Engineered for Audio Excellence
The Sony XM-4ES 4-channel amplifier is meticulously engineered to elevate every track, including High-Resolution Audio files. Premium circuit components synergise to achieve optimal efficiency and precise sound reproduction, ensuring that every journey is accompanied by the perfect soundtrack.
Powerful Sound with Crystal Clarity
Drawing on Sony's expertise and extensive engineering experience, the XM-4ES delivers powerful and clear audio without compromise.
Optimised Power Blocks
The power supply block is meticulously designed to facilitate low-noise, highly efficient electric power transmission. The inclusion of a DC converter with a toroidal core transformer reduces electro-magnetic interference, ensuring pristine sound reproduction. Each channel block and class-D amplification feature their own ground circuitry to minimise signal interference, allowing delicate ultra-high-frequency sound reproduction.
The 1.2mm-thick bottom plate, coupled with an updated cross-bracing press design, enhances chassis rigidity by approximately 50%. This design reduces resonance and shifts the resonance peak away from the vehicle's vibration frequency band, significantly improving damping performance.
