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

• Input Impedance: 2kΩ
DIGITAL PERFORMANCE
• A/D Dynamic Range > 110dB (A-weighted), all analogue inputs
• D/A Dynamic Range > 106dB (A-weighted), all analogue outputs

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 1-2)
• 2 Electronically Balanced Outputs
