Beskrivning

Quattrocanali offers the renowned sound quality and reliability of all Powersoft’s Amplifier Platforms.

The patented SRM (Smart Rails Management) technology allows up for the maximization of the system’s efficiency.

With Output Powers ranging from 300W to 1200W per channel, in-depth control, and monitoring capabilities, Quattrocanali is designed to be conveniently tailored to all small to medium-sized installation projects.

Quattrocanali 1204 offers the traditionally amazing sound quality and reliability of all Powersoft products.

The patented SRM (Smart Rails Management) technology allows to maximize the efficiency of the system and drastically reduce power consumption in any load and usage condition. Quattrocanali features the lowest thermal dissipation in the industry, reducing the need for external cooling devices.

Quattrocanali is designed to operate with lo-Z (from 2 Ω) and 70V/100V distributed lines or any mix of the two.
DSP+D versions of the Quattrocanali grant in-depth control and monitoring via ArmoníaPlus, tailoring the sound and managing the system can be done by a remote, decentralized location.

This Amplifier Platform 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.
