Alto TS408 Powered 8 Inch PA Speaker 2000W with Bluetooth

Where TS3 exceeded expectations, the Alto TS408 redefines them completely. Above all, the TS408 delivers increased power, clearer sound, and advanced Bluetooth functions. Specifically, this includes streaming, speaker linking, and App control. Compact, lightweight, and designed for reliability, the new TS408 Series makes it simple to get great live sound.

True Sonic Power

Whether you need a powerful vocal PA or club-shaking bass performance for a DJ set, the TS408 speaker delivers! Particularly, with an 8-inch woofer, and a 1.4-inch compression driver, TS408 delivers 2000W of class-leading power and clarity.

FREE Alto App for Remote Configuration and Control

Additionally, 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. Furthermore, True Wireless Stereo linking can be configured remotely via the app to save time during setup.

Built-In 3-Channel Mixer

The TS408 features an integrated 3-channel mixer, with two Mic/Line input channels and a dedicated Bluetooth channel. Similarly, 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

TS408’s built-in Bluetooth connectivity makes it easy to pair your laptop, phone or table. You will be able to get the music pumping in no time at all. Also, with the True Wireless Stereo function, you can stream Bluetooth audio to two TS408 speakers in perfect stereo without the need for any cables.

TS408 DSP Modes for the Best Sound in Every Application

TS408’s three preset “Speaker Use” modes let you optimize the speaker for any application. Consequently, you’ll get great sound every time at the touch of a button. For more control over your sound, configure a Custom EQ within the Alto App. Afterwards, remote adjust the settings from any listening point. You can even save your favourite Custom EQ setting direct to the TS408 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 TS408 has been designed for superb reliability, whether used for mobile gigs and performances or fixed installation. Additionally, 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.
