The M50Q HDSP+ETH version provides onboard 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 M50Q HDSP+ETH lets the user access up to four presets per pushbutton on the rear panel.

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
- Analog Devices ADAU 1701 DSP architecture
