Product Description

FM

Smart wideband AGC followed by advanced Four-Band AGC and selectable Four or Five-Band Peak Limiter sections. Omnia’sadvanced, fully distortion-controlled, pre-emphasized final limiter / clipper. A newly designed digital stereo generator with SCA convenience input, two independently adjustable composite MPX outputs and 19kHz pilot output for synchronization to external RDS generators.

 

AM

Omnia’s advanced NRSC compliant, distortion-managed final limiter / clipper, including selectable Low Pass Filter frequencies that support AM HD transmission installations…the same as used in the Omnia ONE’s bigger siblings.

 

Multicast

Features SENSUS®, an audio conditioning technology to minimize codec artifacts as well as restore the fullness and depth that bit-reduction steals. See expanded explanation about SENSUS technology later in this brochure. Ultra low-distortion final limiting optimized for the HD codec.

 

Studio Pro

Full-bandwidth processor for applications that require minimal delay and do not require absolute peak limiting. The first studio processor to include a four-band compressor / limiter allowing you precise and accurately defined control while pre-processing music, commercials, remote feeds, or sweetening audio. Applications include recording studios, mastering labs, TV stations, radio headphone feeds … just abut any application where signal processing is needed.

System Frequency Response

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)

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 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.

System Distortion

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)

External Sync Input

External Sync: Allows the output sample rate to be synchronized to an AES3 signal applied to the Ext. Sync input connector. (Does not accept Word Clock inputs)

Connector: EMI-suppressed RJ-45 female according to StudioHub+® standards. Transformer isolated, balanced, and floating according to AES3 standard.
