Integrator TEDAV has installed a plug-and-play system in Springfield Community Centre on the campus in Corsham. Commissioned by Wiltshire council, TEDAV integrated all the communications and audiovisual, incorporating protocols common to the Harman Pro components.

With support from Harman distributor Sound Technology, project manager Gee Edwards designed a network to enable the dance studio to either take audio feeds from the main room or operate autonomously. “I don’t think anyone has wired such a stand-alone system as this, as we’ve managed to take all the audio from the AV, including the HDMI/VGA audio, and the AKG WMS470 radio mics into the Soundweb BLU-100 (12-in/8-out) DSP so you don’t necessarily need a mixer.”

Two AKG WMS-470 D5 handheld mics are designated for each space (one pair in the mobile rack in the dance studio wired back to the receivers into the main room) outputting to JBL CBT constant beam width column speakers.

Since the building framework is timber construction, weight loading was an issue and so in the main room TEDAV has specified two JBL CBT70JE (along with a pair of JBL PRX412 for monitoring) and a pair of CBT100LA in the second room. The power is provided from three Crown XTi 2002 amplifiers.

“The CBT technology provides a clear and punchy sound,” confirmed Edwards. “The CBT100LA contains 16 very small horns to get clarity in what is a cavernous space.”

“In the main room the CBT70JE was a perfect choice as we couldn’t fly anything from the ceiling and had to hang them from the lighting bars. We needed to go with a lightweight option, and since there was nowhere to mount the subs in view of the sprung floor, the CBT70JE sub extender also worked well. It’s ideal for day-to-day use, with good SPL, delivering great bottom end, and speech reproduction. We only needed one on each side of a room measuring 14m x 18m and these are situated 4m from the front wall. Finally, because the 70JE is directional and ellipsoidal the bounce is kept to a minimum.”

Video projection (3LCD, 13000 ANSI lumens) with source switching and provision of colour-changing LED profiles and fresnels complete the installation.

Gee Edwards concluded: “All the I/Os in Soundweb are being used and it’s easy for them to use in basic or digital mode.

“In addition, we have provided three facility panels, each with BLU-Link and MADI and they can patch over Cat6 cable via Neutrik EtherCON. We have also provided them with some redundancy.”
