Yamaha XMV4280 70 Volt Commercial Multi-Channel Power Amplifier 4 x 280 watts

Yamaha XMV4280  70 Volt Commercial Multi-Channel Power Amplifier 4 x 280 watts

The Yamaha XMV4280 power amplifier enables both 70V and 100V operation for every pair of channels by easily selecting the preferred mode using the dip switches on the rear panel. High impedance operation often requires the use of two combined channels in bridge mode, but with Yamaha XMV4280 amplifier, 70V or 100V mode can be assigned to every pair of channels without affecting the number of available output channels.

New Doubled Power Mode

The Yamaha XMV4280 power amplifier has new developed Double Power Mode function effectively doubles the output power of selected channels in order to drive speakers with higher output power. This means that speakers with varying output capacities can be powered simultaneously by the same amplifier, adding flexibility to system design and configuration.

Selectable input formats for a wider range of applications

The Yamaha XMV4280 amplifier comes equipped with  the newly developed YDIF digital audio format. The YDIF allows easy setup with the use of Ethernet cables while Dante models can be used for larger venues where long distant cabling is required.

Best Installation Amplifier Ever

The Innovation of Yamaha XMV4280 with its new patent pending circuit that improves the already highly efficient Class D circuit topology, bringing the efficiency level of the amplifier's output stage up to over 90%. This is achieved by automatically switching the circuit to match the corresponding output voltage. In high-impedance connections, both 70V and 100V operation can be achieved since the circuit is already capable of operating in high voltages. However, using the same circuit in low-impedance operation can mean excessive energy loss, so by automatically switching to a lower voltage drive, efficiency is improved significantly without sacrificing crucial aspects of the amp's performance such as keeping the distortion levels to a minimum.
