School Auditorium
This system design template describes a typical loudspeaker system for a school auditorium. This dedicated performance space may need to cater to a wide range of events.
Room design
Two (mirror image) arrays cover the entire space providing 'stereo' sound. Each consist of a dual two-way horizontal array for optimum coverage. Equipment recommendations for an alternate Center array are also shown for a centrally consolidated array to cover the full audience area from a center hang position.
For music events, the wide imaging of a Left/Right “stereo” array offers spatial advantages while lecture events are best reinforced by a centrally oriented array. Theatrical events benefit from the imaging capabilities of both, however sight line considerations may dictate one or the other. Ideally these spaces benefit from a true Left/Center/Right layout. Each array must fully address all seating areas. Each portion is addressed separately from the mixing console to allow the mix operator to direct stereo, monaural, or specially panned signals to each array to best support the presentation. It is more important to follow the seating lines and stage width to configure the array for coherent coverage. In some cases single L/R loudspeakers can provide sufficient coverage, but in many cases a pair is needed on both sides to provide enough horizontal coverage.
Equipment list
Below is the list of Community equipment used in this design:
Left/Right Coverage design:
- 4 - Community IP8-1152 High Power 15-inch Two-Way Installation Loudspeaker; 30 Hz – 22.4 kHz, (H x V): /26 (120° x 60°), /64 (60° x 40°), /66 (60°x 60°), /94 (90° x 40°), /96 (90° x 60°), /99 (90° x 90°)
- 1 - Community ALC-3202D Amplified Loudspeaker Controller: 2 Channels x 3200W + DSP and Dante
- 2 - Community HSB-BFR22 BalancePoint™ Dual Horizontal Splay Two-Way vertical
Center Array design(optional):
- 3 - Community IP8-1152 High Power 15-inch Two-Way Installation Loudspeaker; 30 Hz – 22.4 kHz, (H x V): /26 (120° x 60°), /64 (60° x 40°), /66 (60°x 60°), /94 (90° x 40°), /96 (90° x 60°), /99 (90° x 90°)
- 1 - Community ALC-3202D Amplified Loudspeaker Controller: 2 Channels x 3200W + DSP and Dante
- 3- Community IVY1153B/W Vertical yoke for IP-1153 (Black/White)
- 1 - Community IAF40 BalancePoint™ Isometric Array Frames on (requires U-Brackets or Vertical Yokes)
Subwoofer (optional):
When possible, distributing subwoofers across the front of the stage offers even coverage, but mounting them overhead can preserve floor space.
Amplified Loudspeaker Controllers
Biamp's line of Community Amplified Loudspeaker Controllers (ALC) are the recommended amplifiers for this application. They offer factory-optimized DSP processing, protective limiting and amplification, as well as signal routing, zone switching, and remote monitoring for virtually any Community loudspeaker application.
Standard Ethernet communication protocols allow for fast system design, system control, and remote system monitoring. Analog and Dante® inputs included in each model are assignable per channel in static or failover/backup configuration, supporting quick and easy integration into any new or existing system.
Community-authored loudspeaker presets include equalization, high pass filters, and multi-stage limiters tailored to each model, ensuring consistent sound quality and full loudspeaker protection in every application. Additionally, each Community loudspeaker preset includes loudspeaker power and impedance information, allowing the system configuration software to display the total power and impedance of multiple parallel wired loudspeakers, further reducing the time and effort required to match complete loudspeaker systems with the appropriate ALC models and output channel configurations.
In-depth control and monitoring is accomplished via ArmoníaPlus® system manager software.
