The Kitchener
Memorial Auditorium (The Aud) design specs called for a sound p.a.
system capable of providing voice, foreground and background music amplification
for its 6000 seat arena. Our design replaced its existing sound system to a
central cluster TOA Z-drive system, driven by 9 TOA 1090
amplifiers controlled by a TOA ACF1 processor, and eq'd with a TOA
E1231 31 band equalizer.
To ensure smooth coverage of the seating, Paul Reibling designed an 18
speaker array, where six speakers on the sides covered the lower and
higher seating levels, and two speakers on each end covered end seating
zones, as well as providing sound for the guest boxes.

The location
of the speakers was limited by the recent installation of a
prominent video scoreboard, which could not be blocked by
speakers. This meant the speakers had to be located above the
scoreboard, and had to be carefully aimed so that high frequencies
were not blocked by structural elements of the arena, as well as
hanging banners from the ceiling. The system was aided by the
presence of sound-absorbing insulation which had been applied to the
ceiling of the arena to prevent heat transmission, but which greatly
reduced the ambient reverb time of the hall.
The system is now capable of
delivering clear voice and music communication throughout the arena
for any type of event, and signal source.

The Waterloo
Pentecostal Assembly church seats 700 people in a fan-shaped
configuration. Worship services feature a live band playing
contemporary Christian music, so the sound system was spec'd to
deliver full-range concert performance sound. A JBL array was
designed, incorporating 4892 mains, 4893 subs, and driven by MPX
amplifiers-- 1200 watts subs, 1200 watts mids and 600 watts
highs. The system is, fed by a Spirit Live 8 console and
controlled by a DSC 280 digital controller.

The location
of the speakers was determined with CADP, and then aligned after
installation using MLSSA. The three cluster array provides
excellent room coverage, with the subs located below the worship
platform. The largely untreated reflective room surfaces
presented a challenge to keep early reflections from degrading
speech intelligibility and this was overcome by careful selection of
the loudspeaker's dispersion pattern relative to the room
dimensions. |
