Product Description

OUND DIGITAL EVOX 400.4 AMPLIFIER : Dynamic Thermal Dissipation

A system that provides a faster heat exchange with the environment, increasing the efficiency of the amplifier resulting in lower levels of distortion during long working periods. Reduced Size The technology used in the SounDigital products brings both high performance and power in a small chassis, providing installation solutions for vehicles with limited space and finishing.

Dynamic Thermal Recovery DTR

The DTR is a dynamic thermal recovery system which always maintains a high efficiency of the amplifier by accelerating the thermal exchange of electronic components with the heatsink.

Aluminum heatsink Conductive copper layer Electronic component Vibration Absorption Device SounDigital added a new device to the EVO X products which act like springs, reducing the impact of vibration on the electronic circuit board, thereby increasing the life and reliability of the amplifiers.
