Powerful sound with astonishing clarity
Sony’s expertise and long years of engineering experience with digital amplifiers has made it possible to realize a compact and powerful amplifier, with uncompromising sound quality.
Optimized power blocks
The power supply block is optimally designed for low-noise, highly efficient electric power transmission, where the DC converter with a toroidal core transformer is chosen for less electro-magnetic interference. To reproduce delicate ultra-high-frequency sound, each channel block and the class-D amplification are all isolated with their own ground circuitry, minimising any signal interference.
Select components for superior sound
The upgraded inductors with OFC wires are selected for lower internal resistance and improved sound character, while the high-capacity electrolytic capacitors contribute to precise and responsive bass.
Sturdily built structures
The sturdy aluminium frame and solid (1.2mm) bottom plate reduce vibration and wick away heat, resulting in low resonance and a tightly controlled musical performance.

Mobile ES amplifier
Enhanced logical control and connection placement
Controls for adjustments, and placement of connections, are logically placed for easy understanding and use. The carefully considered layout ensures both intuitive operation and installation simplicity.
High-quality speaker terminal
The speaker terminal features Hex-key screws, providing a durable method of tightening the wire connections while accepting bare wire or wire ferrules (up to AWG #8) for superior electrical performance and high-quality sound, and safe connection.
Clear labels and values
The redesigned control panel features logical placements with easy-to-understand correlation, and updated graphics.
Input / output adjustments
Easily integrate the XM-4ES into your system with clear input and output settings.
Filter / range adjustments
Filter parameters are grouped for seamless sound tuning.
Easy operation
The clear, high contrast labels makes adjustment quick and easy, so you can get your system sounding great faster.
Signal summing for seamless connection to factory audio
The new input selector can combine stereo audio signals into a monaural signal, before filtering to low-end. And you can even send the consolidated or passing through line-level signal onto other amps in the chain, allowing for flexible installation in various types of vehicles and audio system setups.
