Power Supply and Efficiency: The Quattrocanali 2404 amplifier features Powersoft’s Smart Rails Management (SRM) technology, which maximizes system efficiency by adjusting power based on load and usage. This design significantly reduces power consumption and minimizes heat generation, allowing for dependable performance in diverse environments. Equipped with a universal switch-mode power supply with Power Factor Correction (PFC), the amplifier ensures stable operation across voltage ranges from 100-240 V. The detachable AC mains cable is compatible with EU and USA standards, making it versatile for different setups.

Comprehensive Protection Features: To safeguard connected equipment, the Quattrocanali 2404 is built with multiple protective measures. It includes AC protection that shuts down the power supply when voltage levels are unsafe, and a clip limiter that prevents speaker damage by limiting distorted waveforms while maintaining peak output. Other features include DC protection to filter out infrasonic signals, VHF protection to guard against high-frequency disturbances, and short circuit protection that automatically resets after stressful events. Thermal protection further extends system life, with an adaptive fan that adjusts speed based on temperature.

Flexible Connectivity and Control: Designed for versatile applications, the Quattrocanali 2404 offers flexible control options. RS-485 remote control and monitoring capabilities allow users to manage diagnostics, gain settings, and channel operations remotely. Dual input channels enable switching between main and auxiliary inputs for each channel, making it easy to integrate into complex setups. Phoenix connectors support analog audio, auxiliary power, alarms, and GPIO integration, allowing seamless connectivity with external systems.

Customizable User Settings: The amplifier provides several user-selectable settings, including gain and sensitivity adjustments per channel, maximum output power limitations, and control over mains current draw. Users can lock their configurations with an access code to secure their settings. These customization options make the Quattrocanali 2404 adaptable for various professional audio applications, from concerts to critical safety systems.

Compact and Lightweight Design: The Quattrocanali 2404’s 1 RU size and 7 kg weight make it easy to handle, transport, and install, especially in rack-mounted setups. Its compact, space-saving design reduces overall rack costs and simplifies system integration. This lightweight construction, paired with its power and flexibility, makes it an ideal choice for demanding, space-limited professional environments.
