Yamaha XMV8140 70 Volt Commercial Multi Channel Power Amplifier 8 x 140 watts

The power amplifier of Yamaha XMV8140 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. Installed sounf applications often demand both high and low impedance connectivity in the same venue, requiring separate, dedicated amplifiers or an external transformer.

Also enables both 70V and 100V operation

The power amplifier of Yamaha XMV8140 can also enables both 70V and 100V operation for every pair of channels by easy selecting the preferred mode using the dip switches on the rear panel of the Yamaha XMV8140. High impedance operation often requires the use of two combined channels in bridge mode, but with Yamaha XMV8140 amplifier, 70V or 100V mode can be assigned to every pair of channels without affecting the number output channels.

Protection features for more reliable operation

There is an essential part of Yamaha XMV8140 design and that is the Automatic protection functions it ensure the peak performance and reliable operation in less than ideal situations. Low load impedance, overcurrent, and overheating can all damage vital parts of amplifier components and threaten their ability to function effectively. To prevent these dangerous hazards, The Yamaha XMV8140 power amplifier features a powerful and intelligent functions that can deliver the assurance of long product life and consistent performance.
