has a 7.1 monitor array from PMC.
Irvine, CA (January 6, 2009)–Dolby Laboratories, Inc. has updated its Playback Reference Suite with a 7.1 monitor array from PMC, The Professional Monitor Company.
The Playback Reference Suite was recently upgraded with a pair of PMC MB2-XBD monitors for the left and right channels, plus an MB2 for the center channel. Surrounds are covered by six PMC Wafer 2 flat-panel loudspeakers. The front cabinets are powered by a trio of Bryston 7BSST amplifiers and the surrounds by a single Bryston Model 875 multizone amplifier.
Dolby’s re-equipped Playback Reference Suite was first used at CEDIA Expo 2008 in Denver, CO; it will also be seen at this month’s CES 2009 in Las Vegas.
According to John Loose, Dolby’s Senior Manager, A/V and Print Production, the 13-by-17 foot Playback Reference Suite seats a dozen participants who can view a short program of surround-sound playback from a variety of sources. “For the recent upgrade, we were looking for loudspeakers that offer a combination of power and sonic beauty. At CEDIA 2008 we used a number of discrete 7.1-channel 24-bit/96 kHz mixes from Blu-ray Disc, including a stunning performance by the San Francisco Symphony of Stravinsky’s The Rite of Spring. We also had a Dolby Volume demonstration that included a segment of the Pride & Prejudice soundtrack, which features a very wide dynamic range.”
In addition to three loudspeakers up-front, the 7.1-channel format involves both left-side and right-side playback channels, plus conventional left-rear and right-rear channels. A pair of Wafer 2 loudspeakers handle playback for each of the side channels, while single Wafer 2s cover the left and right rears. The entire playback system was calibrated by acoustician Bob Hodas of Bob Hodas Acoustic Analysis.
“The LCR playback offers plenty of low-frequency response,” says Loose. “And the flat-panel speakers provide a very smooth transition from the front to the rear. All in all, the system produces a very powerful sound, which is critical for demonstrating the 7.1-channel experience.”
