Allstar Show Industries was recently tasked with an upgrade to the sound reinforcement system for the 685-seat Eva O. Howard Theatre at the Victoria School of the Arts in Edmonton, Alberta, Canada, with a d&b audiotechnik T-Series line array joined by 24S loudspeakers as key components in the project.
“d&b ArrayCalc processing was used for analysis by Trevor Nash at d&b, who determined that the T-Series was the best product for the space,” explains Wayne Rabidoux, CTS, Allstar Show Industries (also of Edmonton). A T-Series center array with the 24S point source loudspeakers left and right combine to deliver audio coverage throughout the facility, with additional directivity control due to the dipolar low-frequency component arrangements within the cabinets.
Rabidoux said that the building is very old and hanging the center cluster through a plaster ceiling and from a ceiling space built in the 1940s had its challenges. “Allstar chose to use beam clamps from the existing structure and passed aircraft cable through two precision cut holes,” he notes. “This was accomplished with one man on a scissor lift and one man safely nestled in the ceiling structure.”
“The theatre was built in 1947 and was the A House in Edmonton until the Jubilee Auditorium was built,” addss Nico Van Der Kley, technical director. “The theatre is used for performances by the school and is rented out to community groups so when looking for a sound system upgrade, I needed a system that is flexible and sounds great, from a talking head at a podium and a musical theatre production to a concert band and jazz band, etc. After looking at a few different options, I felt that the d&b T-Series loudspeakers provide the sound quality and performance capability that we needed for our theatre. It is definitely the best sounding venue of its size in the Edmonton area.”
The left-center-right loudspeaker system consists of seven Ti10L line array modules for the center array, two 24S 2-way loudspeakers each for left and right, five 5S 2-way coaxial loudspeakers for front fill, dual 27A-SUB subwoofers that are flown behind the center array, and four V-GSUB cardioid subs on the ground, all of which are powered and processed by four d&b 30D amplifiers.
