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.
