Meyer Sound’s Constellation system installed in Shanghai

0

The Nine Trees Shanghai Future Art Centre in China now features Meyer Sound’s Constellation system. The venue has an organically inspired structure befitting its location in a forest preserve in the city’s Fengxian district. Meyer Sound audio reinforcement systems now feature in the centre’s three theatre spaces, and the largest auditorium also claims the first Constellation active acoustic system in China.

The centre was conceived from the outset as a focal point for a wide spectrum of arts and entertainment performances, hosting both Chinese and international artists representing the global diversity of music, drama and dance.

The project principals surveyed a number of newer theatres in China and overseas, and soon determined that an active acoustic solution would best accommodate the desired diversity of performances. After evaluating available systems, they narrowed their focus to Constellation and initiated consultations with Meyer Sound’s Chinese distributor, Shanghai Broad Future Electro-Technology.

Constellation is installed in the main theatre, which accommodates 1,200 patrons on two levels. The balanced physical room acoustic, with a reverberation time of about 1.2 seconds, can be enhanced with times up to about seven seconds. In addition, the subtle characteristics of the reverberation envelope can be altered by adjusting the warmth, strength and brightness. During commissioning and tuning, 11 presets were created for different performance requirements, with additional presets open for future needs.

The desired acoustical characteristics are created via a total of 160 self-powered, full-range loudspeakers (Ashby-5C, Ashby-8C, UPM-1XP and UPJunior-XP) mounted laterally and overhead, with the lowest octaves reproduced by 16 compact subwoofers (12 UMS-1XPSM and four MM-10XP).

To capture the acoustic ambience, 56 miniature condenser microphones are distributed throughout the space. In between the microphones and loudspeaker output, a D-Mitri digital audio platform comprising 21 modules provides the DSP and matrixing, with five modules – one for each reverberation zone – dedicated to hosting the patented VRAS acoustical algorithm. The theatre’s 30m (98ft)-deep stage is served by a dedicated Constellation zone functioning as a virtual acoustic shell.

For direct sound reinforcement, the main theatre provides a system anchored by dual arrays of 13-unit Leopard line array loudspeakers, with deep bass from four 1100-LFC low frequency control elements. Also deployed as subsystems for fills, delays and foldback are a total of four UPQ-1P, two UPQ-2P, two UPM-1P and 14 MM-4XP loudspeakers along with six MJF-210 stage monitors.

Mounted over the proscenium – concealed behind a scrim – is a left-centre-right system configured with 12 JM-1P and four UPQ-1P loudspeakers for, respectively, far- and near-field coverage. Three Galaxy 816 processors enable system drive and optimisation.

“In addition to the available acoustic presets, we can fine-tune the parameters to suit the needs of the performers,” said Li Yiting, operating technical manager at the theatre. “We conclude that the operation of the system is stable, responsive, naturally reverberating and comfortable sounding. More importantly, you can’t perceive that the reverberation comes from electro-acoustics. The best way to put it is that the applause from the audiences and the response from the performers demonstrate their satisfaction with the system.”

The two smaller venues in the complex are also furnished with Meyer Sound reinforcement systems. The 500-seat multifunctional theatre relies on a system based on 12 Lina line array loudspeakers and six 750-low-frequency control (LFC) elements that can be flown or ground stacked as needed for the event at hand. Completing the system are two UPA-1P loudspeakers, six MJF-210 stage monitors and a Galaxy 816 processor.

The 300-seat theatre is covered by two CAL 64 loudspeakers with advanced beam steering for the main system, augmented by two 750-LFC elements, two UPJ-1P loudspeakers, six MJF-208 stage monitors and a Galaxy 816 processor.
