Smart Rails Management (SRM) Technology: The QUATTROCANALI 4804 incorporates Powersoft’s patented Smart Rails Management technology, which optimizes amplifier efficiency by adjusting the power supply to match the load requirements. This innovation significantly reduces power consumption, regardless of the load conditions, leading to lower operational costs and enhanced performance. Additionally, SRM minimizes thermal dissipation, resulting in less heat generation and a reduced need for external cooling devices.

Versatile Output Capabilities: This amplifier is designed to handle a wide range of applications, operating with low-impedance loads starting from 2Ω. Furthermore, it supports 70V/100V distributed lines, allowing users to configure systems flexibly to suit various environments. This versatility ensures that the QUATTROCANALI 4804 can deliver optimal performance whether in live sound settings, fixed installations, or distributed audio systems.

Robust Power Supply: The QUATTROCANALI 4804 features a legendary Powersoft universal switch-mode power supply that can tolerate voltages up to 400VAC. This power supply includes Power Factor Correction (PFC), which enhances overall efficiency. Additionally, low inrush limiting reduces the initial surge of current during startup, minimizing the need for expensive power sequencers. This ensures reliable operation even when connected to an uninterruptible power supply (UPS), making it suitable for mission-critical applications.

Comprehensive Protection Mechanisms: The amplifier comes equipped with a fully protected circuit design to ensure reliable operation and longevity. Key protections include:

• AC Protection: Shuts down the power supply when the mains voltage is outside the operational range.
• Clip Limiter: Prevents distorted waveforms from reaching loudspeakers while maintaining peak power output.
• DC and VHF Protection: Safeguards outputs from infrasonic signals and harmful high-frequency signals.
• Short Circuit Protection: Automatically resets to protect against short circuits and other stressful events.
• Thermal Protection: Maintains safe operating temperatures, with the output stages tolerating temperatures up to 80°C (176°F).

Lightweight and Compact Design: Weighing only 7 kg (15.4 lbs) and occupying a single rack unit, the QUATTROCANALI 4804 offers a compact solution without compromising on performance. This lightweight design facilitates easy installation and transportation, making it ideal for both touring and fixed installations.

Remote Control and Monitoring: The amplifier supports comprehensive remote control and monitoring capabilities, allowing users to adjust settings easily. Control options include attenuation, high-pass filter selection, and gain adjustments via both software and hardware interfaces. This functionality enables real-time diagnostics and adjustments for optimal performance in diverse audio environments.
