About Powersoft M28Q

700 W at 4Ohm from each of four channels with bridgeable pairs: a single M28Q is good for powering a complete little bi-amped stereo system, a 3-way mono stack of decent size, a variety of floor monitors.

All at a quality level as can be expected from Powersoft. Optimized for 4Ohm loads, the M28Q is a fantastic value, practically as well as commercially.

In use worldwide by leading touring and event sound companies, Powersoft amplifiers are preferred among the top ranking system designers, sound engineers, and contractors for providing reliable premier-grade power and headroom in the smallest possible package size.

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.

Equally versatile in both portable and installed system configurations and with its 4 channels delivering up to 2,800 W all neatly packed in one single rack unit weighing just over 7 kg / 16 lb, the M28Q is a flexible, cost-effective solution for small to medium sound systems.

Benefitting from core technologies of Powersoft's flagship K Series, the M Series sets a class standard in efficiency, leading to low power consumption, and consequently to substantial money savings on electricity, all in an eco-friendly way.

Minimum heat dissipation makes the M28Q suitable for hot or otherwise challenging environments.

Added the legendary sound quality thanks to Powersoft's unique, patented Class D output stage design, the M28Qrepresents a fantastic value, practically as well as commercially.

The M28Q comes with 4 years warranty and, like all Powersoft products, is entirely designed and made in Italy.

Features

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

Protections
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 Degree C (167 Degree F)
• Temperature controlled continous variable speed fan, front to back airflow

General
• Compact size - all models only 1 RU for reduced rack cost and space
• Light weight - all models only 7.4 kg (16 pounds) for easier racking and shipping
