XMV4140

Sound installation applications often require both low and high impedance connections for the same event, requiring separate dedicated amplifiers or an external transformer. XMV amplifiers, on the other hand, are capable of operating in both high impedance (70V / 100V line) or low impedance (4O / 8O) modes simultaneously, eliminating the need for additional devices and streamlining the installation process. In addition, the XMV amplifiers allow 70V and 100V operation for each 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, the 70V or 100V modes can be assigned to each pair of channels without altering the number of available output channels.

The new Double Power Mode function effectively doubles the output power of the selected channels in order to drive speakers with higher output power. This means that speakers with variable output capabilities can be powered simultaneously from the same amplifier, adding flexibility to system design and configuration.
The XMV amplifiers feature both the new YDIF digital audio format and the Audinate Dante digital audio network. YDIF allows for easy setup thanks to Ethernet cables while Dante models can be used for larger events where long distance cabling is required.
Best installation amplifier ever?
The XMV amplifiers are equipped with an innovative patented circuit that improves the topology of the already highly efficient Class D circuits, bringing the efficiency level of the amplifiers output to 90%. This can be done automatically by adjusting the circuit to match the corresponding output voltage. In high impedance connections, both 70V and 100V operations can be achieved as the circuit is already capable of operating at these high voltages. However, using the same circuit with low impedance operations can result in excessive energy dispersion, so by automatically switching to a lower voltage drive, efficiency is significantly improved without sacrificing crucial aspects of an amplifier's performance such as for example, the containment of distortion levels to a minimum. The XMV amplifiers also feature a new power supply with Power Factor Correction, which ensures harmonic control and significantly decreases the amount of current, while maintaining the same output power level. This makes circuit protection systems less likely to shut down the system, while also eliminating the need for large, heavy cables or a larger, more powerful system.
