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.
