The Yamaha XDA-AMP5400RK installation power amplifier extends speaker coverage in professional multi-room audio systems when used with the Yamaha XDA-QS5400RK. It features 8 channels of Class D amplification, Bridge (BTL) mode and support for speakers with a minimum impedance of 4 Ω. Its 4 independent audio buses and included jumpers allow for flexible speaker configurations.

Its circuitry is designed to eliminate ground loops and unwanted hum. Powering it on and off can be synchronized with the XDA-QS5400RK via the Trigger inputs and outputs. The 1U metal chassis is suitable for rack mounting, and the package includes removable rack brackets and a front panel.
