SSL X-Rack Dynamics Module

The X-Rack Dynamics Module, XR 618 from Solid State Logic provides a single channel of dynamics for an X-Rack or Mynx enclosure. The unit was designed around the same SuperAnalogue circuitry as used in SSL's XL 9000 K console, and provides compression, limiting, expansion, and gating.

Features:

• Single channel, modular dynamics processor based around SSL's XL 9000 K SuperAnalogue console circuitry
• Comprises a compressor/limiter and a gate/expander, both of which use the same gain element
• "Key" side chain input on the rear panel of the unit allows for external control of the dynamic process
• The side chain control signals of multiple modules can be linked
• When two (or more) Dynamics sections are linked, whichever section has the most gain reduction will control the other section
• Dual five-LED ladders display gate/expander functioning
