The Powersoft Duecanali 3904 is a professional power amplifier designed to meet the most stringent requirements of professional users in professional fixed installations. Designed by Powersoft R&D team the Duecanali 3904 is exclusively built in Italy with internal components selected for premium quality and proven durability. Each modular subassembly is pre-tested, and the assembled Duecanali 3904 receives a rigorous 48 hours burn-in before through final check-out on precision test equipment for total quality control.The Duecanali 3904 incorporates the legendary patented Powersoft universal switching mode power supply up to 400VAC tolerant with Power Factor Correction providing users with worldwide AC acceptance and low consumption.
Powersoft bridgeable switch mode fixed frequency class D patented outputs provide high quality sound, excellent damping factor and cooler circuits for stable performances over time and longer amplifier life. LCD display with lockable user menu for easy control of all amplifier settings. Auxiliary inputs, triggered by 24V command input for alarm and pre-recorded emergency messages. Output relay for each amplifier channel for reporting single channel fault conditions. The Duecanali 3904 is able to drive 70V/100V lines without external transformers. Output voltage limiter should be applied, and depending on the speakers being used a high pass filter (HPF) may be required.
