Digital Interface
24-bit oversampled* delta sigma Resolution:
typically 95dB A-weighted Dynamic range:
typically 92dB A-weighted (referenced Noise Floor:
to 0dBFS = +18dBu). So for a +4dBu
signal, the SNR is 78dB
0.01% @ 0dBu at 96kHz sample rate Distortion (20Hz - 20kHz):
0.02% @ 0dBu at 48kHz sample rate
0.02% @ -1dBFS at all sample rates
typically -67dB (20Hz - 20kHz) Crosstalk:
* 20kHz bandwidth sampled at 96kHz = 2.4x
Master clock frequency / sample rate = 256x at 96kHz
