Note: 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 Response
System Signal to Noise Ratio
*The measured noise floor will depend upon the settings of the Input and Output Gain controls and is primarily governed
by dynamic range of the Crystal Semiconductor CS5361 A/D Converter which is specified as >110 dB. The dynamic range
of the internal digital signal processing chain is >144 dB.

Omnia ONE AM
As of April 2008 – Version 2.1 AM Software
Complies with the NRSC emphasis curve within ± 0.50 dB, 30 Hz to
10 kHz. (At a setting of "10" on the HF EQ control)
-80 dB de-emphasized, 20 Hz –- 10 kHz NRSC bandwidth, referenced to
100% modulation).
Less than 0.01% THD, 20 Hz – 5 kHz. (second order harmonic
distortion above 5 kHz is not relevant in the AM system due to the
removal of harmonics by the system's 10 kHz low pass filter)
Greater than 65 dB, 20 Hz –- 10 kHz; greater than 70 dB typical.
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 nominal average level (VU reading) of +4dBu
will typically produce peak readings on the input meter in the range of -12
dBFS to -6dBFS. This is the correct operating level.
Crystal Semiconductor CS5361, 24 bit 128x over-sampled delta sigma
converter with linear-phase anti-aliasing filter. Pre-ADC anti-alias filter,
with high-pass filter at <10 Hz.
Two, EMI-suppressed XLR-female. Pin 1 chassis ground, Pin 2 "Hot".
