Smart Rails Management (SRM) Technology: The Powersoft QUATTROCANALI 1204 leverages patented Smart Rails Management (SRM) technology to maximize efficiency and minimize power consumption. SRM optimizes energy use based on the amplifier’s load, significantly reducing environmental impact and operational costs.

Universal Power Supply with Power Factor Correction: Equipped with a universal switch-mode power supply that includes Power Factor Correction (PFC), the amplifier can handle voltages up to 400VAC, providing reliable operation in a wide range of environments. The low inrush limiting feature eliminates the need for costly power sequencers, enabling dependable performance even when connected to uninterruptible power supplies (UPS) for critical systems like fire alarms.

Exceptional Thermal Management: With ultra-low thermal dissipation, the QUATTROCANALI 1204 ranks as one of the industry’s most efficient amplifiers in thermal management. This feature reduces the need for additional cooling equipment, enhancing usability in compact installations and extending the amplifier’s operational life.

Flexible Output Options: The amplifier supports both low-impedance (Lo-Z) loads starting from 2Ω and 70V/100V distributed lines, allowing for varied configurations in different environments. This flexibility makes it suitable for complex audio setups requiring mixed output options.

Comprehensive Protection Features: The QUATTROCANALI 1204 includes an extensive array of protection mechanisms to safeguard both the amplifier and connected speakers. Protections include AC, clip limiter, DC, VHF, and thermal protection, as well as short-circuit and long-term limiter safeguards. These protections ensure durability and longevity in high-demand applications.

Remote Control and Monitoring: The amplifier provides extensive control options through software and hardware interfaces, allowing users to manage settings such as gain, attenuation, and high-pass filters. Remote ON/OFF functionality and diagnostic monitoring ensure smooth operation and flexibility in professional audio environments.

Compact and Lightweight Design: Weighing only 7 kg (15.4 lbs) and occupying 1 RU of rack space, the QUATTROCANALI 1204 is designed for convenient integration and transport, making it ideal for mobile setups and space-conscious installations.
