronics with sonic excellence unequaled by lesser
designs. The AD2044 is the perfect solution for two buss music-program
compression, mono bass and instruments and mastering applications.
Features
include state-of-the-art, balanced 100% discrete, Pure Class
A signal amplifiers, practical "real-world" user features
and rugged hardware designed to deliver true high performance
audio for many years.
LINEAR OPTICAL COMPRESSION
Custom manufactured, high speed linear opto elements provide
the non invasive passive attenuator system for invisible gain
reduction. The AD2044 incorporates a unique external control
loop and current monitored optical driver for smooth control
plus the benefits of traditional vintage LDR compression.
MINIMUM SIGNAL PATH
DESIGN
Avalon's advanced true symmetry design offers high-voltage,
large headroom, extended bandwidth and very low noise. The
use of 100% discrete, Pure Class A signal amplifiers offer
the serious music professional unlimited sonic character and
a natural harmonic detail that enhances the program material
and becomes one with the music itself.
The
AD2044 can be found in the world's leading recording studio's,
mastering facilities and artist/producers outboard racks.
These professionals rely on the AD2044 daily to help them
complete their "sonic signature" and turn recordings into
musical masterpieces.
