Audio Specifications
1 Wherever dB values are specified, the following conventions apply:
0dBu = 0.775V RMS Reference
0dBm = 1mW (0.775V RMS) into 600 Ω
dBfs = Referenced to Digital Full Scale
dBr = Referenced to Max. Analogue Operating Level
dB = Referenced to Unity Gain
2 Noise figures are measured with a bandwidth from 20Hz–20kHz.
3 The following specifications apply with FS at 48 kHz and the internal
Operating Level set to +20dBu.
4 The measurements apply to a complete OXF-R3 system.
Sample Rates
44.1 - 48kHz +/- 12.5%
(The OXF-R3 always requires an external BNC audio word
clock and will chase a varispeed reference)
4 Ch Analogue MIC & LINE Inputs
Gain Control
• MIC -20dB to +80dB in 1dB steps
• LINE -30dB to +20dB in 1dB steps
Input Impedance
• MIC 1.5k
Ω or 100kΩ switchable
• LINE 16k Ω
Max Input Level
• MIC 50V @ 50Hz for 1 Minute
• LINE 200V DC–1kHz for 1 Minute
Noise Floor
• MIC < -124dBfs Equivalent Input Noise
(Zin = 200
Ω, Gain = 80dB)
• LINE < -108dBfs (Gain = 0dB)
CMRR
• MIC > 45dB 20Hz–20kHz (Gain = 0dB)
• LINE > 50dB 20Hz–20kHz (Gain = 0dB)
Frequency Response
• 20Hz–20kHz +/- 0.2dB
Distortion 20Hz–20kHz
• Full Scale Signal < -96dBfs (0.005% THD + N)
• -20dBfs Harmonic content < -115dBfs
