Sold Powersoft M28Q HDSP+ETH 4 Channel Power Amp - Kent

Description

M28Q Overview

Maximum efficiency with minimum current draw, heat dissipation, and power consumption, resulting in "green" products, saving the user a substantial amount of money over time.

The M28Q 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 ArmoníaPlus (Interface available for MediaMatrix, Crestron, AMX, Q-SYS control, and monitoring systems).

Locally, the M28Q HDSP+ETH lets the user access up to four presets per pushbutton on the rear panel.

M28Q 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
