Yamaha XMV4280 Power Amplifier Four Channel

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.
