PSP Datamix A567 is a three-band equalizer plugin modeled directly from the original Datamix console modules used at The Record Plant and Electric Lady Studios during the golden age of rock recording. Endorsed by Eddie Kramer, the engineer behind recordings with Jimi Hendrix, Led Zeppelin, and KISS, this plugin captures the particular sonic signature that defined that era's mixing aesthetic.
The EQ architecture comprises a low band with frequency-dependent behavior (peaking on boost, shelving or peaking on cut), a mid band offering both peaking and notch-cut modes, and a high band with similar flexibility. What distinguishes the A567 is its inherent character. Even bypassed, the preamp and output stages (which include transformer emulation) impart a colored sonic signature that prevents truly transparent operation. This is intentional design - the console was never meant to sound neutral.
The plugin employs 64-bit double precision mathematics to maintain accurate filter behavior across the entire frequency spectrum, while FAT (Frequency Aliasing Tuning) automatically engages at sample rates below 50 kHz to prevent aliasing artifacts. Users can select between three tuning variations representing different console channels, an average setting, or an "ideal" curve.
PSP Datamix A567 appeals primarily to engineers seeking authentic vintage coloration for mixing or tracking scenarios where that particular British console character enhances rather than merely corrects. It's less suitable for transparent shaping and better positioned as a character tool, a distinction that separates it clearly from modern digital EQs prioritizing neutrality. For those familiar with classic console sound, it delivers genuine emulation rather than approximation.
