Just plug straight into the rear panel and you’re up and running.
Simple Bluetooth Streaming & Speaker Linking
The ideal high-powered streaming solution, TS4’s built-in Bluetooth connectivity makes it easy to pair your laptop, phone or tablet and get the music pumping in no time at all.
DSP Modes for the best sound in every application
TS4’s three preset “Speaker Use” modes let you optimize the speaker for any application, so you’ll get great sound every time at the touch of a button. For even more control over your sound, you can configure a Custom EQ within the Alto App and remote adjust the settings from any listening point in the venue. You can even save your favorite Custom EQ setting direct to the TS4 for easy recall whenever you need it.
