Biamp Community ALC-404D 4 Channels x 400W + DSP and Dante Amplified Loudspeaker Controllers - 911.1353.900

Community Pro ALC-404D provides 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 Professional Loudspeakers application. Standard Ethernet communication protocols allow for fast system design, system control, and remote system monitoring. Analog and Dante® inputs are included in each model, for 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.

In-depth control and monitoring is accomplished via ArmonìaPlus System Manager Software. Tailoring the sound and managing the system can be done at a remote, decentralized location. The ALC-404D 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 to the per-channel, user-assignable fault-indicating GPIO connectors on the rear panel.

Packing 2 channels into 1 RU, reduces rack costs and minimizes space requirements for the ALC-3202D. The industry-leading 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 minimizes the need for external cooling devices.

The Amplified Loudspeaker Controller (ALC) provides four channels of power amplification and digital signal processing with analog and Dante inputs. Total available power can be safely distributed asymmetrically across the outputs in any combination of low impedance and 70/100V loads in single ended and/or bridged configurations. Power delivered from each output is individually monitored and automatically limited to the stated, safe operating ranges.

Biamp-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.

ALCs 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 minimizes space requirements. The industry-leading 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 minimizes 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 ALCs extremely flexible and capable in a wide range of applications.
