More about Yamaha's XMV Power Amplifiers

Specifically designed to complement sound systems in commercial installations, the XMV Series from Yamaha is a family of 8 multi-channel amplifier models that boast a variety of output power capabilities, flexible inputs and outputs, and support for both high- and low-impedance connectivity.

An innovative circuit characteristic of XMV amplifiers improves the already highly efficient Class D circuit topology, bringing the efficiency level of the amp's output stage up to over 90%. This is achieved by automatically switching the circuit to match the corresponding output voltage.

XMV power amps can operate in both high-impedance (70V/100V line) or low-impedance (4Ω/8Ω) modes simultaneously, eliminating the need for additional equipment, as well as streamlining the installation process.

XMV also enables both 70V and 100V operation for every pair of channels by simply 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 XMV, 70V or 100V mode can be assigned to every pair of channels without affecting the number of available output channels. 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.
