PURE DRIVE OCTO harnesses the renowned SuperAnalog PureDrive(TM) microphone preamp technology originally featured in Solid State Logic's ORIGIN console, introduces a new DRIVE mode and connectivity, and makes it available in a 4-channel 2U rackmount unit. SSL's contemporary-classic recording console, ORIGIN, introduced the PureDrive microphone preamplifier. This innovative preamp retains the clarity and punch of previous SSL designs while offering the added versatility of switching its character to a warm, harmonically rich, and driven tone that varies with gain. ORIGIN, along with the PureDrive microphone preamp, has made its mark in the world's premier studios. Whether it's capturing the delicate nuances of a piano concerto in PURE mode or imparting warmth on a drum recording when set to DRIVE, the PureDrive microphone preamp has become an essential tool in some of the most prestigious studios and recording facilities due to its flexibility and superb sonic signature. PURE DRIVE QUAD continues the legacy into rack format, delivering four microphone preamps with ORIGIN's renowned PURE and DRIVE modes, but takes it further, adding a new 'Asymmetric' DRIVE, advanced digital connectivity, and an onboard USB interface. PURE DRIVE QUAD offers four mic preamp input impedance options, enabling engineers to explore various tonal possibilities or match the mic pre's impedance closely to the microphone. Additionally, each mic pre includes independent +48V phantom power, polarity inversion, and a sweepable High Pass Filter. PURE DRIVE QUAD stands as one of the most capable and feature-rich outboard microphone preamplifiers available, introducing a host of new sonic possibilities and workflows for the discerning producer and recording engineer.
