Where the Alto TS3 Series exceeded expectations, the Alto TS4 Series completely redefines them.
The TS4 Series builds on Alto's legacy best-selling TrueSonic speakers with more power, clearer sound and advanced Bluetooth features like streaming, speaker pairing and app control. The new series is compact, lightweight, built for reliability and makes it easy to deliver great live sound at any event.
The TS415 is a 15-inch 2-way active speaker that delivers 2500 watts of high power with clear, balanced sound. Whether you need powerful vocals or a thumping bass performance for a DJ set, this speaker will impress with loud, clear, room-filling sound for any application.
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 favourite Custom EQ setting directly to the TS4 for easy recall when you need it.
Easy Bluetooth streaming and speaker pairing.
The Alto TS415 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.
Versatile and reliable
From the high-quality drivers to the fanless Class D amplifiers, every aspect of the TS4 Series is designed for maximum reliability, whether for mobile gigs and performances or fixed installations. Each speaker features a lightweight, sleek black-box design that can be used depending on the application - freestanding, as a wedge monitor, pole-mounted or suspended via the integrated flying points.
FREE Alto App for remote configuration and control.
The free Alto App, available for both Android and iOS, provides convenient remote control of Bluetooth levels, speaker usage modes, custom EQ and sub-size selection. In addition, the True Wireless Stereo connection can be configured via the app to save time during setup.
