Powersoft Duecanali5204 and Duecanali3904 Professional Amplifiers

Powersoft Advanced Technologies, LLC, a world leading manufacturer of superior quality digital power amplifiers for the professional audio market, is proud to present the first two models of its new Installation Series at this year’s InfoComm 2009 (Booth 6384), the Duecanali5204 and Duecanali3904. These amplifiers are installation versions of the K-3 and newly introduced K-2, delivering an efficient and reliable energy saving design in a compact one-rack unit space, while still maintaining high-output wattage and crystal clear audio. The design offers 40% to 60% savings on operating costs over traditional amplifiers of the same power rating.

The Duecanali5204 offers a thundering 1400W of power with a speaker load of 8-ohms, 2600W at 4-ohms and 2800W at 2-ohms in stereo configuration. In bridge mode the output wattage is a massive 5200W at 8-ohms and 5600W at 4-ohms. The Duecanali3904 has a generous power range of 1000W with an 8-ohm speaker load, 1950W at 4-ohms and 2400W at 2-0hms in stereo configuration. In bridge mode the unit delivers a steady 3900W at 8-ohms and 4800W at 4-ohms. The available power yield from both units insures undistorted peak sound performance.

The Installation Series incorporates the innovative and patented Powersoft universal switching mode power supply, providing users with worldwide AC operation in voltage ranges from 95 to 265V. The Power Factor Correction (PFC) technology employed in the design tolerates up to a 400 VAC spike without interrupting rated audio output and clarity. The design also features low-power consumption with an incredible Power Factor efficiency of more than 0.90 from 500W to full power. This yields a 40% to 60% reduction in current draw over to traditional power amplifiers without PFC, helping to lower the carbon footprint and delivering a sensible economic benefit for installations. These amplifiers pay for themselves over time through equivalent power savings.
Powersoft’s bridgeable switch mode fixed frequency class D patented outputs generate high-quality sound with an excellent damping factor and the amplifier circuits run cooler for stable performance over time, resulting in longer amplifier life and reduced external cooling costs. Both units feature an LCD display with lockable user menu for easy control of all settings.

Offering DSP for full high-quality, on-board sound processing with up to 16 EQ filters per channel, the Installation Series is equipped with FIR filters with a cross-over slope of up to 48 dB per octave. The DSP package is capable of up to two seconds of delay per channel for time correction between satellite speakers. The peak limiter and true power limiter functions offer complete loudspeaker protection, while the patented damping factor and cable resistance compensation network offers a tight low end that is independent from cable section and length.

The Installation Series comes with a sensing and communication board that uses a standard RS-485 bus and offers an optional Ethernet connection through Powersoft’s KAESOP board that is able to drive two AES3 channels over the same CAT5 cable. This provides full control and monitoring through proprietary software running on an external PC. The software is compatible with all other Powersoft K, D, Q and QTU Series amplifiers.

With an astonishing signal to noise ratio greater than 110 dB for the Duecanali3904 and 112 dB for the Duecanali5204, each unit offers a Total Harmonic Distortion (THD), SMPTE and DIM30 Inter-modulation that is less than 0.5% from 1W to full power. The Installation Series demonstrates top-class performance that is similar to the acclaimed K Series, which has been available since 2005 via the best rental companies worldwide.

Rear panel input/output connectors are based on Euro blocks (Phoenix type) with auxiliary inputs that are triggered by an external 24V DC input for evacuation/emergency pre-recorded messages and doubled outputs per channel for easy of connection.

Two relays on the output circuits provide alarms for main power drop, short circuit, open circuit and thermal protection based on single channel information for system confidence monitoring. The Installation Series Duecanali5204 and Duecanali3904 amplifiers load monitoring information follows the EN60849 standard.

Designed by the Powersoft R&D team, the new Installation Series models are exclusively manufactured in Italy with internal components selected for premium quality and proven durability. Each modular subassembly is pre-tested, and the assembled Installation Series receives a rigorous 48 hours burn-in before final check-out on precision test equipment for total quality control.
