Alto TS412 Description

The Alto TS412 is the ideal powered speaker for medium to large events, live performances, and mobile DJ setups. With its 2500W peak Class D amplifier and carefully tuned 2-way system, the TS412 pushes out clear, deep audio with minimal distortion—even at high volumes. It features a 12-inch woofer with a 2.5-inch voice coil for enhanced low-end, and a 1-inch ceramic compression driver for detailed highs. Connectivity is simple and versatile with the integrated 3-channel mixer. Two combo XLR/TRS inputs handle mics, instruments, or line-level sources, while Bluetooth 5.0 enables wireless audio streaming and True Wireless Stereo linking with another TS4 unit—no cables required. With the free Alto App for iOS and Android, users can control DSP settings remotely, including speaker use modes, subwoofer size, Bluetooth volume, and custom EQ configurations. This gives you complete control over your sound, even from the middle of the crowd. Designed for flexibility and durability, the TS412 can be pole-mounted, angled as a wedge monitor, or flown via M10 suspension points. The fanless design ensures silent operation, and electronic protections help prevent thermal and signal overload during high-demand performances.
