MB series

MB series positioned in the middle-range market, good sound and reliable quality make of MB series the best option for entertainment applications due to its long lasting.
MB series adopt new upgraded circuitry and use more efficient toroidal transformer power supply by controlling the magnetic field interference and reducing the weight of the product. With the new upgraded circuitry design, the hum noise is reduced making background music wider and deeper, much more detailed and penetrating for off beat sound.
MB series can be used for various kinds of entertainment and multimedia projects.

Features

  • Class AB (MB2000/MB2500) and Class H (MB3500/MB4500/MB5500) power modules.
  • XLR signal input and SpeakON Nl4.
  • Specific optical volume control technology in order to increase the S/N rate.
  • Adopting temperature gain control technology, it stabilizes the power output with 8Ω/4Ω load.
  • Protection functions added: Short circuit, DC, clip limiter, over-heat,  over-load.
  • Stable and reliable quality due to its new upgraded circuitry and high quality toroidal transformer power supply.
