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

Power supply

  • Advanced switch-mode power supply technology for high performance and compact size
  • Fixed frequency switch mode output
  • Patented output filter with ripple cancellation network

Protections

Fully protected circuit design with:

  • 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

Digital Signal Processing*

  • 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

General

  • Direct drive constant voltage, 70V Hi-Z distributed lines*
  • Compact size – all models only 1 RU for reduced rack cost and space
  • Lightweight – all models only 7.4 kg (16.3 pounds) for easier racking and shipping
  • Neutrik XLR balanced inputs with loop thru XLR and Speakon outputs connectors
  • Recessed stepped attenuators
  • Modular construction
  • Full four years warranty

Remote management*

  • Control and monitoring through ArmoníaPlus
  • Interface available for MediaMatrix, Crestron, AMX, Q-SYS control, and monitoring systems

* = HDSP+ETH version with HPF and output voltage limiter preset/external HPF and output voltage limiter required with no-HDSP+ETH version.
