Technical Specification

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 1-2

  • Frequency Response: 20Hz - 20kHz +/- 0.2 dB
  • Gain Range: +13dB to +60dB
  • THD+N: 0.001% (measured at 1kHz with a 20Hz/22kHz bandpass filter)
  • Noise EIN: 124dB analogue to digital (measured at 60dB of gain with 150Ω termination 20Hz/22kHz bandpass filter)
  • Input Impedance: 2kΩ

 

Digital performance

  • A/D Dynamic Range > 109dB (A-weighted), all analogue inputs
  • D/A Dynamic Range > 106dB (A-weighted), all analogue outputs
  • Clock Sources:
    • Internal Clock
    • Sync to Word Clock on S/PDIF Input (RCA)
  • Clock jitter < 500 picoseconds
  • Supported Sample Rates: 44.1kHz, 48kHz, 88.2kHz, 96kHz
  • 8 input channels to computer: Analogue (4), Loop-back (2) and S/PDIF (2)
  • 12 output channels from computer: DAW (12)
  • 6 output channels from Scarlet 8i6: Analogue (4), S/PDIF (2)
  • 18 input by 6 output mixer.

 

Line Inputs (Inputs 1-2)

  • Frequency Response: 20Hz - 20kHz +/- 0.2dB
  • Gain Range: -10dB to +36dB
  • THD+N: 0.001% (measured with 0dBFS input and 22Hz/22kHz bandpass filter)
  • Noise: -90dBu (22Hz/22kHz bandpass filter)
  • Input Impedance: >10kΩ

 

Line Inputs 3-4

  • Frequency Response: 20Hz - 20kHz +/- 0.2 dB
  • Gain Range: Switch-able between +16dBu or -10dBV for 0dBFS (balanced inputs)
  • THD+N: 0.003% (measured at 1kHz with a 20Hz/22kHz bandpass filter)
  • Noise: -100dBu (22Hz/22kHz bandpass filter)
  • Input Impedance: >10kΩ

 

Instrument Inputs (Inputs 1 and 2)

  • Frequency Response: 20Hz - 20kHz +/- 0.1dB
  • Gain Range: +13dB to +60dB
  • THD+N: 0.004% (measured with 0dBu input and 20Hz/22kHz bandpass filter)
  • Noise: -87dBu (20Hz/22kHz bandpass filter)

 

Analogue Audio Outputs (Outputs 1-4)

  • 4 Electronically Balanced Outputs
  • Maximum Output Level (0dBFS): +12dBu
  • THD+N: 0.001% (0dBFS input, 20Hz/22kHz bandpass filter)

 

Crosstalk (Channel Isolation)

  • Any input to input: > 100dB
  • Any output to output: > 100dB
  • Any input to output: > 100dB

 

Dimensions (W x H x D)

  • Unboxed: approx. 215mm x 45mm x 220mm (8.5 x 1.8 x 8.7 inches)
  • Boxed: approx. 335mm x 275mm x 125mm (13.2 x 10.8 x 4.9 inches)

 

Weights
