Alto Professional Truesonic TS4 Series Active PA Speakers

Building on the huge success of Alto Professional’s TS3 Series, the new TS4s deliver increased power (up to 2500W on TS412 and TS415 models); “Speaker Use” DSP Modes to get great sound for any application; and Bluetooth con-nectivity, linking and control via the free Alto App.

Where TS3 exceeded expectations, TS4 redefines them completely.

Building on the legacy of our best-selling TrueSonic speakers, the TS4 Series delivers increased power, clearer sound, and advanced Bluetooth functions including streaming, speaker linking, and App control.

Compact, lightweight, and designed for reliability, the new TS4 Series makes it simple to get great live sound at every event.

Whether you need a powerful vocal PA or club-shaking bass performance for a DJ set, TS4 speakers deliver loud, clear, room-filling sound for any application.

Available free for both Android and iOS, the Alto App gives hands-on remote control over Bluetooth levels, Speaker Use Modes, Custom EQ and Sub Size selection.  Further, True Wireless Stereo linking can be configured remotely via the app to save time during setup.

Every TS4 features an integrated 3-channel mixer, with two Mic/Line input channels and a dedicated Bluetooth channel. The Mic/Line channels feature XLR/TRS combo jacks and can be used with microphones, instruments, and line-level signals without the need for additional hardware or adjustment. Just plug straight into the rear panel and you’re up and running.
