「音樂非常好聽，但更我驚奇的是現場的 PA 系統，這絕對是我聽過最好的戶外音響系統。」

「這場歌劇的樂團伴奏與歌手演唱皆是現場演出，混音之後透過 PA 系統播放。歌手的歌唱與口白經過麥克風收音與放大，效果仍然非常好，清晰無比，遠勝許多演唱會現場。樂團的部份更是精彩，在故宮山腰如此空曠的環境，戶外強放，音質卻有 hi-fi 系統的水準，打破了過去我對 PA 的不良印象。以前參加戶外音樂會或演唱會等現場，聽到粗糙轟雜的音樂重播，並非 PA 喇叭的天限，其實 PA 喇叭的聲音也是可以非常傳真細緻的。」

Project Information

This project set its history scenes in the National Palace Museum which conforms to the condition of cultural memory of the Site-Specific Theater. The background of the story in the early 18th century, the scriptwriter give us a image at the beginning in the era of the great exploration on the ocean. The Sino-Franco friendship is established between Emperor Kangxi and Louis XIV in mutual unfamiliarity and curiosity.

The opera has 26 theme tunes, among which 18 belong to the Chinese portion, 7 belong to the French portion and 1 is of the Sino-Franco portion. All these music play by a 30 people symphony orchestra and a 10 people traditional Chinese band. It’s hard to keep the balance between opera signer and the symphony orchestra; and between Peking opera signer and the traditional Chinese band, and also when these four parts comes together.

When I designed the FOH system for the Palace Museum outdoor plaza, I found there have no chance to set up the FOH speakers in front of the main stage(stage B), I put them on the top stage level(stage A and orchestra platform) the bottom box have 10m vertical distance from the audience. Therefore I add 4 speaker under the main stage for the delay front fill.

The first idea is quite simple channels to Stereo, Stereo to Matrix and Matrix to each speakers. After the sound check I realized that it’s not that simple as I though, the same source to speaker at different altitude will cause the actor confuse by the delay voice behind them when they are on stage B even they still can heard the monitor.

I give up the original plan I took, luckily my mixing console can send the channels directly to Matrix just like send to Aux, let me can have different balance between vocal and band in every sets of speakers. It spend me a morning to get the perfect balance, the result is about vocal 25% and band 70% in the FOH speakers, vocal 60% and band 40% in the front fill speakers. Side area speaker and the screen delay speaker down stairs still keep the channels to Stereo balance.
