Nexo-Yamaha networked system specified for new arts centre

A fully integrated and networked Nexo-Yamaha theatre sound system has been installed in the Westa Kawagoe centre, a new multipurpose venue in Kawagoe City, just outside Tokyo.

The system, under full digital control, has both fixed and portable elements and features GEO S12 and STM Series line array and Alpha and PS Series point-source loudspeaker systems, with Yamaha CL5 and QL1 digital consoles, installed by Yamaha Sound Systems.

The centre’s Main Hall has approximately 1,700 seats and is able to support a range of concerts, theatre and other performing arts programmes.

The main speaker system uses the Nexo GEO S12 system of line array speakers, flown on the sides and the Alpha system of Hi-Q point source speakers in the proscenium. The system is designed so that the side and proscenium speaker systems work independently to cover the entire hall. The side speakers, which are mainly used for musical reproduction and other entertainment applications, can also be housed in the proscenium arch.

To streamline installation, the Westa Kawagoe is equipped with mechanisms to raise and lower the arrays, which optimises the acoustic environment and ensures a high level of clarity. Each system is driven by NXAMP4x4 amplifiers with built-in DSPs from Nexo.

Nexo’s STM-M28 two-way full-range Omni Module speakers from the flagship STM series were used for the movable stage speakers. The configuration includes an added STM-S118 sub module for the sub-bass range together with an STM-B112 bass module, enabling powerful sound output while having a compact appearance.

The main mixing console is a Yamaha CL5 with the QL1 console included in the mixing consoles in the stage wings. Dante audio networking was adopted for the control room, the amplifier rooms, and for sound transfer to and from the stage. Every piece of equipment is tied into the network, simplifying the physical wiring layout, and this configuration also allows centralised management for monitoring and control of each piece of equipment in the audio control room, on the stage, and in the power amplifier rooms.
