Originally launched in late 2011 and updated in 2013 as the Anniversary Edition, it set the standard for 73s in 500 Series format, as it is essentially a reformatted 80 Series one .

Mainly designed as a rackmount 500 Series mixer, it allows 10 tracks to be summed while being processed with 500 series outboard. A passive summing topology employing a class A transformer coupled output stage gives it a classic, vintage 70s sound. It delivers a maximum of 1.6 Amps per rail to the 500 Series modules.

 Some of our designs have evolved to upgraded versions, but we are so proud of them, that we think they deserve a special place to hang for posterity.
