The 6386 and ES-8 are modern two channel limiters designed to have the compression characteristics of a vintage unit, but with a higher level of sonic accuracy.
Classic feedback compression based on the Fairchild 660 and 670
The 6386 uses the same gain control tube (remote cutoff triode) as the Fairchild 660 and 670.
The ES-8 uses a more readily available (and less expensive) tube
with the same compression characteristics as the 6386.
Modern class A, solid-state gain make-up stage for wide bandwidth and low distortion
Soft-knee design with smooth transition from compression to limiting
Fast attack (0.5ms) and release times ideal for tight program compression or tracking
Low noise and superior transient response
Three sidechain operating modes: Fast, Presets and Manual
Two completely independent channels with stereo linking
Tubes calibrated for precise stereo balance
Hard bypass switches for each channel
Sidechain inserts for frequency-dependent compression and de-essing
Transformerless balanced output stage capable of delivering +27dBu
Soft-start warm-up with outputs bypassed until all voltages are stabilized
Gold-plated relay contacts, I/O connectors and tube sockets
Fully regulated high voltage (250V), filament and bipolar power supplies
Custom toroidal power transformer with shield for minimum hum
Polypropylene capacitors and metal film resistors
Limited production, hand-built product
