INFORMACIJA

Effective upgrade for classic OEM sound systems
The UP 4DSP expands the MATCH UP range with a 4-channel amplifier and integrated 5-channel DSP: the ideal solution for vehicles with simple 2- or 4-channel factory radios where a clear audible sound quality improvement is desired – without the complexity of larger multi-channel amplifiers. It is designed to significantly improve factory sound systems, ensuring clean and inconspicuous integration into the vehicle.
With optional plug-and-play cables and a smart 4-channel high-level input with ADEP.3, the UP 4DSP seamlessly integrates into modern OEM architectures. Its compact size and high efficiency make it an excellent choice for daily drivers, rental cars, or installations with very limited space – anywhere a high-quality, space-saving, and fully everyday-ready upgrade is needed.
