Features:

New generation DA series industrial design by DWiD ( Founder: David Wathen ) High power output in 1U high space chassis, optimization of ventilation system design, better heat dissipation, longer working hour.

Design aim to audio application, the SMPS power circuits adopts APFC and soft switch technology, not only support universal 90~285 voltage working, but also auto adapts local power grid voltage fluctuation and harmonics interference, provide sustained stable and clean power.

1U rack mount space

Self-adaptive variable turbulence modulation technology overcoming the traditional Class D amplifier output easy to resonance problem, big improved in big sound pressure output sound quality, reduced distortion effectively, raised more dynamic headroom, in order to produce more detail of sound, make sounds more clean and powerful.

Variable turbulence modulation technology

Amplifier output board coil filter front and back, current signal .. multiple point detection and sampling feedback control technology, thus the amplifier has big ability adapt to many loading types and different application, including Resistance/ Capacitive/ Inductive loading and mixed.

Multiple detect point feedback control circuit technology

Variable turbulence modulation technology and Multiple detect point feedback control circuit technology, Enable New DA series has stable working ability even on lower impedance loading, full series DA amplifier support 2 ohms loading, to adapts more projects application.

Stabilize low impedance loading

Innovative overload output power control circuits, in any loading situation can providing non-stop sound /power output. In short circuit or very low impedance loading situation the amplifier will trig the compressor activate in very short time, does not affect the sense of hearing ; While amplifier detect circuits keep receive same fault signal, the amplifier will activate protection automatically.

Innovative output power controlAPFC(Active Power Factor Correction)

Fully compatible worldwide safety and EMC certification.

Excellence EMC performanceProvide over load, over heat, output short circuit, output DC, under voltage protection.

Thoughtful and complete protection

Applications:Rental audio system, Theater, Stadium, Night club, Hotel banquet hall and open space, Conference hall, Department store, Shopping mall show area, Art Center, Exhibition…
