Yamaha XMV4140 Power Amplifier

Yamaha XMV4140 Power Amplifier Overview:

XMV Series multi-channel power amplifiers combine Class-D efficiency with features designed specifically to benefit commercial installation sound systems. The Series is comprised of 8 different models with varying output power capabilities and flexible in/out connectivity to accommodate a wide range of installation environments.

• 4x 140W at 8/4
• 4x 125W at 100V/70V lines
• 2x 280W at Double Power Mode (8/4)

Features:
High impedance and low impedance or both

Installed sound applications often demand both high and low impedance connectivity in the same venue, requiring separate, dedicated amplifiers or an external transformer. XMV power amplifiers, however, can operate in both high-impedance (70V/100V line) or low-impedance (4/8) modes simultaneously, eliminating the need for additional equipment, as well as streamlining the installation process. XMV power amplifiers also enable 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 amplifiers, 70V or 100V mode can be assigned to every pair of channels without affecting the number of available output channels.

New Double Power Mode
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.*The number of channels that can be used will be reduced to half

Selectable input formats for a wider range of applications
XMV amplifiers come equipped with either the newly developed YDIF digital audio format, or Audinates digital audio network Dante. 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.

Support for Dante Domain Manager, AES67 and Dante Device Lock
Supports the “Dante Domain Manager” audio network interconnectivity standard (update to version 3.31). Audinate Corporation’s “Dante Domain Manager” is now supported. Audinate Corporation’s “Dante Domain Manager” is network administration software that provides user authentication and role-based security settings. Now you can construct a safe and scalable sound system based on Dante infrastructure.

A perfect match for the MTX Series
When XMV power amplifiers are used in systems with MTX/MRX series processors, settings such as the mute on/off or attenuator changes can be set via computer using the MTX-MRX Editor software application. YDIF and Dante ports make system configuration simple and fast with instant connectivity and flexible parameter control.
