TrueSonic TS4 from Alto Professional

Louder. Clearer. Smarter.

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.

True Sonic Power

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.

With a 15-inch woofer, and a 1.4-inch compression driver, TS415 delivers 2500W of class-leading power and clarity in equal measure.

FREE Alto App for remote configuration and control

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. 

Built-In 3-channel mixer

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.

Simple Bluetooth Streaming & Speaker Linking

The ideal high-powered streaming solution, TS4’s built-in Bluetooth connectivity makes it easy to pair your laptop, phone or tablet and

get the music pumping in no time at all.

With the True Wireless Stereo function you can stream Bluetooth audio to two TS4 speakers in perfect stereo without the need for any

cables.

DSP Modes for the best sound in every application

TS4’s three preset “Speaker Use” modes let you optimize the speaker for any application, so you’ll get great sound every time at the touch

of a button. For even more control over your sound, you can configure a Custom EQ within the Alto App and remote adjust the settings

from any listening point in the venue. You can even save your favourite Custom EQ setting direct to the TS4 for easy recall whenever you

need it. 

Versatile and Reliable

From the high-quality drivers to the fanless class D amplifiers, every aspect of the TS4 Series has been designed for superb reliability,

whether used for mobile gigs and performances or fixed installation.

Each speaker features a lightweight, sleek, black box design that can be used as the application demands - freestanding, as a wedge

monitor, pole-mounted or suspended via the integrated suspension points.
