Omnia 6 Performance Specifications
As of October 2003 – Version 7.0.0 Software
Note: All measurements made with the supplied “FACT TEST2” preset, which is available in the Preset
Menu.
System
Signal to Noise:
The measured noise floor will depend upon the settings of the Input and
Output Gain controls. The Omnia 6'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 6 digital signal processing chain is 144 dB. Typical SNR using
the “FactTest2” preset is greater than –80dB referenced to 100%
modulation.
Distortion:
No greater than 0.01% THD 20 Hz -- 20 kHz bandwidth.
Conventional FM Specifications (FM Analog)
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
Ranges:
Low Range: 0.66 to 5.02 V P-P, High Range: 1.45 to 11.02 V P-P,
software selectable.
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.
