Digital Output Specifications
24 Bit
24-bit delta sigma using Wolfson WM8738 ADC
Sampling Rate
44.1kHz, 48kHz, 88.2kHz or 96kHz selectable
Output Formats
AES3 compliant (balanced), S/PDIF electrical, S/PDIF optical
This is [sample frequency divided by twice the bandwidth]. So for a 20kHz bandwidth sampled

at 96kHz, oversampling = 2.4x.

However the term oversampling is sometimes confused with [clock frequency divided by

sample rate]. In the DB-1 that would be 256x at 96kHz
Noise Floor typically 92dB A-weighted (referenced to 0dBFS = +18dBu). So for a

+4dBu signal, the SNR is 78dB
Distortion typically 0.01% 0dBu (20Hz - 20kHz) at 96kHz sample rate
typically 0.02% 0dBu (20Hz - 20kHz) at 48kHz sample rate
typically 0.02% -1dBFS (20Hz - 20kHz) at all sample rates
External Word Clock input: 75ohm, 1.25V - TTL level, 44.1kHz to 96kHz (auto synchronising)
Crosstalk:typically -67dB (20Hz - 20kHz)
