Appendix A: Performance Specifications
OmniaONE Multicast
As of January 2007 – Version 0.9 Software
Note: All measurements made using "Bypass" mode, which is available in the Input/Output
Submenu.
General Audio Specifications
Frequency Response: ± 0.50 dB, 20 Hz to 20 kHz with high pass filter disabled.
Distortion:
Less than 0.05% THD 20 Hz – 20 kHz bandwidth.
*Signal-Noise Ratio: Greater than -100 dB, 20 Hz –- 20 kHz bandwidth, referenced to 0dBfs
*The measured noise floor will depend upon the settings of the Input and Output Gain controls and is primarily governed
by dynamic range of the Crystal Semiconductor A/D Converter which is specified as >100 dB. The dynamic range of the
internal digital signal processing chain is >144 dB.
Stereo Separation: Greater than 80 dB, 20 Hz –- 20 kHz; 90 dB typical.
Analog Audio Input: Left/Right Stereo.
Electronically
balanced.
Input impedance 10k ohms resistive.
Maximum
Input
Level
+24
dBu.
Nominal Input Level: +4dBu (A +12dBu input results in –12dBFS input
meter reading with Input Gain set to 0.0dB. A 0dBu input signal results in
a -12dBFS input level when Input Gain is +12dB.)
A/D Conversion:
Crystal Semiconductor 24 bit 128x oversampled delta sigma converter
with linear-phase anti-aliasing filter. Pre-ADC anti-alias filter, with high-
pass filter at <10 Hz.
Connectors:
Two, EMI-suppressed XLR-female. Pin 1 chassis ground, Pin 2 "Hot".
Analog Audio Output: Left/Right Stereo. Electronically balanced.
Output
Impedance
20
ohms.
Minimum load Impedance 600 ohms.
Output
Level
adjustable
from
-2 dBu to +22dBu peak in 0.1dB steps.
D/A Conversion:
Crystal Semiconductor CS4390 24 bit, 128x oversampled.
Connectors:
Two, EMI-suppressed XLR-male. Pin 1 chassis ground, Pin 2 “Hot".
