Like all M Series models, the M30D is optimized for 4Ω, and with its output power ideal for small to medium sized sound systems where e.g. no more than two 8Ω loads are connected in parallel to an amplifier channel: Why overpaying for amplifiers capable of driving 2Ω loads?
Alternatively, the M30D can drive constant voltage lines directly where multiple loudspeakers are required, but only few different signals.
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 M30D 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 and monitoring systems).
Locally, the M30D HDSP+ETH lets the user access up to four presets per pushbutton on the rear panel.
- Advanced switch-mode power supply technology for high performance and compact size
- Fixed frequency switch mode output
- Patented output filter with ripple cancellation network
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
