AVALON DESIGN AD 2044 - 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.
