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.

- Dynamic Range (A-Weighted): 109dB
- SNR (A-weighted): -109dB
- 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): 8dBu at 1%
Line Inputs
- Dynamic Range (A-Weighted): 109dB

Line level Outputs
- Dynamic Range (A-Weighted): 108dB
- SNR (A-weighted): -108dB
- THD+N: < 0.001% (measured with 0dBFS input and 22Hz/22kHz bandpass filter)
- Maximum level (A-weighted): 15.7dBu at 0.883%
Additional Conversion Performance
- Clock jitter < 250 picoseconds

CONNECTIVITY
Analogue Channel Inputs (Inputs 1-8)
- 2 Mic/Line/Inst Combo XLR (Inputs 1 and 2)
- 6 Mic/Line Combo XLR (Inputs 3-8)
- Automatic switching of Mic / Line (e.g. inserting a jack switches from Mic to either Line or Instrument)
Digital Channel Inputs (Inputs 9-18) 44.1-96kHz
- Stereo S/PDIF input on RCA
- 8 ADAT inputs on Optical Connector, reduces to 4 inputs at 88.2/96kHz • Optical input can be switched to S/PDIF 3/4 in software preferences (Both ADATs and S/PDIF over RCA input disabled)
Analogue Audio Outputs (Outputs 1-10)
- 8 ¼” TRS Jack (Outputs 3-10)
- 2 monitor mix outputs on ¼” TRS Jack (Outputs 1 and 2)
- Stereo headphones mix 1 on ¼” TRS (also routed to outputs 7 & 8)

Digital Channel Outputs (Outputs 11-20) 44.1-96kHz
- Stereo S/PDIF output on RCA
- 8 ADAT outputs on Optical Connector, reduces to 4 outputs at 88.2/96kHz
- Optical output can be switched to S/PDIF 3/4 in software preferences (ADATs disabled)
