  • Dynamic Power Sharing Allocates Total Output Across Active Channels For Efficient Multi-Zone Deployment
  • Integrated Matrix Router And Speaker Processing Eliminate External DSP Requirements In Simpler Installations
  • Per-Channel Hi-Z And Lo-Z Mode Selection Supports Mixed Load Configurations Within Single Chassis
  • ProVisionaire Design Software Enables Unified System Configuration And Monitoring Across Installation
  • Front-Panel LCD And Controls Provide Direct Access To Gain Adjustment And Operational Status
  • Redundant Dante Network Topology With AES67 Compatibility Ensures Reliable Audio Transport
  • Factory Speaker Presets For Yamaha Passive Loudspeakers Accelerate System Commissioning

The Yamaha XMS Series delivers intelligent amplification for installed sound systems where flexible channel distribution and onboard signal processing eliminate the need for external DSP in many commercial audio installations. Dynamic power sharing allocates the full 1200W pool across active channels, maximizing available headroom while reducing amplifier count in multi-zone designs. Part of Yamaha's Commercial Installation Solutions Ecosystem, XMS amplifiers integrate with DME Series processors for larger systems or operate standalone with the built-in 4×4 matrix router, 16-band parametric EQ, and comprehensive speaker processing.

Class D topology delivers consistent performance in both Lo-Z and Hi-Z modes with per-channel configuration, supporting 4Ω, 8Ω, 70V, and 100V distributed line applications within a single chassis. Front-panel LCD and control interface enable system monitoring and gain adjustment without software access. Dante connectivity supports redundant and daisy-chain topologies with AES67 compatibility, while ProVisionaire Design software provides unified configuration across the entire installation from a single interface. Suited for corporate boardrooms, hospitality venues, education facilities, and retail spaces requiring reliable amplification with intelligent routing capabilities.
