Yamaha XMV4140 4 Channel Power Amplifier

Working Smarter and Harder

The XMV4140 is also equipped with automatic protection functions, creating an operational environment that’s unphased by unfavorable conditions. The XMV4140’s intelligent engineering actively protects the unit from overheating, overcurrent, low-load impedance, and other ordinarily damaging situations for an in-field dependability like no other power amp. Detecting and preventing roadblocks in your system carries over to the XMV4140’s dual redundant functions: Backup mode and Override mode. In Backup mode, this power amp will automatically switch to analog inputs when incoming digital input interruptions are detected, with the brains to return to the digital input once the original source is recovered. The other side of the coin is Override mode, which switches input sources within a channel — free of interruptions — when a voice input from any analog input is detected. Either way, the XMV4140 will always have your back.

Equipped with the newly developed YDIF digital audio format for easy setup.

• 4x 140W at 8Ω/4Ω
• 4x 125W at 100V/70V lines
• 2x 280W at Double Power Mode (8Ω/4Ω)
•  

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 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 patent pending circuit improves the already highly efficient Class D circuit topology, bringing the efficiency level
Feature a Power Factor Correction equipped switching power supply, ensuring harmonic control and decreasing the amount of
Powerful, intelligent protection features for more reliable operation.
