Yamaha XMV4140-D 4-Channel Power Amplifier

XMV power amplifiers 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 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.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.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. AES67 audio network interconnection standard is supported by this amplifier. This allows connection via AES67 to audio networks such as Ravenna, Q-LAN, or Livewire, increasing the expandability of the system. Also supported is Dante Device Lock, which prevents a third party from modifying Dante settings. This can increase system security in environments such as concert halls where an outside operator is expected to operate the system or bring in equipment.
