117Appendix A: Performance SpecificationsOmnia.ONE FMNote: Discrete I/O measurements have been made in "Bypass" mode (available in the Input/Output menu). FMcomposite measurements have been made using the "Proof_Perf" preset.General Audio SpecificationsFrequency 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 beconfigured for flat or pre-emphasized output.System Distortion: Less than 0.01% THD, 20 Hz – 7.5 kHz. Second harmonic distortionabove 7.5 kHz is not audible in the FM system.*Signal-Noise Ratio: > -80 dB de-emphasized, 20 Hz –- 15 kHz bandwidth, referenced to100% modulation).*The measured noise floor will depend upon the settings of the Input and Output Gain controls and is primarily governedby dynamic range of the Crystal Semiconductor CS5361 A/D Converter which is specified as >110 dB. The dynamic rangeof the internal digital signal processing chain is >144 dB.Stereo Separation: Greater than 65 dB, 20 Hz –- 15 kHz; 70 dB typical..Crosstalk: > -70 dB, 20 Hz -- 15 kHz.Composite Outputs: Source Impedance: 5 ohms or 75 ohms, jumper-selectable. Single-endedand floating over chassis ground.Output Level: 0V to 10V in 0.05V steps, software adjustable.D/A Conversion: Texas Instruments/Burr Brown PCM1798, 24-bit sigma-delta converter.Configuration: Two electrically independent outputs. Software based leveladjustment.Load Impedance: 50 ohms or greater load is suggested.Pilot Level: Adjustable from 4.0% to 12.0% in 0.1% steps and OFF.Pilot Stability: 19 kHz, ± 0.5 Hz.Signal-to-Noise Ratio: -85 dB typical, 75 μS de-emphasized, 15 kHzbandwidth, 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).76 kHz Suppression: > 80 dB (referenced to 100% modulation).Pilot Protection: > -65 dB relative to 9% pilot injection, ± 1 kHz.57 kHz (RDS/RBDS) Protection: better than -50 dB.Connectors: Two EMI suppressed female BNC, floating over chassis ground.Maximum Load Capacitance: 5nF (at 10 ohms source impedance).Maximum cable length: 100 feet/30 meters RG-58A/U.Analog Audio Input: Left/Right Stereo.
