Helsinki City Theatre Expands Meyer Sound Systems for Total Aural Immersion

Located in Finland’s capital city, the Helsinki City Theatre recently upgraded its Meyer Sound systems for full immersive audio capability, adding dozens of new loudspeakers along with D-Mitri digital audio platforms complete with Wild Tracks multichannel playback and Space Map 3D panning.

The system in the 947-seat Big Stage was expanded to a total of 124 Meyer Sound self-powered loudspeakers while an appropriately scaled-down system of almost 50 loudspeakers was deployed for the 347 seat Small Stage.

This major new investment in audio technology reflects a commitment on the part of Helsinki City Theatre to stay on the cutting edge of sound design, whether for drama, Broadway-style musicals or experimental theatre.

“Theatre is a laboratory where you should try new innovations,” observed Eradj Nazimov, Helsinki City Theatre’s staff sound designer. “There is no right way or wrong way, as each show is new and different. Certainly this new investment expands the boundaries of what we can accomplish with sound.”

All 124 loudspeakers in the Big Stage system are individually addressable through dedicated outputs of the D-Mitri processors, allowing unprecedented control for creating immersive effects using Meyer Sound’s Space Map 3D panning software. This capability allows simultaneous, dynamic movement of multiple sounds anywhere in the theatre.

At the same time, the new installation does not compromise on the fundamentals of contemporary theatrical sound. The main proscenium system employs the Broadway-standard A/B configuration, used by the theatre for decades, with two completely separate speaker systems to keep summing of signals in the acoustical domain. “The result is a much clearer and richer sound image,” explained Eradj.

The primary system for the Big Stage is anchored by 18 UPQ-1P loudspeakers with bass reinforcement from three 900-LFC low frequency control elements (flown as a cardioid array) and one 1100-LFC element. The immersive surround system comprises 68 full-range Meyer Sound loudspeakers (28 UPJ-1P, 32 UPM-1P, 4 CQ-1, and 10 UP-4XP) plus four USW-1P subwoofers.

Design of the system was accomplished over a two year period, with Granlund Consulting’s Jan Holm collaborating with Eradj and system integrator Studiotec of Helsinki. In the early stages of the project, Meyer Sound Director of System Optimisation, Bob McCarthy, also contributed to the design.

Meyer Sound systems have been in continuous use at Helsinki City Theatre since 1986, when a complement of UPA-1 loudspeakers were brought in for an extended run of the musical Cats. “Product longevity and outstanding support are critical for theatre and these are two of the reasons we chose Meyer Sound,” said Eradj. He added that he is equally impressed with the linearity and freedom from distortion exhibited across the Meyer Sound product line.

A number of loudspeakers taken from the Big Stage have been repurposed to enable an expanded, immersive sound capability in the Small Stage auditorium. Assisting in design for this venue was Josè Gaudin, European technical support specialist at Meyer Sound.

“Meyer Sound offers unbeatable cost-effectiveness when you look at purchases over the long term,” said Antti Murto, sales manager at Studiotec. “You find that you don’t have to renew the entire system with all new loudspeakers with each major renovation.”

Now equipped with what is quite likely the largest point-source distributed theatre system in northern Europe, Helsinki City Theatre is prepared to offer both local and touring productions the latest in high quality, immersive sound technology.

“When you’re building such a large and complex system, it certainly helps to take advantage of all the experience and expertise available,” concluded sound designer Eradj. “We had almost daily meetings with Studiotec and the feedback was constructive on both sides. We had the opportunity to get the tools we wanted, and the results have been all that we had hoped for.”

The Helsinki City Theatre stages about 20 new productions annually with a total of over 1,000 performances on six stages. The theatre’s current building was completed in 1967 and expanded with an annex in 1989.
