Modular Rackmount Design

By offering the XRack Dynamics Module in a convenient, vertical rackmount design, SSL is offering an opportunity to piece together a mixed-and-matched setup combining any number (up to eight per XRack) of classic SSL mic pres, EQs, or Dynamics Modules. This allows you to build your ideal setup. If you want three pres, an EQ, and four Dynamics Modules, you can. If you prefer more EQ options than Dyanmics Modules, you can build it. Or if you'd like to have a 4-channel SSL front end with two classic EQs and two Dynamics Modules for post-recording tweaks, you can have that as well. With the XRack's modular design, you can customize the setup to suit your working style, which is quite an innovation - not to mention that all components that work with the XRack boast the legendary SSL sound.

Total Recall

The truly amazing thing about the XRack Dynamics Module (as well as the pres and EQ) is that the XRack integrates Total Recall - an absolute first in analog equipment. Total Recall allows you to set any or all of the modules in the XRack, dial in your perfect sound, and then save the preset to one of the 32 flash memory locations. Saving presets was once territory only traversed by digital outboard gear and plug-ins, but the XRack from SSL gives you the classic SSL analog sound with the convenience of digital. Once you've built your perfect SSL setup in the XRack and found your ideal sound, save the settings for the next time you need that awesome compression or EQ you used on the last session.

Holds up to Eight X-Rack Modules

The X-Rack Empty is designed to hold as many as eight X-Rack modules.
