Non-Matrixed Surround Sound Demo Planned

Non-Matrixed Surround Sound Demo Planned

Several companies are banding together for what they say is the first live demo of non-matrixed 5.1 surround sound for FM HD Radio.
Telos/Omnia/Axia, Fraunhofer, Broadcast Electronics, Bose and ENCO Systems are cooperating on the demos to involve both the Axia and Telos/Omnia booths in the radio/audio hall at the upcoming NAB convention.
The demonstration begins in the Axia booth (N3616) with an ENCO DADPro32 delivery system and will be mixed in discrete 5.1 surround sound using Axia’s new Element control surface.
The signal will then be passed over a BE Big Pipe STL link to the Telos/Omnia booth (N2816), where it will be encoded for surround by Fraunhofer software, processed with an Omnia-6EXi HD+FM audio processor, and then broadcast on an HD Radio channel using a BE FXi 60 HD Radio Exciter.
A Visteon car radio modified by Fraunhofer will receive and decode the over-the-air signal for 5.1 surround loudspeakers.
Telos/Omnia/Axia and Fraunhofer also will plan an over-the-air demonstration of discrete surround for HD Radio in NAB’s Surround Pavilion (Booth C3607D) in the Central Hall. In a setup similar to that in the Radio Hall, visitors will be able to audition surround audio in a car via a prototype Bose 5.1 Cabin Surround sound system inside an Acura SUV.
Telos Systems Founder/CEO Steve Church states, “We will show that genuine, non-matrix surround is practical and doable today.”
