Sony XM-4ES 4 Channel Power Amplifier

Powerful sound with astonishing clarity: Sony's expertise and long years of engineering experience with digital amplifiers have made it possible to realise a compact and powerful amplifier, with uncompromising sound quality.

Optimised power blocks: To reproduce powerful and clean low end, 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.

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.

Sturdily built structures: The bottom plate with 1.2 mm thickness and its updated cross-bracing press design improves chassis rigidity at approximately 50%, reducing the resonance and shifting the resonance peak out of the vehicle's harsh vibration frequency band while improving damping performance dramatically.

Clear labels and values:  The redesigned control panel features logical placements with easy-to-understand correlation, and updated graphics.
