Omnia-6EX HD+FM Digital Audio Processor

Supplier: Richardson Electronics

There’s a lot of buzz about the new HD Radio codec. We’ve heard it and agree with the many others who like it and say it’s now time to get on with radio’s transition to digital.

Because HD Radio and DAB systems can transmit audio frequencies up to 20kHz, listeners will finally be allowed to hear the full CD spectrum – if their radio stations choose the right on-air processor. On this point, you should know something important: Some “HD” processors simply hack off everything above 15kHz... robbing listeners of the full HD Radio experience and keeping our industry in a fidelity backwater.

 

The new Omnia-6EX won’t short-change your listeners. We’ve built Omnias with sampling rates of 48kHz and higher from the start. All along, we’ve needed the sampling headroom to keep analog FM audio grunge-free. Now it’s essential for DAB and HD Radio. Even if some listeners wouldn’t notice the missing high frequencies, there’s a fair chance they would hear a sharp 15kHz low-pass filter operating within HD Radio’s codec range.

 

Omnia-6EX has a unique 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 DAB section has a multi-band Look-Ahead final limiter with user-selectable frequency response all the way up to the full audio bandwidth of 20 kHz.

 

Omnia-6EX is also full of processing enhancements that result in yet more bass punch, yet more voice clarity, than the original Omnia-6. A sound so powerful and free of artificial constraints, you’ll crave it for your station the first time you hear it. In fact, more than 50% of the US’ Top 100 FM stations have already upgraded to Omnia. Maybe you’re next?
