Solid State Logic Pure Drive Quad – Professional Mic Preamps and USB Audio Interface in One

SSL Pure Drive Quad is a 4-channel microphone preamplifier featuring PureDrive™ modes, an integrated USB audio interface, and extensive digital connectivity. It combines SSL’s legendary SuperAnalogue sound with modern studio functionality, making it perfect for high-end recording in both professional studios and project setups.

Heritage of SSL ORIGIN in a Rack Format

The Pure Drive Quad builds on the SSL ORIGIN console, the first to feature PureDrive preamps. Users can shape their sound from ultra-clean and transparent (PURE mode) to harmonically rich and warm (DRIVE mode). A new Asymmetric Drive option further expands tonal possibilities, offering more color and texture for creative production.

Three Drive Modes – One Preamplifier, Multiple Characters

• Clean – SSL’s classic linear preamp with ultra-low noise and exceptional transparency.
• Classic Drive – symmetrical mode generating odd harmonics, delivering the tone of the ORIGIN console.
• Asymmetric Drive – a new PureDrive mode emphasizing even harmonics, rounding transients and adding warmth.

Advanced Design and Reliability

The SSL Pure Drive Quad uses digitally controlled analog circuitry with no electromechanical components in the signal path. This ensures durability, precise recall, and perfect channel matching. Step gain adjustment with 1 dB precision allows consistent and accurate control across all four channels.

Flexible and Creative Options

Each of the four microphone preamps includes:

• Independent +48V phantom power,
• Polarity inversion,
• High-pass filter,
• Four switchable input impedance settings for sonic variety and mic matching.

Comprehensive Connectivity

The Pure Drive Quad offers versatile I/O options:

• 4 rear combo XLR inputs,
• 4 front Hi-Z/DI inputs with auto detection,
• D-sub connections for line inputs and insert send/return,
• Professional +24 dBu analog outputs,
• USB audio interface, AES/EBU, and ADAT outputs,
• Word Clock in/out with auto-sync.

The integrated USB audio interface streams 4 channels to your DAW at up to 32-bit/192 kHz. AES/EBU and ADAT outputs support up to 48 kHz/24-bit. Two units can be cascaded via ADAT LINK, expanding to 8 channels. Digital outputs can also be routed from your DAW for flexible workflow integration.
