The audio racks at the Anzu Hall Cultural Centre.
Japan - The 1,300-capacity Anzu Hall Cultural Centre in Koshoku City has undergone a dynamic sound system refurbishment based around a QSC network and monitoring system. The multi-purpose Anzu Hall - situated inside the City Hall complex - hosts a wide variety of cultural events. Ueda JRC carried out the installation, supported by ComodoMattina Inc, QSC’s Japanese distributor. The company’s Takafumi Asahina says: "Originally, the client didn’t have a clear idea of what they wanted, and so we recommended QSC’s QSControl (pronounced Q’s Control) network audio control solution as being the most progressive way forward."

The QSControl remote management system, a RAVE Ethernet-based signal transport design, and CX Series amplifiers form the hub of the project. With four of QSC’s new ISIS 102W loudspeakers also commissioned for the task of surround sound chores, the audio revamp has been dominated by the California company’s equipment.

QSC’s ISIS loudspeaker product line is a series of full-range, portable, multipurpose enclosures. The 102W features a 10" LF driver, a 1.4" exit, 3" titanium diaphragm compression driver, and a high-power ferrite woofer for maximum output. The 102W also features an advanced rotatable 150° x 50° waveguide to achieve the widest possible coverage area.

The control building blocks for ComodoMattina’s design comprised 21 CX702 and four CX302 two-channel amplifiers, as well as a CX404 four-channel amp - all incorporating QSC's PowerWave technology. The venue uses two RAVE188s-24s, members of QSC’s digital audio transport system, providing eight input and output channels of 24-bit/48kHz A/D and D/A, and utilized between the side of the stage and the mixing room.

Since CAT5 cables have been run into the office area, lobby area, and an adjacent small hall, the RAVE188s-24 can receive and send the audio to and from each location, via industry-standard RJ-45 connectors that provide a secure and robust connection for Ethernet-based networks. According to QSC, the staff at the Anzu Hall is delighted with the newly commissioned system, which has given them greater flexibility, cleaner audio signals, and has extended the functionality of their sound system.
