The Yamaha XMV4280-D 4 channel power amplifier has features are designed sepcifically to benefit installation sound systems.

Yamaha XMV4280-D Features:

  • Four-channel power amp that can operate in both high-impedance (70V/100V line) or low-impedance (4 Ohm/8 Ohm) modes simultaneously.
  • 70V or 100V mode can be assigned to every pair of channels without affecting the number of available output channels.
  • Double Power Mode function effectively doubles the output power of selected channels.
  • Equipped with Audinate's digital audio network Dante for simple and fast system configuration. 
  • Easy setting such as the mute on/off or attenuator changes with MTX Editor when used in system with MTX Series.
  • An innovative patent pending circuit improves the already highly efficient Class D circuit topology, bringing the efficiency level
    of the amplifier's output stage up to over 90%.
  • Feature a Power Factor Correction equipped switching power supply, ensuring harmonic control and decreasing the amount of
    current draw while maintaining the same output power.
  • Powerful, intelligent protection features for more reliable operation.
