Yamaha XMV8280- 70 Volt Commercial Multi Channel Power Amplifier 8 x 280 watts

Yamaha XMV8280 - 70 Volt Commercial Multi Channel Power Amplifier 8 x 280 watts

The best thing in Yamaha  XMV8280 - 70 Volt power amplifier is it can operate in both high-impedance (70V/100V line) or low-impedance (4Ω/8Ω) modes at the same moment, excluding the need for additional equipment, as well as streamlining the installation process. Installed sound applications often demand both high and low impedance connectivity in the same venue, requiring separate, dedicated amplifiers or an external transformer. 

Yamaha  XMV8280 - 70 Volt power amplifier also enable 70V and 100V or both

The Yamaha  XMV8280 - 70 Volt power amplifier 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. High impedance operation often requires the use of two combined channels in bridge mode, but with Yamaha  XMV8280 - 70 Volt amplifier, 70V or 100V mode can be assigned to every pair of channels without affecting the number of available output channels.

Protection features for more reliable operation

The essential part of Yamaha XMV8280 - 70 Volt is the Automatic functions that ensuring the peak performance and reliable operation in less than ideal situations. Low load impedance, overcurrent, and overheating can all damage vital amplifier components and threaten their ability to function effectively. To prevent these dangerous hazards, the Yamaha XMV8280 - 70 Volt power amplifier features powerful, intelligent protection functions that can deliver the assurance of long product life and consistent performance.
