Product Highlights
• Output power optimized to match needs of Community loudspeakers.
• Drive low impedance 70V or 100V loudspeakers on any channel.
• Fast and easy access to complete Community loudspeaker library.

Product Overview
Community recommends our series of Amplified Loudspeaker Controllers (ALC) for all Community loudspeaker applications. ALCs 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 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-3202D 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.

Effortless Installation
• Compact size – 4 channels x 1 RU for reduced rack cost and space saving.
• Industry-leading integrated DSP reduces need for external outboard equipment drastically reducing installation costs.
• Lowest thermal dissipation ratings in the industry reducing the need for external cooling devices.
• Direct drive either low impedance loads or 70V / 100V Hi-Z distributed lines.
• Lightweight – for easier racking and shipping: 7.8 kg (17.2 lbs).
• Seamless integration into any networking environment – local and/or remote monitoring and operation via CAT5 or WiFi.

Features
Power Supply
• Universal switch mode power supply up to 400VAC tolerant with Power Factor Correction.
• Low Inrush Limiting reduces AC inrush current removing the need for expensive power sequencers.
• Detachable AC mains cable with IEC C19/22.2 (16A for EU 20 A for USA) socket.

Protections
Fully Protected Circuit Design With:
• AC protection: shut down power supply when AC mains voltage is outside operating range.
• Clip Limiter: prevents severely clipped waveforms from reaching loudspeakers while still maintaining full peak power output.
• DC Protection: protects against infrasonic signal at the outputs.
• VHF Protections: protects the loudspeakers against non-audible strong non-musical high-frequency signals.
• Short Circuit Protection: protects the amplifier from short circuit or other stressful events for the output circuits with automatic protection reset.
• Long-Term Limiter: protects the loudspeaker against steady long-term rms (non-audio) signals reducing maximum output.
• Thermal Protection: output stages operating temperature up to 80 °C (176 °F).
• Over-Current Protection: temporarily disables all outputs if power supply peak current threshold is exceeded automatically resumes normal operation after transient event subsides.
• Temperature controlled continuous variable speed fan front to back airflow.

General
• Fixed frequency switch mode output stage for high-grade sound accuracy.
• Patented Smart Rails Management technology maximizes system efficiency and drastically reduces power consumption in any load and usage condition.
• Standard Phoenix connectors: analog inputs audio outputs alarms and GPIO.
• Remotely input gain controls per channel.
• Remotely switchable double input (analog and Dante®) with assignable auto backup switching strategy per channel.
• Full matrix signal routing of inputs to loudspeakers.

Community Loudspeaker Preset Library
• Complete Community loudspeaker library allows users to select loudspeaker model type (Lo-Z 70V 100V) and application then automatically sets the appropriate FIR processing and multi-stage limiters.
• Each Community preset also includes loudspeaker-specific power/impedance values allowing ArmoniaPlus to automatically calculate and display the power needs and available headroom on each output channel plus the total power draw and headroom available from the ALC power supply. This feature removes all the guesswork normally required to match loudspeakers with appropriate amplifiers.
• Multiple loudspeaker wired in parallel may be assigned to each output. Total resultant impedance and power needs are calculated automatically.

Loudspeaker System Configuration
• Direct drive either low impedance loads or 70V / 100V Hi-Z distributed lines.
• Mixed configuration with Lo-Z/Hi-Z systems possible.
• Bridged mode low impedance (4Ω) per channel pair.

Interactive Tuning Plugin
• The Interactive Tuning plugin included in ArmoniaPlus supports importing/exporting transfer functions and spectrum traces for offline evaluation manipulation and equalization using SmaartV8 (separate purchase required).
• Perform standard live measurement and equalization within the ArmoniaPlus workspace.
• Draw custom target transfer curves using on screen EQ controls.
• Trace inversion trace capture and an extensive set of math operations are available to aid in system evaluation and tuning.
