M14D

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 MediaMatrix, Crestron, AMX, Q-SYS control and monitoring systems).
Locally, the M14D HDSP+ETH lets the user access up to four presets per pushbutton on the rear panel.

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 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 continous 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

• Compact size – all models only 1 RU for reduced rack cost and space
• Light weight – all models only 7.4 kg (16 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 Armonía Pro Audio Suite™
• Interface available for MediaMatrix, Crestron, AMXcontrol, Q-SYS and monitoring systems
