M30D

2-Channel Power Amplifier for Touring and Installation

Overview

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 a 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. MyPowersoft services are available for this product.

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 an 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
Compact size - all models only 1 RU for reduced rack cost and space
Lightweight - all models only 7.4 kg (16.3 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
