Solid State Logic Pure Drive Quad

4 Microphone preamplifiers, converter and USB sound card.

The PURE DRIVE Quad uses SuperAnalogue's famous PureDrive™ microphone preamp technology, originally used in the Solid State Logic ORIGIN console. The PURE DRIVE Quad introduces a new DRIVE mode and USB connectivity to create a 4-channel 2U high rack unit.

SSL ORIGIN is the first classic recording console to feature the PureDrive microphone preamp. This innovative preamp retains the clarity and dynamics of previous SSL designs, while offering additional functionality. It consists of the ability to change the sound character to a deep, warm and harmonic sound that changes with gain. SSL ORIGIN has made its mark in the world's top studios with its PureDrive microphone preamps, among other features. Whether it's capturing the delicate nuances of a piano concerto in PURE mode or lending warmth to recorded drum parts when set to DRIVE, the PureDrive microphone preamp has become an indispensable tool in the most prestigious studios and recording facilities because of its flexibility and superior sonic signature.

The PURE DRIVE QUAD continues ORIGIN's legacy in rack unit form. It offers four microphone preamps with the unique PURE and DRIVE modes from the ORIGIN console, but also goes a step further by adding a new "asymmetrical" DRIVE, advanced digital connectivity and a built-in USB interface. The PURE DRIVE QUAD offers four microphone preamp input impedance options. It allows sound engineers to explore different sonic characteristics or match the impedance of the preamp to the microphone. In addition, each microphone preamp features independent +48V phantom power, polarity inversion and a high-pass filter. The PURE DRIVE OCTO appears to be one of the most powerful and feature-rich external microphone preamps on the market, introducing many new sonic and connectivity options for more demanding producers and recording engineers.

Three drive modes - One microphone preamplifier

PURE DRIVE QUAD is the result of SSL's commitment to progressive analog circuit design. No electromechanical components (potentiometers, mechanical switches, relays, etc.) are used in the PURE DRIVE QUAD's crucial audio signal path increasing product longevity and enabling impeccable "matching" of all channels - not just the stereo pair. The use of digitally controlled analog circuits, controlled by potentiometers and electronic switches, simplifies the recall and precision of settings.

Each PURE DRIVE QUAD microphone preamp can be independently switched between three different DRIVE modes: Clean, Classic Drive and Asymmetric Drive.

Clean mode is a highly regarded SSL linear preamplifier with a very low noise floor. It is known for its ability to faithfully capture the sound of the source with exceptional clarity and detail.

Classic Drive is a symmetrical mode that generates mostly odd harmonics; the same sound that characterizes the ORIGIN console.

Asymmetric Drive offers a new sound coloring option designed specifically for the PURE DRIVE series, making even harmonics dominant and providing a distinct rounding of sound, characteristic coloring and softening of transients.

Advanced connectivity

PURE DRIVE QUAD opens up a world of recording possibilities. A versatile selection of analog and digital inputs/outputs make these microphone preamps with exceptional performance and flexibility. Whether you're recording a band in a world-class studio or adding character to tracks at the production stage. With an integrated USB soundcard, the PURE DRIVE QUAD is also ideal for project studios and field sessions where quality is critical.

The PURE DRIVE QUAD has four rear-mounted XLR combo inputs, four front-panel HI-Z/DI instrument inputs with automatic input detection, and three sets of D-sub connectors for line inputs, as well as insert send and insert return. The PURE DRIVE QUAD insert return/ADC inputs operate up to a full +24 dBu line level, allowing interfacing with other professional equipment.

The PURE DRIVE QUAD's versatile digital connectivity includes an integrated USB sound card transporting four channels of audio to the DAW with up to 32-bit resolution and up to 192kHz sampling rate. Two pairs of AES/EBU outputs and an ADAT output, transport four channels at 24-bit resolution and 48kHz. Cascading two PURE DRIVE QUADs together is possible via a convenient ADAT LINK IN connector giving access to up to eight channels. The AES and ADAT outputs can be individually used as outputs from a DAW program. In addition, a word clock input and output with automatic timing control is available for reliable digital clocking.
