Yamaha 8 Channel Amplifier 250 Watt XMV8140D

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.N/AN/AHigh impedance and low impedance or bothN/AN/AInstalled 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.N/AThe details of how many VXS/VXC speakers can be driven from an XMV amplifier channel are shown in FAQ.N/AN/ANew Double Power ModeN/AN/AThe 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.N/AN/ASelectable input formats for a wider range of applicationsN/AN/AXMV 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.N/AN/AA perfect match for the MTX SeriesN/AN/AWhen XMV power amplifiers are used in systems 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.N/AN/ABest installation amp ever?N/AN/AXMV amplifiers feature 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 lowimpedance operation can mean excessive energy loss so by automatically switching to a lower voltage drive efficiency is improved
