DaySequerra provided its DownMix, UpMix and NLC5.1ST products featuring DTS-Neural Surround technologies for a Colorado Public Radio live broadcast of a Colorado Symphony Orchestra concert featuring cellist Yo-Yo Ma.
The Dec. 2 performance was encoded in DTS-Neural Surround and broadcast live from Denver’s Boettcher Concert Hall. The CSO performed three Dvorak pieces including the Othello Overture; after the short intermission, Yo-Yo Ma performed Dvorak’s Cello Concerto in B minor.
Mike Pappas, KUVO chief engineer and lead recording engineer on the project, said the team used DaySequerra’s DownMix surround encoder because it allowed Colorado Public Radio to transport the 5.1 surround broadcast through its existing stereo infrastructure using the DTS Neural Surround process.
The DaySequerra surround encoder and decoder allows listeners who own 5.1 home theater receivers to experience surround sound, and, at the same time, the encoder/decoder maintains compatibility with each analog and HD Radio, according to Pappas.
The event was recorded in discrete PCM as well as high-bit-rate DSD using prototype Neumann KM133D microphones; a vintage Neumann U67 was used to spotlight Yo-Yo Ma’s performance. Pappas’ team used a Digico DS00 control surface and Avalon Acoustics studio monitors powered by 1KW Jeff Rowland monoblock amplifiers.
