The Alto TS4 Series represents a quantum leap in powered speaker technology, delivering 2000W of pure sonic power that transforms any venue into an audio powerhouse. Building upon the acclaimed TrueSonic legacy, these speakers combine increased output, crystal-clear sound reproduction, and cutting-edge Bluetooth functionality to create the ultimate live sound solution. The compact yet robust design ensures reliable performance across diverse applications, from intimate vocal presentations to bass-heavy DJ sets that demand room-shaking low-end response.
Advanced connectivity sets the TS4 apart from conventional powered speakers, featuring comprehensive Bluetooth streaming capabilities and True Wireless Stereo linking that eliminates cable clutter. The free Alto App provides complete remote control over EQ settings, speaker modes, and Bluetooth levels from any iOS or Android device. An integrated 3-channel mixer with dual XLR/TRS combo inputs handles microphones, instruments, and line signals seamlessly, while four preset Speaker Use modes optimise performance for specific applications at the touch of a button.
Professional-grade components ensure exceptional reliability and sound quality, including an 8" driver with high-temperature voice coil and 1" ceramic compression driver. The fanless Class D amplification system runs cooler and quieter than traditional designs, delivering consistent performance during extended use. Versatile mounting options accommodate pole-mounting, wedge monitoring, or permanent installation via integrated M6 suspension points, making the TS4 Series equally suited to mobile performers and fixed installations.
