Focusrite Saffire 6 USB
Two hundred dollars, two mic pres, and a hard ceiling at 48kHz. A bus-powered interface that chose quality over a features list.
Overview
The Saffire 6 USB is a compact, bus-powered USB interface that runs off the computer's own power. It has two Focusrite mic pre/instrument inputs and MIDI in and out. MSRP was roughly $249, but the street price was about $200, as EQ Magazine (September 2010, p.52) reported at launch. Focusrite's own advertising billed it as "the best sounding, best performing interface in its class." That's marketing copy, not a verdict, but the spec sheet shows the thinking: strip the feature set down and spend the money on the parts that touch the signal.
In practice that means a 24-bit/48kHz ceiling. The Saffire 6 USB does not chase higher sample rates. EQ Magazine (September 2010, p.52) framed that as a deliberate trade - the limitations, in the reviewer's words, were chosen to keep the price down while keeping quality up on the most important elements. For a laptop DJ, a solo musician at a desk, or anyone capturing a stereo live recording, that's a fair bargain. Someone who needs 96kHz or more inputs needs a different box, and Focusrite was upfront about that.
The connectivity shows who it was built for. The rear panel has 1/4-inch phone outputs, RCA phono outs aimed at DJ rigs, and physical MIDI connectors. That's a checklist for the laptop performer more than the project studio. The two mic pres are the headline, since Focusrite built its reputation on preamp design, but the four phono outputs and flexible monitoring are what let the Saffire 6 USB slot into a DJ setup without a pile of adapters. Mix (July 2010, p.17) ran the Saffire 6 USB in the same family spread as the Liquid Saffire 56 and the Saffire PRO 40, positioning it as the entry point to a range built around the company's preamp heritage.
Software support was broad for its day, and it's the practical question for anyone buying used. The interface shipped with ASIO/WDM drivers on Windows and Core Audio on Mac. It worked across 32- and 64-bit Windows Vista, XP SP2, and 7, plus Mac OS X 10.5.7 or higher, with the caveat that Snow Leopard ran 32-bit only. The bundled software was generous: Ableton Live Lite 8, the Focusrite plug-in suite covering compression, reverb, gating, and EQ, a gigabyte of samples from LoopMasters, 572 drum loops, and the Novation Bass Station plug-in. EQ Magazine (September 2010, p.52) singled out the Focusrite plug-ins as very good and noted they brought something different to the table regardless of how many plug-ins a user already owned. That's a rare thing to say about pack-in software.
The period press named the caveats. The interface is only partly intuitive, and reviewers advised keeping the manual close for the "secret sauce" functions. The 48kHz ceiling is real and stays. By late 2012 Focusrite itself had moved on: Pro Audio Review (October 2012) announced that the Scarlett 2i4 replaced the Saffire 6 USB, with the Scarlett range bringing the same award-winning preamps into a tough uni-body aluminum case and pushing conversion to 24-bit/96kHz. The Saffire 6 USB is the end of a particular line, not the beginning of one.
Today it's a bus-powered two-pre interface with real MIDI, DJ-friendly phono outs, and Focusrite preamps for very little money. That holds only if the drivers still cooperate with a modern machine, which decides everything with interfaces of this vintage. The bundled software licenses and the physical MIDI ports age best. The sample-rate ceiling and the 32-bit Snow Leopard limitation age worst.
