Alto Professional TS408 is a powered speaker with a 2000W peak power (RMS: 650W low, 350W high), covering a frequency range from 52Hz to 20kHz, and features three audio inputs with separate volume controls: two mic/line on Combo connectors and one wireless Bluetooth 5 with pairing buttons and a stereo link function. Max SPL: 130dB (peak), 127dB (continuous). DSP functions controllable via iOS and Android app.

Alto TS408: True Sonic Power

Whatever your amplification needs, the Alto Professional TS408 speaker offers an elegant and high-quality product, with a 2000W peak power, an 8” woofer and a 1” compression tweeter, respectively equipped with 2” (50mm) and 1.4” (35mm) voice coils and Class D amplified with 650W and 350W RMS. The frequency response ranges from 62Hz to 20kHz with a tolerance margin of +/-3 dB, extending down to 52Hz in the low frequencies with a tolerance of -10 dB.

Free Alto iOS and Android App  

Configure and control your Alto Professional TS408 powered speaker from your smartphone and tablet thanks to the dedicated App available for free for iOS and Android devices. In the application, you can configure the Bluetooth audio level, the speaker's mode of use, set your custom equalization (with a 6-band parametric EQ), and the high-pass filter that best suits the size of your eventual Subwoofer. Furthermore, you can configure the True Wireless Stereo Link directly in the app, thus minimizing setup times. A Type A USB port on the rear panel of the TS408 allows for charging/powering smartphones and tablets.

3-channel mixer integrated into the TS408

As in all models of the TS4 by Alto Professional series, the smallest TS408 also features an integrated 3-channel mixer: 2 mic/line on Combo connectors (accepts XLR or 1/4” TRS Jack) and one wireless Bluetooth 5 with buttons for Pairing and Stereo Link function. The Mic/Line selector on the combo inputs allows you to set the appropriate preamplification depending on the connected source. With the "Mix Out" XLR output, wired cascade connections are possible. You can therefore connect directly to your speaker and control the volume of the 3 connected sources separately: from dynamic microphones to keyboards, from musical instruments (including guitars and basses with active pickups) to guitar pedalboards, from mixers to audio interfaces, including various devices (computers, smartphones, or tablets) with Bluetooth output.

Bluetooth audio connectivity & Speaker Linking

Today, it's essential to meet the needs of the public and clients, minimizing audio system setup times and cable clutter. Thanks to Bluetooth 5 audio connectivity, the Alto TS408 receives the signal played from laptops, mobile phones, and tablets. With the True Wireless Stereo function, you can configure the playback of your set of Alto Professional TS408 speakers to reproduce the stereo image of the original source. All without cables!

The integrated DSP in the Alto Pro TS408

There are three "Speaker Use" presets that you can select with the dedicated button on the rear panel: Live, DJ, and "Custom via App". The latter can be configured remotely using a 6-band parametric EQ available in the iOS/Android app. You can save your personalized equalization directly on the speaker to quickly recall it when needed. With the "Sub Size" button, you can choose the most appropriate high-pass filter for use with small, medium, or large subwoofers.

Alto TS408 adapts to your needs

Lightweight (just over 9KG) and compact (436x256x245mm) despite its power, this powered speaker can be positioned in any way: on a stand thanks to the standard 36mm hole in the base, on the floor or as a stage monitor thanks to the particular shape of the cabinet, or suspended thanks to the integrated M6 threaded suspension points. Passive cooling, meaning the absence of a fan, allows the TS408 to be used in environments that require particularly silent equipment: from theatrical performances to places of worship.
