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): 109dB
• SNR (A-weighted): -109dB
• Frequency Response: 20Hz - 20kHz +/- 0.1 dB

• 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

CONNECTIVITY
Analogue Channel Inputs (Inputs 1-8)
