SPECIFICATIONS
Note: All measurements made with the supplied “Proof of Perf” preset, which is available in the Preset Submenu.
System
Signal to Noise:
The measured noise floor will depend upon the settings of the Input and
Output Gain controls. The Omnia’s noise floor is primarily governed by
the dynamic range of the 24-bit Crystal Semiconductor CS5360 A/D Converter,
which has a specified Dynamic Range of 105 dB. The dynamic range of
the Omnia 3 digital signal processing chain is 144 dB. Typical SNR using
the “Proof of Perf” preset is greater than –80dB referenced to 100%
modulation.
Distortion:
No greater than 0.01% THD 20 Hz -- 20 kHz bandwidth.
FM Specifications (Omnia3-fm Turbo only)
Frequency Response:
Complies with the standard 50 or 75 microsecond pre-emphasis curve
within ± 0.50 dB, 30 Hz to 15 kHz. The analog left/right outputs and
AES/EBU Digital outputs can be configured for flat or pre-emphasized
output.
Signal-to-Noise Ratio:
> -80 dB de-emphasized, 20 Hz –- 15 kHz bandwidth, referenced to
100%
modulation).
System Distortion:
Less than 0.01% THD, 20 Hz – 7.5 kHz. Second harmonic distortion
above 7.5 kHz is not audible in the FM system
Stereo Separation:
Greater than 65 dB, 20 Hz –- 15 kHz; 70 dB typical.
Crosstalk:
> -70 dB, 20 Hz -- 15 kHz.
Composite Outputs:
Configuration: Two electrically independent outputs. Software based
level
adjustment.
Source Impedance: 10 ohms or 75 ohms, jumper-selectable. Single-ended
and floating over chassis ground.
Load Impedance: 50 ohms or greater load is suggested.
Output Level: 1.2 – 9.2 Vp-p, software adjustable.
Pilot Level: Adjustable from 6.0% to 12.0% in 0.1% steps.
Pilot Stability: 19 kHz, ± 0.5 Hz.
D/A Conversion: Burr Brown PCM1704, 24-bit sign-magnitude D/A
converter.
