With 5,000W across four channels in a single rack space unit at a mere 8 kg weight, the MA68K is equally versatile in touring and permanently installed racks.Optimized for mid-sized sound systems and 4Ω loads, it is a fantastic value, practically as well as commercially.

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

·  Wide range AC power supply from 110V~240V 

Protections

· 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

General :

·  Compact size - all models only 1U for reduced rack cost and space

·  Light weight - all models only 8 kg for easier racking and shipping

·  Neutrik XLR balanced inputs with loop thru XLR and Speakon outputs connectors

·  Recessed stepped attenuators

·  Modular construction
