PowerSoft M 20 D HDSP+ETH

Like all M Series models, the M20D is an outstanding value in any smaller to medium sized sound system where an efficient, compact and good sounding amplifier is expected to work reliably over a long period. Since 2Ω-capability is usually not needed in smaller systems, the M20D is properly dimensioned with its 4Ω optimization. In use worldwide by leading touring and event sound companies, Powersoft amplifiers are preferred among the top ranking system designers, sound engineers, and contractors for providing reliable premier-grade power and headroom in the smallest possible package size.
Alternatively, the M20D can drive constant voltage 70V lines directly where multiple loudspeakers are required.

Features:

• Advanced switch-mode power supply technology for high performance and compact size
• Fixed frequency switch mode output
• Patented output filter with ripple cancellation network
• 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 75 °C (167 °F)
• Temperature controlled continous variable speed fan, front to back airflow
• Analog Devices ADAU 1701 DSP architecture
• 24 bit @ 48 kHz, 120 dB S/N AD/DA converters
• Separate input/output EQ's with numerous filters of various types up to 48 dB/oct
• Peak, RMS, and frequency dependent limiters
• Delay for time alignment
• Direct drive constant voltage, 70V Hi-Z distributed lines**
• Compact size - all models only 1 RU for reduced rack cost and space
• Light weight - all models only 7.4 kg (16 pounds) for easier racking and shipping
• Neutrik XLR balanced inputs with loop thru XLR and Speakon outputs connectors
• Recessed stepped attenuators
• Modular construction
