Powersoft M14D

Description


Where not high output power or channel count but a dependable amplifier is required, the M14D is the right tool. Built on the same technologies as Powersoft′s prominent touring amplifiers, the M14D comes to play in smaller quality sound systems.

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.

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 M14D 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 M14D HDSP+ETH lets the user access up to four presets per pushbutton on the rear panel.
