Half Round Church

This system design template describes a typical loudspeaker layout for half-round or half-octagon room. In this format, the congregation seating wraps around and focuses on  the platform creating a more intimate and communal environment in a larger space.

Room design

Align the loudspeakers with the presenter's position (podium, pulpit, stage, etc.), and address each seating area independently. Choose the appropriate coverage pattern and proper location to minimize overlapping effects in adjacent speaker zones.

In many cases, medium format two-way I SERIES models and three-way V SERIES models offer a wide range of choices to suit these requirements. In bigger versions of this venue, IP8-1153 three-way loudspeakers can be used to cover the larger seating areas. The smaller seating areas on the sides may need slightly different loudspeaker models that are similarly voiced.

Subwoofers can be added to provide extra bass support.

Amplified Loudspeaker Controllers 

Biamp's line of Community Amplified Loudspeaker Controllers (ALC) offers 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.
