Are you an audio engineer, looking for a new multi-channel FireWire audio interface? One of the most advanced ones that won’t break the bank is Focusrite’s Saffire Pro 40. Let’s check it out!

What is the Saffire Pro 40?

The Focusrite Saffire Pro 40 is part of the most recent generation of multi-channel FireWire audio interfaces. In its class of inexpensive, reliable interfaces, it is one of the best out there. The quality is above any other in its class.

Focusrite’s original legacy started with preamps, and that is basis of this new interface. It contains 8 of Focusrite’s award-winning preamps. Routing flexibility and solid driver stability are at the core of the Saffire Pro 40.

What features does the Saffire Pro 40 have?

The Saffire Pro 40 has a variety of different features that make it one of the most unique and reliable multi-channel audio interfaces out there. Let’s take a look at them.


–          Microphone: 20Hz – 20kHz +/- 0.1 dB Frequency response, Noise: EIN > 125dB (128dB analogue to digital) (measured at 60dB of gain with 150 Ohm termination (20Hz/22kHz bandpass filter)

–          Line: 20Hz – 20kHz +/- 0.1dB Frequency Response, Noise: -90dBu (22Hz/22kHz bandpass filter)

–          Instrument: 20Hz – 20kHz +/- 0.1dB Frequency Response, Noise: -87dBu (20Hz/22kHz bandpass filter)

Conversion Performance: A dynamic range of 110 db (A-weighted), with a clock jitter of <250 picoseconds.

Front and rear connectivity: For ease of access and to make most use of the space that the interface has, there are inputs and outputs in both the front and the back of the interface.

Analogue Channel Inputs:

–          Contained in inputs 1-8

–          Inputs 1 and 2 are 2 Mic/Line/Inst combo XLR’s

–          Inputs 3-8 are Mic/Line combo XLR’s

–          Inserting the jack switches the interface from Mic to Line or Instrument automatically.

Digital Channel Inputs:

–          Contained in inputs 9-18 (44.1-96kHz)

–          Stereo S/PDIF inputs on RCA

–          8 ADAT inputs, reduces to 4 if being used at 88.2 or 96 kHz. Software preferences can switch this to whatever you may need, depending on what you’re doing.

Analogue Audio Outputs:

–          Outputs 1-10

–          Outputs 1 and 2 are monitor mix outputs on ¼” TRS Jack

–          Outputs 3-10  are 8 ¼” TRS Jacks

–          Outputs 7 and 8; 9 and 10 are headphone mixes 1 and 2, respectively, on ¼” TRS Jacks

Digital Channel Outputs:

–          Outputs 11-20

–          Stereo S/PDIF output on RCA

–          8 ADAT outputs, reduces to 4 at 88.2 and 96 kHz. Can be adapted in software preferences.

Miscellaneous inputs and outputs:

–          2 6-pin FireWire sockets

–          2 Standard 5-pin DIN MIDI connectors: In and Out

–          IEC mains power input connector

Along with being lightweight and easy to use, all of these different specs (which yes, I know may not make sense to you if you aren’t exactly a professional audio engineer) make this the ultimate in Focusrite’s state of the art technology. Each feature makes your ability to mix and jam a lot more customizable than it would be with other multi-channel audio interfaces in this same price range.

Is the Saffire Pro 40 for me?

If you are looking for a multi-channel firewire audio interface, the Saffire Pro 40 may be the best choice for you. It’s light, it’s compact, it’s easy to use. Still don’t believe me? Check out these reviews from happy Saffire Pro 40 customers!

“Great firewire interface recording unit. I am using this with Windows 7 64 bit and Sonar 8.5.3 Professional Edition. I have tried many different interface units and the Saffire Pro 40 has been the easiest to install and use. The preamps are very good and better than other units I tried.” – Jack S.

“Excellent audio interface, especially at this price range. I primarily use mine for a theatre playback interface, utilizing the outputs, but also have used it as a recording interface and often as a standalone pre, sending mic signals out over the ADAT port to expand a system for live mixing. The box sounds excellent, easy to setup, no driver issues, and a easy to use computer GUI.” – Bill S.

“This interface far exceeded my expectations. The preamps sound very true to the sound source with no coloring from what I could tell. here is no latency and everything I have recorded with it so far has been excellent and everyone who has heard the results has been just as happy. I would recommend this in a heartbeat to anybody looking for an interface in this price range.” – Matt C.

So, happy audio engineers and other professionals definitely means that the Saffire Pro 40 is worth giving a try, huh? Check it out today!
