Overview

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.

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 the 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 continuous variable speed fan, front to back airflow
