Yamaha XMV4140 70 Volt Commercial Multi-Channel Power Amplifier 4 x 140 watts

Yamaha XMV4140 70 Volt Commercial Multi Channel Power Amplifier 4 x 140 watts

The Yamaha XMV4140 power amplifier has two unique features, you can choose high-impedance (70V/100V line) or low impedance (4Ω/8Ω) modes simulataneously, 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. 

The Yamaha XMV4140 power amplifier 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. High impedance operation often requires the use of two combined channels in bridge mode, but with Yamaha XMV4140 amplifier, 70V or 100V mode can be assigned to every pair of channels without affecting the number of available output channels.

Yamaha XMV4140 Product Highlights

• Four-channel power amplifier that can operate in both high-impedance (70V/100V line) or low-impedance (4Ω/8Ω) modes simultaneously.
• 70V or 100V mode can be assigned to every pair of channels without affecting the number of available output channels
• The newly developed Double Power Mode function effectively doubles the output power of selected channels
• Equipped with YDIF digital audio format for simple and fast system configuration
  • 4x 140W at 8Ω/4Ω
  • 4x 125W at 100V/70V lines
