Focusrite Liquid Saffire 56 Interface

Liquid Saffire 56 is Focusrite's flagship 2U multi-channel FireWire audio interface. Liquid technology combines with Saffire Pro FireWire interfacing to deliver a host of authentic pre-amp flavours, seamless software integration, excellent routing flexibility and future-proof, rock-solid driver stability.

In addition to six of Focusrite's legendary mic-pre's, two of Liquid Saffire 56's pre-amps utilises the third generation of Focusrite's Liquid Pre-amp, providing the choice of ten different pre-amp emulations. These include emulations based on the Neve 1073, the Pultec MB-1, Telefunken V72 and seven more. A harmonics dial on each Liquid pre-amp lets you account for variance in vintage originals of the same model, or use levels of 2nd, 3rd and 5th Harmonic distortion creatively to shape your sound.

Liquid Saffire 56 doesn't just offer pre-amp variety; sonic integrity is also guaranteed throughout. Both the Liquid and Saffire pre-amps ensure low noise and distortion, whilst quality digital conversion and JetPLLTM jitter elimination technology ensure pristine audio quality as your audio flows between the analogue and digital domains.

Alongside the two Liquid- and six Saffire pre-amps, are a host of i/o options; 10 analogue outputs, 16 channels of ADAT i/o, stereo SPDIF i/o, MIDI i/o and 2 virtual 'loopback' inputs for routing digital audio between software applications - ideal for capturing audio playback within your computer. Mic, Line and Instrument inputs all utilise independent connectors, with the input type for each channel selectable via custom control software. Consequently, all the inputs can remain permanently connected, ready for whatever your recording session demands. In addition, word-clock i/o is provided on BNC connectors, allowing Liquid Saffire 56 to act as either a master clock for your studio, or as a slave to an existing clock. Every channel features an independent phantom power and a high pass filter, switchable from the front panel, with the two instrument channels also featuring -9dB pads for additional headroom. Front panel 5-LED metering for all inputs, including ADAT and SPDIF, offers accurate viewing of all levels.

Saffire Mix Control, the zero-latency 18 x 16 DSP Mixer/Router software provided with Liquid Saffire 56 features unparalleled output routing and monitoring. It also provides intuitive one-click set-up solutions, a clear and concise mixing layout, large on-screen metering for inputs, outputs and submixes and control over the choice of liquid emulation.

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 the unit.

Two Liquid Pre-amps

The marriage of a hugely flexible analogue front end with cutting-edge dynamic convolution DSP, each Liquid Pre-amp lets you choose from ten different classic pre-amp emulations, with an eleventh 'flat' option.

Six High Quality Award-winning Focusrite Pre-amps

Six award-winning Saffire pre-amps complement two Liquid pre-amps. All eight pre-amps demonstrate the same wide bandwidth philosophy behind the early vintage Focusrite units.

High Quality 24-bit/192kHz FireWire Interface

Professional digital conversion and JetPLLTM jitter elimination technology; pristine audio quality and reliable synchronisation are guaranteed.

Total I/O Count of 28 Inputs and 28 Outputs

A host of i/o options are provided*, including a unique loop-back facility for routing audio between software applications via Saffire Mix Control.

Suite of Focusrite VST/AU plug-ins

Upgrade your standard sequencer effects and bring a touch of class to your session with Focusrite Compression, Reverb, Gating and EQ VST/AU plug-ins.

Two separate headphone buses

Two artists can receive independent and fully customised monitor mixes. Each output has an independent level control available on the front panel.

Saffire Mix Control Zero-latency DSP Mixer/Router

Routing flexibility and intuitive one-click set-up solutions; Saffire Mix Control provides an 18 x 16 DSP mixer with excellent output routing and monitoring capabilities.

Front panel 5-LED metering

LED metering for each of the analogue, ADAT1, ADAT2 or S/PDIF inputs offers accurate viewing of levels direct from the front fascia.

All of Focusrite's FireWire interfaces are fully compatible with Thunderbolt using a simple FireWire to Thunderbolt adapter. Focusrite fully supports the use of Thunderbolt with their FireWire interfaces.

I must admit, I am extremely impressed! After 1 full year of using the Focusrite Liquid Saffire 56, I am SOLD. At first, I experienced some issues with Firewire compatibility and a computer that was too slow, (NOT A FOCUSRITE ISSUE) once I upgraded and built a new computer to today's expected specs, I was up and running. The only technical issue was latency and driver issues, which after reading and running tests with a well known (Latency Test, 3rd Party Download) I was able to see that drivers running on my computer were spiking the time intervals which affected the Firewire interface and other processes not wanted or necessary in a DAW setup. Long story short... I am using windows 7 professional 64bit with 32gb of ram (tower build was built for around 2K) because I also wanted to do some video editing and graphics. I decided to make custom settings to allow the computer to be Protools10 only at boot with one user login and with only necessary things turned on, I made this username Protools10. For other all other programs I made a separate user account with all things left on. For Protools10 logon I turned off wireless internet, blue tooth and other pesky problems that should be apparent to most users, but not all when using a dedicated system. The results are more pleasing. The round trip latency before the dedicated user account was about from 0.200 to 0.320 max. That's not milliseconds but microseconds (looks like backwards (u.) then s. read more again (not ms.) The latency test software shows range from 0 to 16000 on their measured scale with anything under 0.500 being okay for streaming audio or video. Since that time FOCUSRITE has a new driver out 3.00 for the MixContol and it's made the latency even better and you do not have to use the legacy firewire settings that you once were more depending on to make things the best that they could be as far as latency. After installing the MixControl software 3.00, I noticed with Protools10 running and the Liquid Saffire running the latency had gone down even further to about 0.088 lowest to 0.180 highest. So if my calculations are correct that's still under .25 ms. GREAT NEWS!!! For me and for you if you are looking at the Focusrite Liquid Saffire 56. Check this link out for update. (AS OF JUNE 2012) Here's a link also to download the DPC LATENCY CHECKER (FREE) if you use it for private personal use and not commercial. Hope this helps so of you on the fence for which device to use. Best Regards, Mark
