SPECIFICATIONS

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.
No greater than 0.01% THD 20 Hz -- 20 kHz bandwidth.
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.

Less than 0.01% THD, 20 Hz – 7.5 kHz. Second harmonic distortion
above 7.5 kHz is not audible in the FM system
Greater than 65 dB, 20 Hz –- 15 kHz; 70 dB typical.
> -70 dB, 20 Hz -- 15 kHz.
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.
Signal-to-Noise Ratio: -85 dB typical, 75 µS de-emphasized, 15 kHz
bandwidth, referenced to 100% modulation).
Distortion: < 0.02% THD 20 Hz – 15 kHz bandwidth, 75 µS de-
emphasized, referenced to 100% modulation.
Stereo Separation: > 65 dB, 30 Hz – 15 kHz.
Linear Crosstalk: > -80 dB, main to sub or sub to main channel
(referenced to 100% modulation).
Non-linear Crosstalk: > -80 dB, main to sub or sub to main channel
(referenced to 100% modulation).
38 kHz Suppression: > 70 dB (referenced to 100% modulation).
