This system design template describes a typical loudspeaker system design for an auditorium with a raised stage and tiered sectional seating. This is primarily a lecture space. It may also host a wide range of activities, including presentations or entertainment events, when it must deliver full-bandwidth audio. It has a raised stage and lower front ceiling necessitating low profile loudspeaker solutions.
The design will center around an exploded mono cluster. Each array will cover a section of seating with subwoofers mounted behind in landscape orientation. Multiple power handling and horn pattern options are available to fit specific needs of the designed space.
An exploded array of horizontally oriented medium-format loudspeakers covers each section (Left/Center/Right [LCR]), and in this case subwoofers are mounted behind for full low frequency support. Depending upon the ceiling heights and the depth of the room, the space may be better served with two sets of arrayed loudspeakers (similar to Distributed Source configuration on the Lecture Hall, next page), with one set covering the front half of the seating and another placed about halfway back addressing the upper audience. Additional stereo loudspeakers can be included to support LCR type events or occasional cinema use.
Unless this space is exclusively used for lectures, subwoofers are needed. Due to limited floor space, they can be mounted overhead (as shown). For a deeper bass impact and more even bass coverage, array compact subwoofers along, or concealed in, the down-stage face of the stage.
Below is the list of Community equipment used in this design:

- 3 - Community IS8-212 High Power Dual 12-inch Subwoofer; 38 Hz – 140 Hz, (H x V): 360° x 180°
- 3 - Community SBR54 Subwoofer Behind BalancePoint™ Fly Rails
- 2 - Community ALC-1604D Amplified Loudspeaker Controller: 4 Channels x 1600W + DSP and Dante
Suggested model families: I SERIES (IP600/800, IS600/800) and V SERIES (V2-6, V2-26, V2-8, V2-28, V2-32, V2-35, VLF208LV)
Additional Subwoofers (optional): Spaced across the front of the stage area for extra bass support of cinema or musical events.
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.
