The ALC Director features a powerful 8-channel DSP-based controller with 8 bridgeable, new generation ClassD amplifier stages. With the 8 individually addressable inputs, a free-configurable input / output matrix is formed. Each channel accepts analogue or up to 192kHz.digital AES3 signals, that are up/down-sampled to 96kHz native processing.

 The future-upgradable powerful DSP engine enables minimal latency during processing of even the most complex (IIR, FIR) algorithms. Features include 8-band (shelf/pass/parametric) equalising per channel, delay, phase, factory presets for all systems and system configurations, user-presets, event-logging and system feedback.

For fully-intuitive control and feedback, the Director features on-unit control over the complete amplifier and processor sections through a 3.12” (256 x 64 pixels) monochrome OLED display, a multi-colour LED-illuminated rotary encoder and eight multi-colour LED-illuminated channel buttons.

The Class-D amplifier control loop delivers exceptionally low intermodulation figures and significant improvement over cone excursion and transient response. This unique technology is the perfect drive-engine for the high-resolution Alcons pro-ribbon systems.

The four digitally controlled, highly efficient main power supplies with active Power Factor Correction, enable maximum output while allowing worldwide input voltage ranges.

The modular design of the complete ALC, caters for “in-the-field” servicing and upgrading; The 2 power/amplifier packs can be exchanged in case of emergency, significantly reducing down-time. The DSP is mounted on a separate PCB, thus can be easily “future-proof” upgraded when required.

 The Director is integrated in ALControl™, Alcons Audio’s proprietary, Ethernet-based network for controlling individual or clusters of amplified loudspeaker controllers.

Through two additional RJ45 connectors (redundant) and optional network modules, the Director is prepared for different audio-over-network standards.

The ALC Sentinel features a powerful 4-channel DPS-based controller with Class-D amplifier stages. The 4 individually addressable inputs accept analogue or up to 192 kHz digital AES3 signals, that are up/down sampled to 96 kHz. by the custom high-end sample rate converters.

The future-upgradable powerful DSP engine enables minimal latency during processing of even the most complex (IIR, FIR) algorithms. Features include 6-band (shelf/pass/parametric) equalising per channel, delay, factory presets for all systems and system configurations, user-presets, event-logging and system feedback.

A Linux-based micro-computer “oversees” and controls all processes. The full-colour TFT touch screen and the multi-colour LED illuminated encoder in combination with tab-based menu structure offers intuitive control over the amplifier and processor sections, while reducing the number of “wearable” components.

The Signal Integrity Sensing™ circuit dynamically compensates the effects of long speaker cables; This results in a tight sub and bass response regardless of cable length or impedance (system damping factor of 10.000) and without the need for manually entering cable parameters. SIS™ also caters for futher reduced distortion (optimized cross-over drive).

The 4 patent-pending ClassD amplifier stages are 93% efficient and offer one of the lowest THD in the industry. Together with the 2 (redundant) switch-mode power supplies, the Sentinel3 delivers a total of 3.000 W. The modular design makes for easy “in-the-field” servicing and future upgrades.

The Power Detection Circuit automatically select the correct operating AC current 115 V / 230 V and protects against overload above 400 V.

Individual Sentinels can be simply controlled through a VNC app. on any mobile device; More complex Sentinel clusters can be controlled via the ALControl™ Ethernet-based remote-control connection. Internal slots are available for optional Audio-over-network plug-in modules.
