Old Barn Audio selects Martin Audio CDDs for ice rink install

Lee Valley Ice Centre in Leytonstone, London has upgraded its sound system with a Martin Audio CDD system installed by Old Barn Audio (OBA) to provide even coverage within its existing infrastructure.

Previously OBA, a Martin Audio partner, completed a similar sound system upgrade using the CDD range at the £31m Lee Valley White Water Centre in Waltham Cross, one of the host venues for the 2012 London Olympics.

The 15-year-old system in Lee Valley Ice Centre was starting to fail and parts were no longer available. Chris Bailey, technical manager Lee Valley Leisure Trust, said: “Based on the performance of CDD at White Water I requested the Martin Audio CDD speakers again but being a bigger venue it needed a more powerful solution.

“I had listened to the MLA Compact subs when OBA’s touring system was brought in for the ICF Canoe Slalom World Championships at Whitewater, and they told me that the CSX subs were voiced similarly. So based on the performance of the CDD10 with the companion CSX subs I knew Martin Audio was the way to go.”

OBA directors Phil Clark and Neil Kavanagh created a cost-effective design that would enable them to work with the existing infrastructure. This would not only mitigate the pre-existing ‘spill’, but focus the sound over the rink while providing even coverage to the perimeter seating on all four axes.

The central roof truss houses a standard cube, which displays digital scoring and timing, and also scrolls messages. Underneath is a circular truss to which OBA has fitted four CDD10 (10in) loudspeakers. This is flanked by two further aluminium truss bars, fixed to the roof, and each supports twin CDD12 (12in) and twin CSX118F (18in sub) via the Martin Audio flying yokes.

“The whole system has been phase aligned, time aligned and EQ’d so it is seamless, although we could virtually run it straight out of the box,” said Phil Clark. “The old system had delivered a lot of echo but we were able to tweak this using SMAART acoustic measurement.”

Programming is within a Symetrix DSP environment using the Martin Audio data files, and wall panels provide multiple source select across the seven zones; this not only includes the bowl but also the upstairs private Valley Bar with a further four CDD8s (8in).

The Ice Centre uses PRS-licensed streaming service company, Ambie Media, who curate the playlists and provide constant bit rate streaming of 192kbps over the internet.

Ice hockey commentaries are delivered from the main rink-side Technical Area, and while hosting international skaters, there is also an ice-side music station to enable elite skaters to bring their own MP3s.

Meanwhile, in peripheral areas such as the café a button mic will also read ambient noise levels and auto sensors will raise the volume levels of the music accordingly.

Main Reception is also where the new master PA-VA paging control is found, with 16 pre-recorded cascading messages with evacuation/fire alarm protocols. The touchscreen computer panel is alerted via the bespoke MP3 trigger system designed by OBA, feeding serial ports in the DSP. Other than Reception, further paging stations are located in the rink-side Control Booth and Managers Office.

Clark stated: “CDD delivers a lot of bang for the buck, and the system here has been entirely tailored to the venue. We are honoured to have become part of the Lee Valley procurement team and proud to have carried out our second CDD installation for them in six months using Martin Audio’s flagship product.”

Chris Bailey concluded: “The CDD installation has made a massive difference. The intelligibility is now fantastic and the frequency response and dynamic range of the music is now so much better.

“It has greatly enhanced the user experience and given us one of the best sounding systems at any ice rink in the UK.”
