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.
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 networkProtections
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 airflowGeneral
