音乐厅实现集中控制

在过去的10年中， {Perth Concert Hall in Scotland}举办过不同形式的活动，包括音乐会、演出、当代艺术表演、政治会议和企业活动。在那时，繁忙的技术团队自然必须适应不断变化的客户需求和日新月异的技术。场馆内部署了各种不同的音视频系统，其中许多系统无法相互通信。客户的要求是整合所有系统（传统设备和新设备）。“这个音乐厅里有七个不同的音响系统，还有许多不同的照明控制系统。光是在一个房间内打开声音和视频的功能就已经是一项艰巨的任务，而现在，我们可以在iPad上实现。”珀斯音乐厅制作和技术经理Patrick Dalgety说道。集成商Autographsales & Installations的作用就体现在这一方面。

At the heart of the new install was the decision to go with QSC’s Q-SYS Designer software.

Walking into the foyer the visitor is immediately struck by Scotland’s largest dedicated digital art installation. The foyer displays show a mix of art and advertising (promoting future events) and is fully programmable and linked to a central calendar which controls all the lighting and sound. The busiest room in the venue is the Norie-Miller Suite. The room can accommodate 120 people, or be split into two (for 50 or 60 people), and is home to workshops, music shows and AGMs. AV in here is controlled by panels in the wall. If the team needs to split the room a single button press will instruct Q-SYS the room is now in two. Depending on which code the operator enters into the panel, the operator can access different levels of control. For those events where the tech team needs a bit more control, the consultant specified JLCooper control surfaces, which take command of visuals, light and sound from one custom board. “This is one of the more custom pieces of this project,” says Chris Austin, technical sales manager, Autograph. “The JLCooper control surfaces came as a completely blank canvas, so we had to write our own integration into Q-SYS for that.”

The level of control the tech team now has with Q-SYS has obviously made a huge difference to their working lives, as Dalgety demonstrates: “All the Shure radio mics can be used anywhere in the building. You just go to the space you want and select the mic you want and that setup will come out in the right space. The inclusion of the automixer means we have presets.”

It’s not a small task managing what’s going on, as around the venue there are 130 channels running on Q-SYS, with around 60 running on Dante. Austin estimates there are around 200 channels of audio on the network in total, running at a continuous 300Mb/s, ‘it’s a heavily trafficked network,’ he adds.

Upstairs at the Concert Hall are more conference rooms, with the 16-seatre Tay Boardroom. Again, due to the flexibility of the space, Q-SYS has been programmed to reflect this; “Every morning at 4am everything gets set back to default. So the staff coming in first thing in the morning have consistency,” says Dalgety.
 

The benefits of the new technology are clear says Dalgety, “We have a faster turnaround, and fault-finding is easier.

“The scale of the network and the resilience required was quite a challenge,” continues Austin. “If it was a closed shop and we had total control of the network, it would be quite straightforward. The challenge here is I can’t control who is going to plug something in and where they are going to plug it. If a visiting engineer comes here with a Dante-enabled sound desk it’s fair game for them to plug it into the network.”
