Louder. Clearer. Smarter. The Alto Professional TS412 is part of the reimagined TS4 Series—an evolution of the TrueSonic legacy, offering more power, better clarity, and intelligent features tailored for modern performers. With an impressive 2500 watts of peak power delivered through a 12-inch woofer and 1.4-inch compression driver, the TS412 provides bold, full-range sound that excels in any environment—whether for vocals, DJ sets, or live music. Its compact, lightweight design ensures easy transport and setup, while the durable construction makes it ideal for both mobile gigs and permanent installations.

Designed for maximum flexibility and control, the TS412 includes built-in Bluetooth streaming and True Wireless Stereo (TWS) linking, allowing you to stream and pair speakers wirelessly for true stereo sound—no cables needed. Paired with the free Alto App for iOS and Android, users can remotely control levels, switch between DSP modes, create custom EQ curves, select subwoofer size, and manage stereo linking—all from anywhere in the venue. Your favorite settings can even be stored directly on the speaker for instant, hassle-free recall at any show.

A true plug-and-play solution, the TS412 features a 3-channel mixer with two Mic/Line combo inputs and a dedicated Bluetooth channel. The XLR/TRS combo jacks accommodate everything from microphones and instruments to playback devices, with no external mixer required. Onboard DSP presets allow for instant optimization for speech, music, or live performance, while the fanless Class D amplifier keeps things quiet and efficient. With versatile mounting options—freestanding, pole-mounted, wedge monitor, or flown—the TS412 adapts to any setup and delivers clean, powerful sound with professional control at your fingertips.
