description
Quattrocanali 1204 offers the traditionally amazing sound quality and reliability of all Powersoft products.
The patented SRM technology (Smart Rails Management) allows to maximize the efficiency of the system and drastically reduce the power consumption under all load and usage conditions. Quattrocanali has the lowest heat dissipation in the industry, reducing the need for external cooling devices.
Quattrocanali is designed to operate with distributed Lo-Z (from 2 Ω) and 70V/100V lines or a mixture of both. The DSP+D versions of the Quattrocanali allow detailed control and monitoring via ArmoníaPlus, allowing sound customization and system management from a remote, decentralized location.
Thanks to the sophisticated power supply, which enables reliable operation even when connected to a UPS, this amplifier platform can also be used in critical applications such as e.g. As fire alarm systems are used.
