This is our state of the art Tube
Compressor. After years of painstaking development, Signal
Audio Workshop is proud to introduce the Gainrider. An all
tube, Class-A, Dynamic Range Controller, Stereo Limiter
Inspired by the early tube compressor topologies like the
Fairchild 670 Tube Compressor (valued at $30,000) we decided
to embrace the variable bias topology as our signal path
with pure tubes and transformers circuitry and no solid
state components in the signal path. We combined these early
giant compressors signal path topology with a new, up to
date control mechanism for the side chain.
Our side chain psyco-acoustic approach features conventional
Attack and Release functions working alongside intelligent
Crest Detectors that respond to complex music signals and
not just the global levels, riding fine nuances in music
like our ears do.
The M.S (Mid Side Compression) is an extra feature that
encodes stereo information to separately treat the center
and sides information of a stereo signal.
The Gainrider tube compressor is handcrafted with unprecedented
attention to detail both internally and externally. The
compressor features an embedded black panel with shimmering
internal lettering and smooth gain reduction display.
