The Focusrite Saffire PRO 40 represents the new generation of Focusrite multi-channel FireWire/Thunderbolt audio interface. It is the best-sounding interface in its class; attentively designed with today’s project studio in mind.

buy one of the qualifying Focusrite interfaces on or after 1st September, 2015 and register it with Focusrite - yopu will be entitled to a free download of the Softube Time & Tone Pack. You must register their interface with a valid bundle code (included in the box) and qualifying purchase date on the Focusrite website to receive the Softube Pack.

Focusrite's unparalleled preamp legacy forms the foundation of this new interface, with eight award-winning Focusrite preamps. These are combined with the very latest in FireWire interfacing technology to deliver seamless integration, excellent routing flexibility and future-proof, rock-solid driver stability.

With Saffire PRO 40, sonic integrity reigns supreme. The eight Focusite preamps ensure low noise and distortion, whilst quality digital conversion and JetPLL™ jitter-reduction technology ensure pristine audio quality as your audio flows between the analogue and digital domains.

Alongside the eight Focusrite preamps are a host of additional I/O options; 10 analogue outputs, ADAT I/O, stereo S/PDIF and two virtual ‘loopback’ inputs for routing digital audio between software applications. Every channel features phantom power, with the first two channels also featuring -9dB pads for additional headroom. Front panel five-step LED metering for each analogue input offers accurate viewing of levels.

Saffire MixControl, the ultra-low-latency 18 x 16 DSP Mixer/Router software provided with Saffire PRO 40, sets a new standard at this price point for audio interface control. It features unparalleled output routing and monitoring, as well as intuitive one-click options, a clear and concise mixing layout and large on-screen metering for inputs, outputs and submixes.

Two independent headphone buses are provided, each with their own level controls available on the front panel. A dedicated stereo monitor mix output features pads for improved sound quality when connected to active monitor speakers. An 'anti-thump' circuit protects your monitor speakers from spikes when booting up or shutting down. Front panel controls include a main monitor dial with dim and mute switches, all of which fully integrate with customisable software to cover every possible monitoring need, providing a set of controls for any set-up from basic stereo to full 7.1 surround.
