True front sound entertainment
The HDSX TV Sound Optimizer adapts TV, cinema, streaming or gaming sound to playback through an external sound system.

You’ve never heard your external sound system sound so balanced and articulate.

Thousands of customers are already convinced

For one year now, the HDSX TV Sound Optimizer has been conquering households in Germany. “Thanks for the engineering achievement!” or “An absolute buy recommendation!” are regular feedback in our reviews.

Test reports regularly award outstanding ratings to the HDSX TV Sound Optimizer:

satvision, issue 9/2022:
‘The special feature is…that even fluctuations or volume differences, which naturally occur during action-packed scenes, are reduced to a perfect level, but without cutting certain frequency ranges, as happens, for example, with the night mode of many sound systems.’

HDTV Magazine issue 3/2021:
‘Tonality changes significantly with the interposition of the HDSX-box: the focus is on speech intelligibility and ‘hear-through’. Thanks to the HDSX-box it is possible to equalize strongly fluctuating volume levels without nipping the general liveliness of the recording in the bud.’

Viewed various blockbusters. Very balanced sound. During the initial installation, small problems with the required settings on the TV. The Kronoton team solved my problems very quickly...Super.
