Quattrocanali 1204 DSP 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 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, decentralised 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. MyPowersoft services are available for this product.
