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 the 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 400V
AC
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 a 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.
Optional DSP provides to
Duecanali 3904 DSP+AESOP
full high-quality onboard sound processing. Sensing and communication board, standard on RS485 bus, Ethernet optional, provides full control and monitoring through Armonía Plus, compatible with all other Powersoft K, M, D, Q, and Ottocanali Series amplifiers.
Interface available for MediaMatrix, Crestron, AMX control, Q-SYS, and monitoring systems.
The Duecanali 3904 is able to drive 70V/100V lines without external transformers. Output voltage limiters should be applied, and depending on the speakers being used a high pass filter (HPF) may be required.

✓ Full four years warranty
✓ Options & accessories:
▶ SmartCard, for firmware updates or preset storage
Power Supply
Powersoft legendary universal switch mode power supply up to 400VAC tolerant with Power Factor Correction
Patented output filter with ripple cancellation network
Low Inrush Limiting reduces AC inrush current, removing the need for expensive power sequencers
Detachable AC mains cable with IEC C19/22.2 (16A for EU, 20 A for USA) socket
Protections
Ac protection: shut down power supply when AC mains voltage is outside operating range
Clip limiter: prevents severely clipped waveforms from reaching loudspeakers, while still maintaining full peak power output
DC protection: protects against infrasonic signal at the outputs
VHF protections: protects the loudspeakers against non audible, strong, non musical high frequency signals
Short circuit protection: protects the amplifier from short circuit or other stressful events for the output circuits with automatic protection reset
Long term limiter: protects the loudspeaker against steady long term rms (non audio) signals reducing maximum output
Thermal protection: output stages operating temperature up to 80 °C (176 °F)
Temperature controlled continous variable speed fan, front to back airflow
Temperature forecast with LCD traced historical behaviour
