Ruhrtriennale Yamaha

Sound engineer Norbert Ommer, responsible for audio production, has chosen the digital mixing system Yamaha Rivage PM10 for the opera Bählamms Fest.

Founded in 2012, Ruhrtriennale is a triennial cycle of musical and artistic events held from August to October in the German industrial region of the Ruhr; a unique festival encompassing a wide range of performances, all of them in places created within the industrial architecture of the region.

For each cycle, a new artistic director is appointed. For the period 2021-2023 is the renowned German theatre producer and director Barbara Frey, who has inaugurated the program with the surrealist opera Bählamms Fest, based on the play The Feast of the Lambs, by Leonora Carrington.

Ruhrtriennale YamahaThis production of Ensemble Modern, a world-renowned collective of soloists, has again had the sound designer Norbert Ommer, who has chosen the Yamaha Rivage PM10 digital mixing system for Bählamms Fest.

Ommer was one of the first sound engineers to use the digital mixer Yamaha PM1D for classic productions, with a high number of inputs and outputs.

“This production of Bählamms Fest it has not been a traditional opera, explains Ommer.. Una parte esencial de la composición era la alimentación de múltiples sonidos y la comunicación de sentimientos de alienación”.

For this project “utilizamos un software del Instituto de Investigación y Coordinación Acústica/Musical (IRCAM) to transform the sounds of singers. On four Macintosh laptops, voices were analyzed to find the fundamental frequency or pitch, to later play a pre-recorded sound based on the detected tone In addition, the orchestra was located in a pit, sino en una parte de la zona de montaje que daba la espalda al público”, Says.

Ruhrtriennale YamahaThis expert's sound design has been crucial, not only to turn the Jahrhunderthalle congress centre into the acoustic equivalent of an opera house, but to get the sound of the orchestra to fill the entire auditorium and, as underlined, “envolviera las voces cantantes”.

To achieve this, he designed a system with 124 microphone inputs, mixed in the I/O rack Yamaha Rivage PM10 with conversion RMio64-D Dante/MADI, routed to 44 Outputs, Including 12 surround sound channels Ambisonics.

La idea básica del diseño de sonido se basaba en el L-C-R principle -explains-, but I used different provisions, each of which represented different sources of sound and was arranged according to the law of the first wavefront., or Haas effect“.

For this design, Ommer also used ‘effect systems’ en el escenariocon el fin de ampliar su espacio sonoro, so to speak, mientras el público estaba rodeado adicionalmente por dieciséis fuentes para crear una espacialidad multicanal en el auditorio”.

The choice of Yamaha Rivage PM10 responded to the need for a fast and reliable system, with a large number of channels. “Quería un sistema de mezcla que me ofreciera una gran claridad y calidad de sonido, many inputs and outputs and, above all, simple operation. I work alone and read the score while mixing the performance, y necesitaba un acceso muy rápido a todos los parámetros y también ofrecía la máxima fiabilidad de funcionamiento”.

Otro elemento importante de este equipo han sidolos preamplificadores, that can be controlled very precisely; something very important for opera singers with its high dynamic range. It also has great sound filters, que no lo colorean cuando se utilizan con instrumentos y voces clásicas”, Adds.

The production has been a success, “en el que muchas críticas destacaban la gran calidad del sonido y la claridad de las voces -recalca Norbert-. The Ensemble Modern and the conductor Sylvain Cambreling quedaron sorprendidos tanto por la belleza del sonido como por el perfecto funcionamiento del sistema”.
