XM-4ES | Mobile ES™ 4-Channel Power Amplifier
Enjoy dynamic sound with an output power of 100 W x 4 (330 W x 2 bridged) RMS at 4 ohms / 165 W x 4 RMS at 2 ohms. The highly efficient class-D amplifier provides a variety of speaker configurations to suit any car and impress any audio enthusiast.
Listen to the subtlest nuances of studio-quality sound in higher-than-CD quality with High-Resolution Audio. Feel as if the artist was performing right in front of you.
The XM-4ES 4-channel amplifier is engineered to enhance every track—including High-Resolution Audio files. A range of premium circuit components work together for ultimate efficiency and pitch-perfect sound reproduction, giving every road trip the soundtrack it deserves.
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.
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, minimizing any signal interference.
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.
The sturdy aluminum frame and solid (1.2 mm) bottom plate reduce vibration and wick away heat, resulting in low resonance and a tightly controlled musical performance.
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.
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.
The redesigned control panel features logical placements with easy-to-understand correlation and updated graphics.
Easily integrate the XM-4ES into your system with clear input and output settings.
Filter parameters are grouped for seamless sound tuning.
The clear, high-contrast labels make adjustment quick and easy, so you can get your system sounding great, faster.
The new signal summing feature combines filtered audio signals from modern factory car audio systems, such as those for the separate tweeter, woofer and subwoofer, accurately amplifying the full stereo frequency range easily. And you can even send the consolidated line-level signal onto other mono or stereo amps in the chain, allowing for flexible installation in various types of vehicles and audio system setups.
