The Brilliance Pack provides authentic emulations of the EMI RS127 and RS135 EQ units, which were built in the early 1960s to supplement the EQ on the legendary REDD mixing consoles. These 'presence boxes' were used on countless seminal recordings at Abbey Road during the '60s, including almost every album by The Beatles.

Three plug-in modules are included: the RS127 Rack is modelled on the original rackmount Brilliance Control and the RS135 recreates the 8kHz boost unit. The RS127 Box plug-in was created by modelling the standalone Brilliance Control with an EMI transformer used to connect it to modern consoles. The plug-in features an exaggerated response or 'transformer effect' at some settings, which is due to an interaction between the RS127 and the transformer.
