"I must tell you that the sound of my AD2044
is spectacular - drop dead quiet, absolutely transparent, and full
frequency response even during heavy squeezing." - Jim B.,
IA
"The
AD2044 does simply amazing things for vocals and bass guitar as
well as across the stereo buss. It can also warm things up if pushed
a bit harder. If you can only own one analog compressor, I don't
think anyone can possibly go wrong choosing this one!" - Bob
S., NY
"The
AD2044 is my favorite for vocals, bass, acoustic piano, and across
the mix buss. It is the most musical and transparent compressor
I have ever heard." - Rob C., CA
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.
