Powersoft Duecanali 3904 DSP+AESOP Data Sheet
Duecanali 3904 DSP+AESOP
2-Channel Power Amplier with DSP and Networking for High-Performance Installed Sound Systems
®
▶ Medium to large-scale venues
▶ Main systems, central or
distributed, subwoofers, hi-Z/lo-Z
▶ Emergency systems (IEC 60849)
▶ Stadiums, arenas
▶ Theaters, concert halls
▶ Houses of worship
▶ Convention centers
▶ Amusement parks, themed
entertainment
▶ Cruise ships
Designed for long-term safe and
reliable operation, the Duecanali
3904 DSP+AESOP suits both low
impedance and constant voltage systems
equally well.
A fully integrated state-of-the-art DSP
yields extensive system management
functionality. In addition to sound
shaping and limiter functions in unique
Powersoft style, the DSP hardware and
Armonía Pro Audio Suite™ software
enable compliance with IEC 60849
for the crucial requirements of sound
systems for emergency purposes.
The AESOP interface provides two
standard Ethernet ports and hub
functionality for two AES3 digital audio
streams equivalent to 4 analog signal
channels over the same RJ45, allowing
for a redundant ring architecture too.
Powersoft’s legendary efciency
saves valuable energy, keeping both
operational cost and ‘carbon footprint’
at a minimum: the Duecanali
3904 DSP+AESOP shines with
outstandingly low power consumption
and heat dissipation; this has direct
positive effects on investment and
recurring costs from the AC mains
supply and air conditioning/cooling
systems – not to mention the benets to
the environment for a more eco-friendly
planet.
