Solid State Logic Pure Drive Quad 4-channel Preamplifier

 Obsessed with Analogue

The Pure Drive QUAD harnesses Solid State Logic's renowned SuperAnalogue PureDrive™ microphone preamp technology, originally featured in the ORIGIN console. This advanced unit introduces a new DRIVE mode, comprehensive connectivity, and state-of-the-art digital conversion, all within a compact 4-channel 2U rackmount format. The ORIGIN recording console, a contemporary-classic from SSL, first introduced the groundbreaking PureDrive™ microphone preamplifier. This innovative preamp maintains the clarity and punch of SSL's previous designs while also offering the flexibility to switch its character to a warm, harmonically rich, and driven tone that varies with gain.

Analogue Obsession
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.
The SSL 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.
Also, the 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.

Mic Impedance Input
Pure Drive QUAD offers four mic preamp input impedance options, enabling engineers to match the mic pre's impedance closely to the microphone or even change the tonality of the input signal (on ribbon and dynamic mics), giving further creative control when recording with the PURE DRIVE preamps.

Three Independent Gain, Trim and HPF Controls
GAIN - Stepped Gain control up to +65 dB Gain
TRIM - 31-step Trim control, with precise 1 dB increments – overdrive the signal with the Gain control and then reduce to a suitable level using Trim.
HPF - Variable High Pass filter going up to 300Hz.
