XMV4140

Power Amplifier

Overview

The Yamaha  XMV4140 power amplifier 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. Installed sound applications often demand both high and low impedance connectivity in the same venue, requiring separate, dedicated amplifiers or an external transformer. 

Features

• Equipped with the newly developed YDIF digital audio format for easy setup

• 70V or 100V mode can be assigned to every pair of channels

• Powerful, intelligent protection features for more reliable operation

Also enables both 70V and 100V operation

YamahaXMV-features The XMV4140 power amplifier 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 XMV4140 amplifier, 70V or 100V mode can be assigned to every pair of channels without affecting the number of available output channels.

New "Double Power Mode"

YamahaXMV-features The newly 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.

A perfect match for the MTX Series

YamahaXMV-features The XMV4140 is used in system with MTX series processors, settings such as the mute on/off or attenuator changes can be set via computer using the MTX Editor software application. YDIF and Dante ports make system configuration simple and fast with instant connectivity and flexible parameter control.

Selectable input formats for a wider range of applications

YamahaXMV-features The XMV4140 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 XMV4140 amplifier features an innovative, 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.

Protection features for more reliable operation

YamahaXMV-features 5 Automatic protection functions are an essential part of the XMV4140 design, ensuring peak performance and reliable operation in less than ideal situations. Low load impedance, overcurrent, and overheating can all damage vital amplifier components and threaten their ability to function effectively. To combat these hazards, XMV4140 power amplifiers feature powerful, intelligent protection functions that can deliver the assurance of long product life and consistent performance.

External control via Ethernet

The XMV4140 is equipped with a Network port that allows direct control from controllers such as AMX/Crestron.
