This major renovation meant enlarging the entire auditorium, refurbing the music department and adding some additional rehearsal spaces. Working along with the architects, our plan was to include electronic acoustics in many locations. It would not only be the in the auditorium and on the stage, but also in the large rehearsal rooms for orchestra, band and choral ensembles. Singers and musicians would then be able to rehearse in environments similar to what they would experience in the auditorium. That became the initial driving force for the acoustical design. We had to look at how to treat the main auditorium to get the reverb time low enough and flat enough that when we implement the electronic acoustics, there will not be significant problems with frequency balance and reverberation curves. The electronic acoustics system is based on Yamaha acoustic field correction devices. It is implemented with speakers located onstage, in overhead ceilings, in under-balcony ceilings, and on sidewalls. These systems are providing reverberation as well as early reflection support for the room. The system can also add voice lift to allow for events without sound reinforcement. The auditorium was being dramatically enlarged, shaped with curved walls plus adding a balcony. To deal with that condition we developed a custom absorptive diffusive wall treatment. It consists of series of wells of different depths with perforated materials and solid materials, creating a diffuse sound field within the auditorium and generating a relatively low reverberation time for the size of the room. This design criteria was also used for the music spaces to produce similar reverberation curves for their base conditions. That way, when the electronic systems are commissioned, there will be tunings for each space that will mimic each other to the degree that you can mimic a smaller space to a larger space. In addition to the electronic acoustics and physical acoustic designs for this auditorium, AVL Designs Inc. was contracted for stage rigging, theatrical and house lighting, and sound and video in the space. One of the unusual features of the room is the incorporation of Danley Jericho loudspeakers. The Jerichos look huge and indeed are huge, but they are actually a replacement for line array technology that many auditoriums would implement, at a lower cost and a higher performance level. The Jericho combines a large number of drivers in a single large enclosure, creating an output pattern and sound pressure capability similar to a 12 element tall, mid to large scale line array. Admittedly, it looks a little odd to have boxes this big in a high school auditorium however the pattern control over the wide frequency range of the speaker allows it to cover most of the main floor as well as the balcony without the need for other devices. We also installed over and under-balcony delay fill speakers. This was primarily for potential special effects for theater use, and also to add the few frequencies that would be missing as you go by distance to the back of the room. The audio system is fitted with an Allen and Heath D Live console, which is a substitute for a Yamaha console originally specified. (Due to Covid issues the Yamaha console is not currently available) The D Live is a great console and will do a fantastic job for the school in the new application. Theatrical lighting consists primarily of Electronic Theater Control products and High End systems, with some Strand and Phillips fixtures as well. Stage rigging is a combination of Brick House counterweights and Electronic Theater Controls Prodigy hoists. The Prodigy hoists are used for onstage electrics, as well as a front of house moving head electric. All of the music rooms are used as green rooms, so we have a combination of intercom, call lights, and video feeds to each of those spaces from the main auditorium. The transformation from the original room to what it is now is dramatic.
