Singapore (September 17, 2014)—The new Singapore Sports Hub has now opened on the site of Singapore’s former National Stadium in Kallang, with a sound system powered by Powersoft amplifiers.
Construction of the 55,000-capacity stadium began in 2011; in 2012, Electronics & Engineering Pte (E&E) won the contract for the full integration of the Event Sound System and HD giant screens. Working to an architectural and engineering design prepared by the consultants, they specified more than 130 Powersoft 1U K-Series and Duecanali Series amplifiers to drive the various PA and sound reinforcement systems.
The network design for the National Stadium audio transmission is complex, involving switching via 40 Netgear Gigabit 1000 base network switches. The main racks hold 70 Powersoft K10 amplifiers and 26 K2 amplifiers, incorporating the company’s proprietary DSP+AESOP technology.
These are found in 16 air-conditioned racks up on the Catwalk where they power six EAW MQX speakers, 35 QX speakers and 48 SB528zP subwoofers to serve the entire stadium bowl, processed by Symetrix SymNet Edge DSP, while a PC runs Dante software control and patching.
Elsewhere, a similar network was constructed for the OCBC Arena, using Powersoft’s Duecanali 2-channel installation series. Via Netgear 1000 base network switching, in Amp Room 1, 22 Powersoft Duecanali D3904 amplifiers were specified to power large quantities of EAW and Community loudspeakers at various levels in all six halls — with signal processing again carried out in SymNet Edge, with signal transport over Dante.
The final deployment of Powersoft amplification is in the Water Sports Centre, which, like the other zones, is fully featured with Netgear switching, Symnet DSP, full audio control/mixing and playback devices. Here, the final three Powersoft Duecanali D3904 can be found in the Amp Room, driving three EAW speakers installed at the top tower of the Centre.
