Detailed Description X4L
X4L is a 4-channel high-performance amplifier platform in the Powersoft X Series range. It integrates a worldwide-compatible power supply, flexible input routing and extensive loudspeaker processing. Designed for the voltage demands of current high-performance loudspeakers, it delivers up to 300 Vpeak and a peak total output of 32800 W with all channels driven.
Physical inputs include 4 analog channels and 4 AES3 channels. The Dante version adds sixteen network-audio channels through two redundant RJ45 connections; this interface is version-dependent. An internal routing matrix combines the available sources, and a configurable input-backup policy can automatically change source if the primary signal fails.
The integrated DSP uses 40-bit floating-point processing, dual 24-bit Tandem converters and flexible FIR, IIR and hybrid crossover functions. Raised-cosine equalization, independent input and output delays, TruePower, RMS voltage / current and peak limiting provide comprehensive loudspeaker-management tools. Active DampingControl compensates for cable losses.
ArmoníaPlus provides a unified configuration and monitoring interface, with mobile Wi-Fi monitoring also described by Powersoft. The power supply supports single-, bi- and three-phase installations, with PFC, load balancing and Smart Rails Management. Electrical and thermal protection cover the amplifier and connected loads. The platform is intended for full-range loudspeakers, subwoofers, touring, arenas, concert halls, stadiums and multi-zone live venues.
