4-Channel High-Performance Power Amplifier with DSP and Ethernet

The X4L has been designed to deliver the output voltage required by the latest generation of high performance loudspeakers.

Powersoft's legendary power supply is suitable to Single Phase, Bi-Phase or Three Phase operation from 85 VAC up to 460 VAC without need of selection. True Three Phase load balancing is directly achievable without any complex load assignment in the power distribution system. Powersoft X4L provides four fully processable channels and selectable inputs from analog sources as well as digital AES3 and two redundant Dante* streams.

Channel mixing and routing can be easily performed thanks to the integrated low latency DSP, providing the highest degree of freedom in sound shaping and speaker management. Full support of 100 Mbps and Gigabit Ethernet makes it easy to integrate Powersoft X4L into any existing infrastructure. Completely integrated into ArmoníaPlus, the Powersoft X4L interface is also available for smartphone and tablet, providing a new experience in power management.

* DANTE version only

Powersoft X Series raises power amplification to a new standard of quality and usability. Powersoft X Series innovates the concept of amplifier platform: it implements a new system of channel routing, new worldwide compatible three phase power supply and a revolutionary full featured DSP.

Powersoft X Series natively supports AES3, two redundant Dante by Audinate digital streams and analog inputs, providing up to 4 different selectable input sources per channel.
