Sapphire Sound Provides d&b xS-Series Components for Lobby Areas of Calgary’s Jack Singer Concert Hall

FOH Staff • News • August 13, 2020

CALGARY, Alberta, Canada – Sapphire Sound upgraded the audio systems used for the main floor and dress circle lobbies of Calgary’s Jack Singer Concert Hall, a centerpiece of the Arts Commons complex, with d&b audiotechnik xS-Series point source loudspeakers.

More details from d&b audiotechnik (www.dbaudio.com):

Arts Commons is one of Canada’s largest and most vibrant arts centres. Located in the heart of Calgary’s Cultural District in the downtown core, the centre occupies a full city block and is home to five theatres and the world-class Jack Singer Concert Hall. Recently Sapphire Sound (Calgary) installed a d&b audiotechnik xS-Series point source loudspeaker system in the spectacular and spacious main floor and dress circle lobbies of the Jack Singer Concert Hall, as well as replacing the complete monitor inventory package for the concert hall itself. Sapphire Sound provides state-of-the-art audio and visual services to professional and commercial clients across Western Canada.

The Jack Singer lobby areas can be used in conjunction with the concert hall or as a venue on its own and has hosted such events as Avenue Magazine’s Top 40 Under 40, Canadian Citizenship Ceremony, and The Rozsa Awards. The space is ideal for conferences, galas, receptions, lectures, concerts, meetings, corporate events, post and pre-show events with a capacity of up to 1,000.

“As far as our challenges were concerned, the main section, closest to the hall of the lobby has a 2 ½ story high ceiling, but the rear of the lobby is split into two floors that can sometimes even be hosting separate events simultaneously,” states Jack Jamieson, Head Sound Technician. ‘There are also a lot of glass surfaces throughout the lobby placed for aesthetics that can make it very reflective. To solve this, we used two of the d&b 24S loudspeakers as our primary coverage for the large section, and installed three of the 5S, individually addressable, on each level at the rear of the lobby to allow us to control both the level and the content of the smaller speakers. The large speakers are aimed in and down towards the carpeted lobby floor to avoid unwanted reflections and help isolate the system acoustically from the concert hall. There are also three sets of heavy double doors on each side that are kept closed between the concert hall and the lobby when there is a lobby-only event occurring.”

The dipolar arrangement of the two 12” LF drivers in a 24S, results in directivity control down to 500Hz to keep sound off of walls and other reflective surfaces.

The main floor lobby system is a pair of 24S speakers in stereo, with three 5S speakers each with individual addresses centered under each archway to cover the rear area should that be desired, and three more of the 5S loudspeakers setup the same way to cover the Upper Lobby should that be desired. Each of these eight cabinets has its own channel of amplification, supplied by two D20 amplifiers.

“Arts Commons was initially looking at a d&b V or Y-Series, but I suggested 24S due to the fact that for the majority of events, subwoofers would not be required, and with 24S going all the way down to 55Hz, it would enable relatively full range sound even without the VG SUBs deployed,” added Ben Burrell from Sapphire Sound.

“For the monitor system in the concert hall, the d&b M4 wedge has become the first or second choice product listed on most touring riders that we see,” noted Jamieson. “Accordingly, I had a demo of the product brought in, and all stakeholders agreed that it was one of the best wedge monitors we had ever heard or measured. Further, it was capable of more volume than the largest and loudest cabinet from our previous system, and only ½” wider than our smaller cabinet, and lighter than either of them. It was a unanimous choice from all of us.”

Jamieson said that Arts Commons is extremely happy with the sound of the lobby system both for intelligibility, and for musicality. “Ben is correct about the low frequency capability of the 24S. We have so far only needed to deploy the extra subwoofers twice since installation, and in both cases, it was for EDM style musical content.”

The monitor package for the concert hall includes 17 x d&b M4 monitors, 4 x VG SUBS, 9 x D20 and 2 x D80 amplifiers.
