- Four-channel power amp that can operate in both high-impedance (70V/100V line) or low-impedance (4O/8O) modes simultaneously
- 70V or 100V mode can be assigned to every pair of channels without affecting the number of available output 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 circuit improves the already highly efficient Class D circuit topology, bringing the efficiency level of the amplifier's output stage up to over 90%
- Features 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
The XMV4280 from Yamaha is a 4-channel power amplifier that boasts Class-D efficiency ideal for commercial installation sound systems.
Its innovative YDIF digital audio format makes this power amp effortless to set up.
