Community ALC Action
Community Professional Loudspeakers launches its new line of Amplified Loudspeaker Controllers (ALC) at InfoComm 2019. The line will be on display at booth #6343 and on demonstration in Demo Room #W224E.
The new Amplified Loudspeaker Controllers are designed to provide all of the signal routing, zone switching, DSP processing, protective limiting, remote monitoring, and amplification functions needed between a mixer and the loudspeakers in 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.
Carefully chosen to precisely match the needs of all Community loudspeakers, three models of Amplified Loudspeaker Controllers are available: ALC-404D (4 channels x 400W), the ALC-1604D (4 channels x 1600W), and the ALC-3202D (2 channels x 3200W). Bridged channel pairs support driving loads down to 4 ohms at double the power of a single channel, providing additional flexibility for real-world Community loudspeaker system applications.
Community-authored loudspeaker presets include equalisation, 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.
ALC’s reduce complexity and increase overall system value in every installation. Their compact size, packing either 2 or 4 channels into 1 RU, reduces rack costs and minimises space requirements. Integrated DSP reduces the need for external outboard equipment, drastically reducing installation effort and expense. Extremely high operational efficiency greatly reduces power consumption, resulting in the lowest thermal dissipation ratings in the industry, and minimises the need for external cooling devices. Additionally, each channel is capable of directly driving 70V/100V distributed loudspeakers, low impedance loudspeakers from 2 ohms, or any mixed configuration of low and high impedance output loads, making ALC’s extremely flexible and capable in a wide range of applications.
In-depth control and monitoring is accomplished via ArmoníaPlus system manager software. Assigning loudspeakers to ALC output channels is a simple, visual, drag and drop process. Loudspeaker groups and zones can also be created quickly by simply clicking on the images of the loudspeakers to be grouped together. Tailoring the sound and managing the system can be done at a remote, decentralised location. All ALC models can also be trusted in mission critical applications, such as fire alarm systems, thanks to the cleverly engineered power supply that allows reliable operation even when connected to a UPS. In addition, the per-channel, user-assignable fault-indicating GPIO connectors on the rear panel may be integrated with 3rd party monitoring and emergency notification systems.
