"We have 2 of these available and they are boxed as new. The SSL X-Rack Dynamics Module is based on the channel dynamics unit from the XL 9000 K Series console. The SSL X-Rack Dynamics Module incorporates compression, limiting, expansion and gating with a number of options for hard or soft knee operation and peak, or RMS sensing. All of this circuitry is designed using SSLs acclaimed SuperAnalogue design techniques to deliver fantastic sound quality with very low noise and distortion. The X-Rack is a modular rack system that incorporates a unique Total Recall capability. Featuring the same SuperAnalogue processing as our XL 9000 K series console, the X-Rack now boasts five optional moduless - Four Channel Input, Master Bus, Mic Amp, Channel EQ and the original Dynamics module. This combination now make it possible to configure X-Rack as a stand alone mixer & analogue summing system, or as a stand alone processing solution for studio & live applications or working with the flexible inserts of an AWS 900 to provide a complete SSL channel processing solution for the console.
