The Yamaha XMV4280 power amplifier 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. Installed sound applications often demand both high and low impedance connectivity in the same venue, requiring separate, dedicated amplifiers or an external transformer.
