SSL have announced two new 2U rack-based mic preamp products, the PURE DRIVE QUAD and PURE DRIVE OCTO. Available in 4-channel or 8-channel configurations respectively, both use SSL's SuperAnalogue PureDrive Technology, first introduced on the ORIGIN recording console. They feature a newly introduced DRIVE mode, comprehensive analog and digital connectivity options and an integrated USB-C soundcard.
The PureDrive microphone preamplifier retains the character of previous SSL designs while offering the added versatility of switching its character to a warm, harmonically rich, and driven tone that varies with gain. PURE DRIVE QUAD and OCTO bring these features into rack format, but take it further, adding a new ‘Asymmetric’ Drive, comprehensive digital connectivity, and an onboard USB-C interface. PURE DRIVE QUAD and OCTO also offer four mic preamp input impedance options, for added tonal possibilities or to match the Preamp’s impedance closely to the microphone. Additionally, each mic pre includes independent +48V phantom power, polarity inversion, and a High Pass Filter, which is sweepable on QUAD.
“The PURE DRIVE QUAD and OCTO offer a collection of features and workflows never seen before in an outboard mic pre. They stand as a testament to SSL's commitment to progressive analogue circuit design, offering exceptional performance and versatility.”
Andy Jackson, – Senior Product Manager - Studio Products
Drive Modes
There are three different DRIVE modes: Clean, Classic Drive and Asymmetric Drive. Clean mode delivers SSL's signature ultra-low noise floor, linear preamp. Classic Drive generates predominantly odd harmonics — the same drive sound found on the ORIGIN console. Finally, Asymmetric Drive makes the even harmonic content dominant, providing more pronounced thickness, colouration, and softening of transients.
Connectivity
Both units feature four front-mounted Hi-Z/DI Instrument inputs with automatic input detection, rear-mounted combo XLR inputs, D-sub connectors for line-level inputs, as well as insert send and insert return. All insert returns/ADC inputs operate up to full +24 dBu line-level, for interfacing with other professional equipment. Digitally, QUAD and OCTO feature an integrated USB-C soundcard providing conversion up to 32-Bit/192 kHz, AES/EBU outputs, and ADAT out with SMUX. The AES and ADAT outputs can be individually repurposed to be fed from the onboard USB soundcard as outputs from your DAW. Finally, there's an auto-ranging word clock input and output for robust digital clocking.
Features
Four and eight channel high-performance PureDrive mic preamps
+48V phantom power, polarity invert and 3rd order hi-pass filter (sweepable on QUAD)
Stepped Gain control up to +65 dB Gain
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.
3 modes for each preamp – Clean, Classic Drive and Asymmetric Drive
Mic/Line Input Switching
Mic via XLR
Line via choice of TRS Jack or dedicated D-Sub connectivity
4 x front panel Hi-Z/DI Instrument unbalanced inputs with automatic input detection
4 mic preamp input impedance options – explore new tonal possibilities from your dynamic and ribbon microphones
Balanced analogue outputs/insert sends for external processing
+24 dBu professional line level insert returns/ADC inputs
Analogue to digital connectivity via ADAT, AES and USB – record to your DAW in the way that best suits you
Ability to switch ADAT and AES connections to source audio from DAW outputs (USB) instead of the A/D converter
Cascade 2 PURE DRIVE QUAD units via convenient ADAT LINK IN connection
