Alto TS415 Description

The Alto TS415 pushes the limits of portable sound reinforcement with 2500 watts of Class D amplification driving a 15-inch low-frequency driver and a 1-inch ceramic high-frequency driver. Designed for larger venues and high-energy events, it delivers up to 135dB of peak SPL and a deep frequency response down to 33Hz. The built-in 3-channel mixer supports two combo XLR/TRS inputs and a dedicated Bluetooth channel. True Wireless Stereo (TWS) lets you link two TS415 units without cables for a wide, immersive stereo field—perfect for streaming music or full-range playback. Whether you’re plugging in microphones, instruments, or streaming tracks from your phone, setup is fast and intuitive. The free Alto App for iOS and Android unlocks remote control of DSP functions, including custom EQ, subwoofer size selection, and speaker use presets. This flexibility makes it easy to tune the system to any space without leaving your mix position. Constructed with a molded enclosure and metal grille, the TS415 is durable and ready for stage use. It can be pole-mounted, angled as a wedge monitor, or suspended using integrated M10 points—perfect for both mobile and fixed installs. A fanless design ensures quiet operation, while built-in protection keeps your gear safe under stress.
