The QSC screen channel system
The Toronto International Film Festival (TIFF), adopted a more permanent home at the city’s landmark Ryerson Theatre this year; but first, an acoustic design team gave the venue’s loudspeaker system through a serious makeover.
In 2004, the historic Ryerson went through its first series of upgrades, transforming the venue from a live performance space into a world-class cinema hall.
This year the Toronto International Film Festival enlisted the services of an acoustic design team including Neil Muncy, Andy Condon and Peter Harper. Muncy, president of Neil Muncy Associates in Markham, Ontario, has been involved with the TIFF for the past 15 years. Harper is a mix and recording engineer who helped to oversee the installation and documented the venue’s equipment and wiring. Andy Condon is a computer engineer and former IT manager for a post-production house.
“The Ryerson was built in the 1950’s, with an interior consisting of marble, granite, and other highly reflective surfaces,” explains Muncy. “The acoustical treatment scheme included a modular THX wall made of conventional materials with the screen channel loudspeakers on a plane that focused the sound towards the audience.”
The original sound system, provided by Montreal-based SF Marketing, featured QSC Audio’s Digital Cinema Speaker (DCS) Series and was QSC’s first complete, end-to-end cinema installation in Canada. Thirty QSC SR-110 surround sound loudspeakers were each individually wired back to a total of four QSC DCA 1644 amplifiers located in the projection booth.
This year, the original screen channel system was upgraded to include three of QSC’s SC-443 Cinema Loudspeaker Systems, each comprising an MH-1075 mid-high system featuring a high output, horn loaded 10-inch midrange cone driver and a 3-inch titanium diaphragm compression driver, as well as two LF-4215s, each with dual 15-inch low-frequency enclosures specifically designed for the extended low-frequency requirements of cinema applications.
Each screen channel is tri-amplified using a QSC DCM-3 digital cinema processor for all three channels and the subwoofers. Screen channel power amplifiers—three QSC DCA 3022 and three QSC DCA 3422—are located backstage to minimize the length of speaker level cabling.
