We always quote 'real world' performance figures (measured to the AES17 standard). Some companies choose to quote chipset performance, which is misleading, and here's why.

Microphone Inputs

  • Dynamic Range (A-Weighted): 106dB
  • SNR (A-weighted): -105.3dB
  • Frequency Response: 20Hz - 20kHz +/- 0.1 dB
  • THD+N: 0.001% (measured at 1kHz with a 20Hz/22kHz bandpass filter)
  • Noise: EIN > 125dB (128dB analogue to digital) (measured at 60dB of gain with 150 Ohm termination (20Hz/22kHz bandpass filter)
  • Maximum level (A-weighted): 8.6dBu at 1%

Line Inputs

  • Dynamic Range (A-Weighted): 106.5dB
  • SNR (A-weighted): -106dB
  • Frequency Response: 20Hz - 20kHz +/- 0.1dB
  • THD+N (A-Weighted): < 0.001% (measured with 0dBFS input and 22Hz/22kHz bandpass filter)
  • Noise: -90dBu (22Hz/22kHz bandpass filter)
  • Maximum level (A-weighted): 16.3dBu at 1%

Instrument Inputs

  • Frequency Response: 20Hz - 20kHz +/- 0.1dB
  • THD+N: 0.004% (measured with 0dBu input and 20Hz/22kHz bandpass filter)
  • Noise: -87dBu (20Hz/22kHz bandpass filter)

Line level Outputs

  • Dynamic Range (A-Weighted): 105dB
  • SNR (A-weighted): -104.5dB
  • THD+N: < 0.001% (measured with 0dBFS input and 22Hz/22kHz bandpass filter)
  • Maximum level (A-weighted): 16.13dBu at 0.885%

Additional Conversion Performance

  • Clock jitter < 250 picoseconds
  • THD+N AMPL (A-weighted)= -107dBFS

CONNECTIVITY

Analogue Channel Inputs (Inputs 1-4)

  • 2 x XLR Mic/Line high quality Combi-Jacks (Inputs 1-2) 
  • 2 x XLR Instrument high quality Combi-Jacks (Instrument on inputs 1 and 2 only) Automatic switch of Mic / Line (inserting a jack switches from Mic to either Line or Instrument (instrument selected via the software control panel)Line inputs 3-4 have low and high gain settings can be controlled from the Saffire MixControl software (low gain being the default)

Digital Channel Inputs (Inputs 5-14) 44.1-96kHz

  • Stereo S/PDIF input on RCA
  • 1 x 8 channel ADAT input on Optical Connector (SDPIF 3&4 set in preferences menu)

Analogue Audio Outputs (Outputs 1-6)

  • 6 x TRS analogue outputs (Outputs 1-6)
  • 2 x TRS stereo headphone output (headphone mix 1 same as outputs 3 & 4, headphone mix 2 same as outputs 5 & 6)

Digital Channel Outputs (Outputs 7-8) 44.1-96kHz

  • Stereo S/PDIF output on RCA

Other I/O

  • 1x 6 pin FireWire 400 socket - also compatible with FireWire 800 and Thunderbolt
  • 2 Standard 5-pin DIN MIDI connectors: In and Out
  • 12V DC power input connector for use with external PSU

Weight and Dims

  • 1.6kg / 3.5 lbs
  • 215mm / 8.5" (W) x 45mm / 1.8" (H) x 220mm / 8.65" (D)
