Samson MXS3500 Overview

The MXS3500 by Samson is a two-rack-space, Class-H-designed professional power amplifier for live sound reinforcement. It is used in audio applications that require exceptional sound and high wattage such as DJ setups, houses of worship, health clubs, PA systems, live stage performances, rehearsals and more. It features 1900W of stereo power at 4 ohms and 5400W of bridged mono power at 4 ohms. The two channel amp employs an intelligent switch mode power supply that continuously monitors the signal level. This smart distribution helps eliminate excess heat or wasted energy. The MXS3500 also features low noise fans to ensure its power transformer has cool air.

The MXS3500 is built with a limiter and features detented level controls for each channel, as well as signal, 10 dB, and peak level LEDs for optimal use on dark stages. It is also built with XLR and 1/4″ inputs and has binding post and Speakon outputs. This amplifier has a 3-position filter (120 Hz, Full, and 28 Hz) selector switch for optimizing the power amps to your specific setup. A power cord is included.

  • 1100W power into 8 ohms provides plenty of power for live sound reinforcement
  • A limiter provides peak power delivery while minimizing distortion
  • Extensive 4-point protection circuitry (short circuit, DC output, over current, thermal)
  • 3-position mode selector switch allows for easy toggling between Mono, Stereo and Bridged Mono modes
  • Features LEDs for optimal use on dark stages and indicates your current operating mode and filter settings
