Note
Wherever dB values are specified, the following conventions apply:
0 dBu 0.775 V r.m.s. reference
1 mW (0.775 V r.m.s.) into 600 Ω
0 dBm
dBfs referenced to digital full scale
dBr referenced to max. analogue operating level
dB referenced to unity gain
* Noise figures are measured with a bandwidth from 20 Hz to 20 kHz
Sample Rates
44.1 kHz to 48 kHz ± 12.5%
(The OXF-R3 always requires an external BNC audio word clock)
