In recent years, China has vigorously developed the cultural industry, the construction of theaters are included. This provides people with a place for leisure and entertainment, and enhances the quality and spiritual culture of the nation. Therefore, Rrapro decides to carry out a series of review of grand theaters to unveil the mystery of them. Here, we will start with the National Centre for the Performing Arts of China.
National Centre for the Performing Arts of China
At the beginning of April, the NCPA announced that it would hold online concerts every Saturday night until the venue officially resumes performances. The NCPA orchestra performers would present a series of online concerts with the themes of "Late Spring", "Echoes of Destiny", "Blessings of Love” and “Embrace of Spring" at the Master Club. After the first online concert, many music lovers have expressed that they are eager to be on the site and hope the NCPA could resume operation soon.
The NCPA is a landmark building, one of the new "Sixteen Views of Beijing", located in the west of Tian’anmen Square and the west of the Great Hall of the People, consisting the main building, the underwater promenade on the north and south sides, underground parking, artificial lake and green areas.
Three Profession Theaters and One Multi-Function Theater
There are three theaters in the GT, namely the Opera House, the Concert Hall and the Drama House, which are completely independent but provide sky lobbies that you can walk through all. The theater enjoys a luxury design, decorated more than 20 different kinds of red color, making the silk laying area reaching 4,000 square meters on the wall, and all these come from a famous France painter, Alain Bonny.
Opera House
The Opera House is the grandest building in the NCPA, with a gorgeous golden as its main color. The auditorium of the opera house is equipped with one stalls and three balconies that can be occupied with 2207 people (including standing-room). Opera, dance drama, ballet and large-scale arts performances are mainly presented.
Control Room
Since the audio system of NCPA put into use, the control part of consoles gradually get aged and damaged. To ensure the audio system goes professionally and stably during performance, console mixing system has been renovated and upgraded. Now, we come with the DiGiCo consoles from England.
Main Console: DiGiCo SD7T
Mobile Console: DiGiCo SD5
Stage Boxes: SD-Rack & SD-Mini Rack
The console connected with stage box forms an optic loop where the input and output of each signal can be shared with each other. Regardless of the problem at any endpoint, the devices still function normally.
Drama House
With Chinese red tone-based, drama House in NCPA is with the most national features, traditional and passionate. Drama, opera and local opera are mainly presented, and it can accomodate 957 people at the same time.
DiGiCo SD7T
Same with the opera house, the drama house has been renovated and upgraded with DiGiCo SD7T as the main PA console, whose stability and functionality can guarantee the performance goes well.
Concert Hall
The concert hall is painted with pure white, making it looks fresh and elegant. Concert hall mainly presents large-scale symphonic and folk music, as well as other forms of musical performanc.
The stage of concert hall is in the certer surrounded by 462 seats for stalls, there are more 880 seats for first balcony and 517 seats for second balcony, 1859 seats in total. The concert hall owns the biggest pipe organ in domestic, which could be “the treasure of the hall”.
To achieve the best result, all architectural and decorative design in the concert hall are matched with the acoustical effect, the originator of the line source array, L-Acoustics is chosen.
Main System: dV-DOSC
Subwoofer: dV-SUB和SB218
Fill System: ARCS
Stage Monitor: 115XT HiQ
NCPA Taihu Stage Art Center
With more performance gaining in NCPA, tight rehearsal schedules, lack of stage design and insufficient storing room, etc., has occurred. To solve this, NCPA Taihu Stage Art Center is officially under construction, located in Taihu Town, Tongzhou District.
Rehearsal Theater
Taihu Stage Art Center covers a building area of 59,700 m2, as the main performance venue, rehearsal theater is equipped with 838 seats, and its forestage is same as the NCPA opera house’s, this is helping the performers to adjsust themselves during rehearsal as if they were in opera house, that’s why Taihu Stage Art Center can be called the “Back-up” of NCPA.
Based on the needs of the venue, the speakers for theater are used in LCR design. The main system adapts L-Acoustics Kiva II line source array plus SB15m subs placed on both sides. Kiva II is designed for medium and long distance application, with bandwidth between 70 Hz and 20 kHz. Thanks to the powerful performance of the speaker units, the Kiva II has excellent SPL with a maximum level of 138 dB.
Kiva II is also chosen for central system & in fill system, with horizontal directivity pattern: 100°, guaranteeing a great coverage for the audience.
X8 is used for the orchestra, whose coaxial design provides a wide conical directivity, with excellent spatial resolution and no minimum listening distance, perfect for the orchestra. In addition, the X8 is also used as a surround effect speaker, audience can enjoy the music with no limit.
For stage monitor, 12XTi and X15HiQ coaxial speakers are used as the stage intalled stage monitor and mobile stage monitor.
Kiva II is also used as the central system, with SB18i on each side, perfectly extending the LF.
The whole system amplified by LA4X and LA12X. LA4X is a highly efficient Class D amplifier controller equipped with green energy-saving technology and SMPS power supply with PFC, providing 4x1000 W. While LA12X could be more powerful, providing 4x3300 W.
Mixing console plays a central role in the sound reinforcement system, and rehearsal theater choses DiGiCo SD7T to enhance the sound performance.
SD7T's T is another version for theater, which updated with more functions in terms of application that suitable for theater use. Powerful FPGA technology, 253 maximum input processing channels, 128 maximum aux/sub-editor bus and WavesV9/8/7 effects plug-in function supported, promoting SD7T owns a powerful production capabilities. What’s more, its high processing power coupled with dual-engine features, making it can be mirrorred to maintain the stability of the performance.
L-Acoustics works with DiGiCo, to create a world-class venue for reheasaltheater
