The PURE DRIVE QUAD is an advanced audio interface that brings the acclaimed SuperAnalogue PureDrive™ microphone preamp technology from Solid State Logic's ORIGIN console to a 4-channel 2U rackmount unit. This innovation eliminates electro-mechanical components from the critical audio signal path, enhancing product durability and ensuring precise matching between all channels. Each of the microphone preamps can be individually configured for three DRIVE modes: Clean, Classic Drive, and Asymmetric Drive, offering a range of tonal options from ultra-low noise clarity to pronounced coloration.The device provides comprehensive connectivity with combo XLR inputs, Hi-Z/DI instrument inputs, D-sub connectors, and an integrated USB sound card for interfacing with digital audio workstations at up to 32-Bit/192 kHz. It also includes AES/EBU and ADAT outputs, supporting cascade connections for expanded channel capacity. The inclusion of an auto-ranging word clock input and output further bolsters its capabilities for precise synchronization in complex audio setups, making the PURE DRIVE QUAD an exceptional tool for audio professionals and producers seeking versatile and high-quality recording solutions.Solid State Logic PUREDRIVE-QUAD Features:SuperAnalogue PureDrive™ Preamps with 3 Drive ModesElimination of Electro-Mechanical ComponentsIndividual Channel Control (Phantom Power, Polarity, Filter)Comprehensive Analog and Digital I/OIntegrated USB Sound CardAES/EBU and ADAT OutputsWord Clock I/OSolid State Logic PUREDRIVE-QUAD Specifications:4 channel high-performance PureDrive™ mic preamps+48V phantom power, polarity invert and sweepable 3rd order hi-pass filterStepped Gain control up to +65 dB Gain31-step Trim control, with precise 1 dB increments – overdrive the signal with the Gain control and then reduce to a suitable level using Trim.3 modes for each preamp – Clean, Classic Drive and Asymmetric DriveMic/Line Input SwitchingMic via XLRLine via choice of TRS Jack or dedicated D-Sub connectivity4 x front panel Hi-Z/DI Instrument unbalanced inputs with automatic input detection4 mic preamp input impedance options – explore new tonal possibilities from your dynamic and ribbon microphonesBalanced analogue outputs/insert sends for external processing+24 dBu professional line level insert returns/ADC inputsAnalogue to digital connectivity via ADAT, AES and USB – record to your DAW in the way that best suits youAbility to switch ADAT and AES connections to source audio from DAW outputs (USB) instead of the A/D converterCascade 2 PURE DRIVE QUAD units via convenient ADAT LINK IN connectionUSB soundcard modeQUAD – 12 in / 12 out (@44.1/48 kHz)4 x analogue + 8 x ADAT in (via Link in) / 4 AES + 8 ADAT outsStepped pots and digitally controlled analogue electronics for precision, stereo matching and ease of recallUp to 192 kHz and 32-bit conversion, professional I/O levels (+24 dBu = 0 dBFS).Selectable Auto-Sleep modeAuto-ranging Wordclock In and Out Solid State Logic PureDrive Quad 4-Channel Mic Preamps with 192 kHz/32-Bit Conversion.
