The Powersoft M28Q is a 4-Channel power amplifier with 700 watts at 4 ohms 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, or even a comprehensive PA system with multiple 70V lines. All at a quality level as can be expected from Powersoft. Optimized for 4 ohm 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.

Powersoft M28Q Features:

  • Weight and space saving: highly efficient switch mode PSU and Class D design in only one rack space (1U) and appr. 7kg/15lbs
  • Outstanding sonic quality per design, including patented output filters
  • Power saving: reduced current draw resulting in lower power consumption and cost – Green Audio Power™!
  • Compact size and light weight - all models only 1 RU and 12 kg (26 pounds) for easier racking and shipping
  • Powersoft legendary universal switch mode power supply up to 290V tolerant , compact, high performance
  • AC mains voltage switchable 115V/230V
  • Detachable AC mains cord
  • Low Inrush Limiting reduces AC inrush current, removing the need for expensive power sequencers
  • Fixed frequency switch mode output stage for highest grade audio accuracy
  • Patented output filter with ripple cancellation network
  • Recessed front panel level controls and LED indicators
  • Temperature controlled continuous variable speed fan, front to rear airflow
  • Neutrik® XLR balanced input and Speakon® output connectors
  • Fully protected circuitry design including DC, infrasonic, high frequency, thermal overload and short circuit
  • Clip and RMS limiters to protect loudspeakers from damage from clipped wave forms and steady non-audio signals
