Yamaha XMV8140-D - 70 Volt Dante Enabled Commercial Multi-Channel Power Amplifier 8 x 140 watts

Yamaha XMV8140-D - 70 Volt Dante Enabled Commercial Multi-Channel Power Amplififier 8 x 140 watts The Yamaha Dante amplifier XMV8140D is a Multi-channel Power Amplifier that has a unique features of eight channels that can operate in both high-impedance (70V/100V line) or low-impedance (4Ω/8Ω) modes at the same instant, excluding the need for additional equipment, as well as streamlining the installation process. Yamaha Dante amplifier XMV8140D 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. The newly-developed “Double Power mode” doubles the amplifier output of each channel when low-impedance connections are used.The Yamaha Dante amplifier XMV8140D features Dante technology as a protocol, the function is to transmit audio signals. Dante is a network protocol developed by Audinate. It is designed to deliver multi-channel audio signals at various sampling and bit rates, as well as device control signals over a Giga-bit Ethernet (GbE) network. Dante also offers the following benefits: Yamaha Dante amplifier XMV8140D Product Highlights  It transmits up to 512 in/512 out, for a total 1024 channels (theoretically) of audio over a GbE network. Dante-enabled devices will automatically configure their network interfaces and find each other on the network. You can label Dante devices and their audio channels with names that make sense to you. Dante uses high accuracy network synchronization standards to achieve sample-accurate playback with extremely low latency and jitter. Dante supports redundant connections via primary and secondary circuits to defend against unforeseen difficulties. Connecting a Dante-enabled device to a computer over Ethernet enables you to directly input or output audio signals without using any audio interface devices. A comprehensive line-up to power your sound solution. 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.
