SSL - Pure Drive Quad

Mic Pre’s with Prestige
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.

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.

3 Flavours, 1 Mic Pre

PURE DRIVE QUAD is a testament to SSL's commitment to progressive analogue circuit design. No electro-mechanical components (potentiometers, mechanical switches, relays etc) are used in the critical audio signal path of PURE DRIVE QUAD, increasing product longevity, and allowing impeccable ‘matching’ between all channels – not just a stereo pair. The use of digitally controlled analogue circuits, controlled by detented pots and electronic switches simplifies recall and precision of settings. Each of PURE DRIVE QUAD’s mic pre’s can be independently switched between three distinct DRIVE modes: Clean, Classic Drive, and Asymmetric Drive.

Clean Mode Clean mode (White) delivers the highly regarded, ultra-low noise floor, linear SSL preamp that is recognised for its ability to faithfully capture the sound of the source with exceptional clarity and detail.	Classic Drive Classic Drive (Amber) is the symmetrical mode that generates predominantly odd harmonics; the same drive sound found on the ORIGIN console	Asymmetric Drive Asymmetric Drive (Green) offers up a new colouration option, specifically designed for the PURE DRIVE range, making the even harmonic content dominant and providing more pronounced thickness, colouration and softening of transients.

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.

Independent Gain, Trim and HPF Controls

PURE DRIVE QUAD features three independent 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.
