123Omnia.ONE AMNote: Discrete I/O measurements have been made in "Bypass" mode (available in the Input/Output menu).Note: All measurements made with the supplied “FACT_TEST” preset, which is available in the Preset Submenu.System Frequency ResponseComplies with the NRSC emphasis curve within ± 0.50 dB, 30 Hz to10 kHz. (At a setting of “10” on the HF EQ control)System Signal to Noise Ratio-80 dB de-emphasized, 20 Hz –- 10 kHz NRSC bandwidth, referenced to 100%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.System Distortion: Less than 0.01% THD, 20 Hz – 5 kHz. (second order harmonic distortion above 5 kHz isnot relevant in the AM system due to the removal of harmonics by the system's 10 kHzlow pass filter)System Stereo SeparationGreater than 65 dB, 20 Hz –- 10 kHz; greater than 70 dB typical.Analog Audio Input:Left/Right Stereo.Electronically balanced.Input impedance 10k ohms resistive.Maximum Input Level: +22 dBu.Nominal Input Level: +4dBu, which nets a -18dBFS input meter reading on a steady-state signal when the Input Gain control is set to 0.0dB. Program material with a nominalaverage level (VU reading) of +4dBu will typically produce peak readings on the inputmeter in the range of -12 dBFS to -6dBFS. This is the correct operating level.A/D Conversion: Crystal Semiconductor CS5361, 24 bit 128x over-sampled delta sigmaconverter 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 CS4391, 24 bit, 128x oversampled.Connectors: Two, EMI-suppressed XLR-male. Pin 1 chassis ground, Pin 2 “Hot".Digital Audio Input: Configuration: Stereo per AES/EBU standard, CS8420 Digital Audio Transceiver with24 bit resolution, software selection of stereo, mono from left, mono from right or monofrom sum. Automatically accepts and locks to input sample rates between 32 and 108kHz.
