Powersoft M20D

Description


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.

Maximum efficiency warrants minimum current draw, heat dissipation and power consumption, resulting in "green" products, saving the user a substantial amount of money over time.

The M20D HDSP+ETH version provides on-board DSP and Ethernet interfaces.
The high-performance DSP is hidden inside and safe against accidental or intentional tampering; monitoring and amplifier settings can be done via Armonía Pro Audio Suite™(Interface available for MediaMatrixCrestronAMXcontrolQ-SYS and monitoring systems).
Locally, the M20D HDSP+ETH lets the user access up to four presets per pushbutton on the rear panel.
