Quick Overview

Professional 20 in / 20 out Firewire interface with eight Focusrite preamps

More Views



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