480W RMS @2Ω 4-channel wide range class-D amplifier with complete variable x-overs


The MTX TX480D 4-channel Amplifier (4x120W RMS @2Ω) is a nugget. He wakes up any speaker, and makes it go straight. It's so small it's hard to believe it's so powerful: 480W RMS total! It operates in Class-D to provide maximum power using minimum current. Its CMS construction is at the top of current technology. Its active x-overs are very flexible, they allow a 4-channel configuration (front + rear speakers) as well as a 3-channel configuration (front speaker + subwoofer/box). It was classified "best class-D amplifier" by the Car&Hifi magazine (9/2017)

  • 90db : maximum 8 hours/day
  • 92dB : maximum 6 hours/day
  • 95db : maximum 4 hours/day
  • 97db : maximum 3 hours/day
  • 100db : maximum 2 hours/day
  • 102db : maximum 90 minutes/day
  • 105db : maximum 60 minutes/day
  • 110db : maximum 30 minutes/day
  • 115db : maximum less than 15 minutes/day
  • 120db : immediate danger, 0 minute/day
