The Avalon AD2044 Dual Mono-Stereo, Pure Class A
Opto-Compressor. For vocals, bass, acoustic piano, and across the
mix bus, it is one of the most musical and transparent compressors
available today.
The Avalon 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.
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.
