Consistent volume

No more commercials that are too loud, dialogues that are too quiet and constant readjustment via remote control. The cutting-edge technologies HDSX.volume and HDSX.speech optimise the sound in real time and in maximum sound quality.

Clear dialogue

Intelligent volume control in real time. Dialogue is intelligible throughout, whether it’s a heavy action scene or a quiet love scene. All dialogues are consistently intelligible.

Perfect integration

Whether it’s a soundbar, mobile speaker or hi-fi system: use the speaker system you have at home flexibly and simply plug the HDSX TV Sound Optimizer between the TV and the speaker system.

Uncompressed sound quality

Optical Toslink digital connections guarantee the highest sound quality thanks to the PCM stereo audio format.

Thoughtful design

Carefully designed for the perfect TV listening experience. Just the size of a palm, the HDSX TV Sound Optimizer can be mounted directly behind your TV. It is invisibly powered by the TV’s energy-efficient USB port.

Enveloped in sound.
Immersive and object-based audio formats, such as Virtual Dolby Atmos, are also optimized in real time. You are in the middle of the action and understand every word without volume fluctuations.
