Yamaha – XMV4280 4 Channel Amplifier

Yamaha

Multi-channel power amplifiers designed specifically to benefit installation sound systems.

SKU: XMV4280 Categories: , ,

Description

Multi-channel power amplifiers with features designed specifically to benefit installation sound systems.

Features

  • Four-channel power amp that can operate in both high-impedance (70V/100V line) or low-impedance (4Ω/8Ω) modes simultaneously.
  • 70V or 100V mode can be assigned to every pair of channels without affecting the number of available output channels.
  • The newly developed Double Power Mode function effectively doubles the output power of selected channels.
  • Equipped with YDIF* digital audio format 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, new, 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.

* YDIF: the newly developed digital transmission format; a unique propriety Yamaha technology that delivers 16ch audio and word clock
transmission via standard CAT5 Ether cable.
