Alto Professional TS415 Active Loudspeaker

The completely new line of professional loudspeakers Alto Professional TS4 brings excellent solutions for installation and mobility. The newly designed 2500 W bi-amp amplifier provides truly high-performance sound without compromise or limitation. Their elegant design, light but durable construction, control via Android/iOS app, playback via Bluetooth and connectivity exceed all expectations.

Building on the legacy of TrueSonic's best-selling Alto speakers, the TS4 series delivers increased performance, clearer sound and advanced Bluetooth features, including streaming, speaker linking and mobile app control. Compact, lightweight and designed for reliability - the new TS4 range simply delivers great sound suitable for any type of event.

Whether you need powerful vocal PA or bass performance for DJs, the TS4 speakers deliver loud and clear room-filling sound for any application. With a 15-inch woofer and a 1.4-inch compression driver, the TS415 delivers 2500W of peak power and sound clarity in equal measure.

The Alto app, available for free on both Android and iOS, provides convenient remote control of Bluetooth levels, speaker modes, custom equalizer and Subwoofer selection. Plus, the True Wireless Stereo connection can be configured remotely via the app to save time on setup.

Each TS4 is equipped with an integrated 3-channel mixer with two Mic/Line input channels and an independent Bluetooth channel. The Mic/Line channels feature combination XLR/TRS connectors and can be used with microphones, instruments and line-level signals without the need for additional hardware or modification. Just connect directly to the back panel.

The TS4's built-in Bluetooth connectivity is ideal for high-performance streaming and makes it easy to pair with a laptop, phone or tablet and start playing music. With True Wireless Stereo, you can stream Bluetooth audio to two TS4 speakers in perfect stereo without the need for any cables.
 
The TS4's three preset "Speaker Use" modes allow you to optimize the speaker for any application, so you get great sound every time at the push of a button. For even more control over your sound, you can configure your own equalizer in the Alto app and adjust settings remotely from any listening position. You can even save your favorite custom EQ settings right into the TS4 for easy recall at any time.

From high-quality drivers to fanless Class-D amplifiers, every aspect of the TS4 series has been designed for superior reliability, whether used for mobile gigs and performances or for fixed installation. Each speaker has a lightweight black design that can be used as the application demands – freestanding, as a wedge monitor, pole mounted or suspended via integrated suspension points.
