SSL X-Rack 4000 E Series Dynamics Module

The new E Series Dynamics Module for 500 Series racks reproduces the legendary sonic signature of an early 80's classic, the SL 4000 E console channel strip, which was featured on countless 1980's recordings. The E Series Dynamics Module features a compressor/limiter and an expander/gate, both of which return faithfully to the circuitry and key components which define the sound of the original SL 611E Series channel strip.
