Built-in 3-channel mixer

Each TS4 has a built-in 3-channel mixer with two mic/line input channels and a dedicated Bluetooth channel. The mic/line channels feature XLR/TRS combo jacks and can be used with microphones, instruments, and line-level signals without requiring additional Hardware or adjustments. Just plug the microphone into the rear panel and you're ready to go.

DSP modes for the best sound in any application

The TS4 Series' three preset "Speaker Use" modes let you optimize the speaker for any application, so you always get great sound at the touch of a button. For even more control over your sound, you can configure a custom EQ in the Alto app and control the settings remotely from any listening position. You can even save your favorite Custom EQ setting directly to the TS4 for easy recall when you need it.

Easy Bluetooth Streaming and Speaker Pairing

The Alto TS410 is an ideal high-power streaming solution. With built-in Bluetooth connectivity, you can easily pair your laptop, phone or tablet and enjoy music with the best sound in no time. With the True Wireless Stereo feature, you can stream Bluetooth audio signals in perfect stereo to two TS4 speakers without additional cables.
