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.

A new switching power supply equipped with Power Factor Correction is also included to ensure harmonic control and decrease the amount of current draw while maintaining output power. The Double Power Mode function effectively doubles the output power of selected channels to drive speakers with higher output power. This means that speakers with varying output capacities can be powered simultaneously by the same amp. (Note that the number of available channels will be reduced by half.)

Construct a safe and scalable sound system based on Dante infrastructure. Audinate's Dante Domain Manager is network administration software that provides user authentication and role-based security settings. Dante Device Lock prevents a third party from modifying Dante settings, enhancing security in environments such as concert halls where an outside operator is expected to operate the system or bring in equipment. Meanwhile AES67 audio network interconnection standard allows connection to audio networks such as Ravenna, Q-LAN, or Livewire for secure, flexible scalability.

Automatic protection functions are an essential part of XMV, ensuring peak performance and reliable operation. XMV features powerful, intelligent protection functions that can deliver the assurance of long product life and consistent performance.

Source Select allows you to individually select input sources for each channel. It is possible to mix digital connections and analog connections for each input channel of an XMV. Backup Mode and Override Mode provide redundant functions to match the situation. In Backup Mode, XMV can detect an incoming pilot tone from the digital input and automatically switch to the analog input when the pilot tone is interrupted due to a problem from the input device. If the original input source is recovered, it will be able to return automatically to the digital input. In Override Mode, when voice input from the analog input is detected, it is possible to switch input sources for a channel without interrupting the sound. This is ideal for providing a backup signal for applications such as emergency broadcasts and announcements.
