Omnia Audio announces a new line of audio processors for radio stations upgrading to HD Radio broadcasting: Omnia-6 EXi for FM and Omnia-5 EXi for AM and FM broadcasters. The new EXi processors reportedly enhance and simplify the HD Radio audio chain and add new tools for HD Radio broadcasts while increasing the clarity and listenability of conventional AM and FM broadcasts. An onboard Diversity Delay method simplifies and protects the broadcast signal of HD Radio for AM and FM, and an advanced new clipper design was engineered to help eliminate intermodulation distortion (IMD).
Omnia-6 EXi HD+FM has a parallel processing structure that routes audio from the mixer section to separate output stages for conventional FM and DAB. The FM section receives distortion-controlled final limiting with pre-emphasis and an upper-frequency response of 15 kHz. The HD Radio/DAB section has a multiband look-ahead final limiter with user-selectable frequency response all the way up to the full audio bandwidth of 20 kHz. Omnia-6 EXi features 96kHz, 24-bit resolution, six bands of limiting, five AGC bands and wideband AGC.
Omnia-5 EXi HD+FM features the same parallel processing paths as the Omnia-6, with two bands of AGC, wideband AGC and a 5-band limiter. Like the Omnia-6 EXi, its FM section features distortion-controlled final limiting with pre-emphasis and an upper-frequency response of 15 kHz; HD Radio/DAB section features Omnia’s program-adaptive look-ahead limiter; frequency response is user-selectable up to 20 kHz.
Omnia-5 EXi HD+AM’s dual processing structure routes audio from the multiband mixer section to separate, simultaneous output stages for analog and digital transmission. The HD Radio/DRM section contains Omnia’s program-adaptive look-ahead limiter, adjustable lowpass filtering and high-shelf EQ. Conventional AM is processed with an AM-optimized, distortion-cancelled final limiter with unique feedback/feed-forward design for larger, warmer bass and open, natural highs.
Omnia EXi processors will be unveiled at the 2005 NAB Convention in Las Vegas; owners of existing Omnia-6, Omnia-5 and Omnia-4.5 processors can purchase an upgrade to add full EXi capabilities to their processors. To hear the new Omnia EXi processors, visit Telos Systems/Omnia Audio at booth #N2816 during NAB 2005
In addition, Omnia president Frank Foti will present his treatise on surround sound for FM HD radio, entitled “The Killer App for FM: Distinct 5.1 Surround Sound,” on Sunday, April 17, 2005, at 10 a.m. Telos president Steve Church and Axia president Michael Dosch will present “Studio Structures for Surround Broadcasting” on Monday, April 18, 2005, at 1:30 p.m.
