EV Audio Solution for Bethany College

Osmond Electronics in Adelaide have recently completed the installation of a complete entertainment system into the new performing arts centre at Bethany College in suburban Adelaide. The work involved a complete design and construct resulting in extensive liaising with both architects and builders during all phases of the design and building process. Osmond project manager Kostas Psorakis looked after the project from its inception and was instrumental in ensuring the building incorporated the infrastructure to ensure that an advanced entertainment system could be easily integrated.

The venue has been designed as a performing arts complex to handle everything from contemporary worship on Sundays to school and community theatre and music productions. The venue comprises of a main performance space which includes a balcony that can then be divided off to be utilised as a separate lecture space. In addition there is separate classroom attached that can be used as marshalling and warm-up space. This space as well as the foyer have an incorporated audio and vision system to allow for show relay from the main auditorium.

The Auditorium itself is equipped with a Digico digital audio console that drives a Netmax N8000 matrix controller that incorporates DSP control for the audio system. This includes delay’s for the over balcony speakers that can then be switched to operate in a stand alone mode from a local mixer if required. The N8000 incorporates a TP 12 touch panel adjacent to the mix position that allows for the configuration of the system to be easily changed as required.

The main audio system comprises of an Electro Voice EVA system with a combination of 90 deg long throw cabinets and 120 deg short throw cabinets. There is then attenuation modules fitted to the 120 deg cabinets to ensure an even coverage of the room. The main speaker system is driven by Dynacord Power H amplifiers. In order to control the low frequency in the room Kostas opted for a Cardioid sub array by mounting an Electro Voice XCS 312 cabinet behind each of the mid high hangs processing for these subs is derived from the N8000. A front fill send is also derived from the N8000 that allows for two portable ZXA 1 powered cabinets to be located immediately in front of the stage to cover the front rows and to help lower the audio image.

The over balcony cabinets are EV EVF 1122 cabinets chosen for the cosmetic and sonic similarity to the EVA with both being part of the EV Innovations speaker range. The overbalcony system is controlled via the N8000 Touch Panel to allow for it to be used as a delayed feed from the main system or to be isolated and controlled independently. The balcony area is fitted with a retractable isolation panel system to allow for it to be closed off and utilised as an independent lecture theatre. This then has its own localised control consisting of a Bosch rack mount mixer with a EV wireless microphone system.

One aspect of the system design that has appealed to the college is the dual mode operation set up that has been programmed into the Netmax by Osmond system engineer and technical whizz kid Adam Budgen to allow for the system to be operated in either a fully supervised state from the large digital console at FOH or in a unsupervised state via the simple mixer in the main equipment rack. This is a particularly function for the college staff as it allows a teacher to come in and access the Netmax touchpanel and via the staff access code power the system up with all control routed to the side of stage mixer. Thus for general school assemblies and public meetings a microphone and simple playback can be activated without the need to deal with the complexity of a large mixing console

The venue also incorporates a stage foldback system consisting of EV TX 1122FM wedges being driven from EV CP 2200 power amplifiers providing four sends of monitors. The system also incorporates electro voice microphones with PL series vocal and instrument microphones being used in conjunction with eight channels of REV wireless microphone systems combining both hand held and beltpack transmitters.

The venue is fitted out with Electro Voice EVID ceiling speakers in both the foyer and classroom/rehearsal space area with these drivers being driven by Bosch mixer amplifiers to allow for central paging or localised paging in all areas.

Bethany College have been very happy with the performance and reliability of the system and it has allowed them to provide a high quality experience for both the school and the local community.
