High-Power Amplifier with Remarkable Clarity

Built on decades of Sony’s proven digital amplifier innovation, the XM-4ES delivers robust output and exceptionally clean audio in a compact, well-engineered chassis. This versatile 4-channel amp is specifically designed for discerning audiophiles seeking dynamic, high-clarity sound without compromise.

Low-Noise, High-Efficiency Power Block Design

The optimized power supply block features a toroidal-core transformer for minimal electromagnetic interference and enhanced electric power transmission. Each channel and the class-D amp circuitry are ground-isolated, effectively reducing signal interference and preserving sound purity, especially in high-frequency ranges.

Premium Components for Precise, Deep Bass

The XM-4ES utilizes carefully upgraded inductors with premium oxygen-free copper (OFC) wire to reduce resistance and significantly enhance overall tonal clarity. High-capacity electrolytic capacitors deliver tight, responsive bass performance for an impactful and truly immersive audio experience.

Durable, High-Performance Speaker Terminals

Engineered for secure and exceptionally high-quality connections, the premium Hex-key screw terminals support bare wire or ferrules (up to AWG #8). These heavy-duty, professional-grade connectors ensure superior signal flow and safe installation in demanding high-performance systems.

User-Friendly Controls and Connection Layout

With intuitive control placement and logically grouped connections, the XM-4ES makes setup and tuning remarkably effortless and user-friendly. The thoughtfully redesigned layout simplifies even the most complex adjustments, making it extremely easy to optimize your sound system on the go with minimal hassle.

Reinforced Chassis for Vibration Resistance

A 1.2 mm-thick bottom plate and cross-bracing press design enhance the chassis rigidity by approximately 50%. This dramatically reduces unwanted resonance, shifting vibrations out of the audible range for cleaner, undistorted playback in any driving condition.

Signal Summing for Factory System Integration

Easily upgrade your factory sound system with the signal summing feature, which combines tweeter, woofer, and subwoofer signals into a full-range stereo signal. You can also pass this signal to other amplifiers, offering maximum flexibility for multi-amp installations across vehicle types.

Redesigned Control Panel for Easy Operation

The updated control interface features clearly labeled, logically arranged settings, making adjustments straightforward. Enhanced graphics and intuitive layout make fine-tuning your system easier than ever.
