Solid State Logic Pure Drive Quad
4 Microphone Preamplifiers, Converter, and USB Sound Card.
PURE DRIVE Quad utilizes the renowned SuperAnalogue PureDrive™ microphone preamp technology, originally introduced in the Solid State Logic ORIGIN console. PURE DRIVE Quad introduces a new DRIVE mode and USB connectivity, creating a 4-channel 2U rackmount unit.
SSL ORIGIN is the first classic recording console to feature the PureDrive microphone preamp. This innovative preamp maintains the clarity and dynamics of previous SSL designs while offering additional functionality. It allows for altering the sonic character to be deep, warm, and rich in harmonics, evolving with the gain. Thanks to PureDrive microphone preamps, SSL ORIGIN has made its mark in the world's finest studios. Whether capturing delicate nuances of a piano concert in PURE mode or adding warmth to recorded drum parts with DRIVE mode, PureDrive microphone preamp has become an essential tool in prestigious studios and recording facilities due to its flexibility and excellent sonic signature.
PURE DRIVE QUAD continues ORIGIN's legacy in a rackmount device, offering four microphone preamps with unique PURE and DRIVE modes from the ORIGIN console. It goes further by adding a new "asymmetric" DRIVE, advanced digital connectivity, and a built-in USB interface. PURE DRIVE QUAD provides four input impedance options for the microphone preamp, allowing sound engineers to explore different sonic characters or match the preamp impedance to the microphone. Additionally, each microphone preamp has independent +48V phantom power, polarity inversion, and high-pass filter. PURE DRIVE QUAD appears to be one of the most efficient and feature-rich external microphone preamps available, introducing numerous new sound and connection possibilities for demanding producers and recording engineers.
Three Drive Modes - One Microphone Preamp
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 crucial audio signal path of PURE DRIVE QUAD, increasing the product's durability and allowing seamless "matching" of all channels—not just stereo pairs. The use of digitally controlled analog circuits, controlled by potentiometers and electronic switches, simplifies the recall and precision of settings.
Each of the PURE DRIVE QUAD microphone preamps can be independently switched between three different DRIVE modes: Clean, Classic Drive, and Asymmetric Drive.
Clean mode features a highly regarded, low-noise SSL linear preamp, known for its ability to faithfully capture the sound source with exceptional clarity and detail.
Classic Drive is a symmetrical mode that mainly generates odd harmonics, producing the same sound character that defines the ORIGIN console.
Asymmetric Drive offers a new sound coloring option, designed specifically for the PURE DRIVE series. It makes even harmonics dominant, providing distinct rounding of sound, characteristic coloration, and softening of transients.
Advanced Connectivity Options
PURE DRIVE QUAD opens up a world of recording possibilities. Its versatile selection of analog and digital inputs/outputs makes it exceptionally high-performing and flexible microphone preamps. Whether you are recording a band in a world-class studio or adding character to tracks during production, PURE DRIVE QUAD is ideal. With the integrated USB sound card, PURE DRIVE QUAD is also perfect for project studios and field sessions where quality is paramount.
PURE DRIVE QUAD features four rear-panel combo XLR 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 insert return/ADC inputs of PURE DRIVE QUAD operate at a full line level of +24 dBu, enabling integration with other professional equipment.
Versatile digital connectivity of PURE DRIVE QUAD includes an integrated USB sound card that transports four audio channels to a DAW with resolutions up to 32 bits and a sampling rate of up to 192 kHz. Two pairs of AES/EBU outputs and one ADAT output transmit four channels with 24-bit resolution and a 48 kHz sampling rate. Cascade connection of two PURE DRIVE QUAD units is possible through the convenient ADAT LINK IN connector, providing access to a maximum of eight channels. AES and ADAT outputs can be individually used as DAW program outputs. Additionally, there is a word clock input and output with automatic clock adjustment, ensuring reliable digital synchronization.
