Active Loudspeaker

The TS412 is a powered speaker in the brand new TrueSonic 4 series, delivering up to 2500 Watts Max! Following on from the success of the TS3 series, Alto is revisiting its now classic models and bringing them up to date. The TS4 speakers now feature Bluetooth connectivity, so you can stream your favourite playlists from your smartphone, tablet or laptop, as well as remotely controlling the powerful DSP added to them!

ARTICLE N° 84763
With their DSP system and integrated Bluetooth module, TrueSonic 4 speakers allow you to fine-tune the final acoustic performance with great precision, using the "Custom via App" DSP mode and the free Alto App.

Available for Android and iOS, this app lets you remotely control Bluetooth channel level, Speaker Use modes, custom 6-band EQ and subwoofer size selection.

In addition, the True Wireless stereo link, which allows you to stream audio content to 2 TS4 speakers in perfect stereo, all wirelessly, can be configured remotely via the app, saving you time during installation.

These speakers feature a lightweight chassis with a sleek design and a format that allows it to be used in a wide range of situations: freestanding, in a footwell return, mounted on a coupling bar or suspended thanks to the integrated anchor points.

Agréablement surprise par la marque: bonne puissance et prise en main facile. Le son est bon. A voir à l'usage. Bemol sur la portabilité : des roulettes auraient été bienvenues
