Alto Professional TS412 is a powered loudspeaker with a 2500W peak output (RMS: 800W low, 450W high), covering a frequency range from 44Hz to 20kHz. It features three audio inputs with separate volume controls: two mic/line combo inputs and one wireless Bluetooth 5 input with pairing buttons and stereo link function. Max SPL: 132dB (peak), 129dB (continuous). DSP functions controllable via iOS and Android app.

Alto TS412: True Sonic Power

Whatever your amplification needs, the Alto Professional TS412 speaker offers an elegant and high-quality product, with 2500W peak power, a 12” woofer and a 1” compression tweeter, respectively equipped with 2.5” (63mm) and 1.4” (35mm) voice coils, and Class D amplification with 800W and 450W RMS. The frequency response ranges from 53Hz to 20kHz with a tolerance margin of +/-3 dB, extending down to 44Hz in the low frequencies with a tolerance of -10 dB.

Free Alto iOS and Android App  

Set up and control your Alto Professional TS412 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 usage mode, set your personalized equalization (with a 6-band parametric EQ), and the high-pass filter that best suits the size of your potential subwoofer. Additionally, you can configure the True Wireless Stereo Link directly in the app, minimizing setup time. A Type-A USB port on the rear panel of the TS412 allows for powering/charging smartphones and tablets.

3-channel mixer integrated into the TS412

As in all models of the TS4 by Alto Professional series, the TS412 features an integrated 3-channel mixer: 2 mic/line inputs on combo connectors (accepts XLR or 1/4" TRS Jack) and one wireless Bluetooth 5 input with buttons for Pairing and Stereo Link function. The Mic/Line selector on the combo inputs allows you to set the appropriate pre-amplification depending on the connected source. The "Mix Out" XLR output enables wired daisy-chain connections. You can therefore connect directly to your speaker and separately control the volume of the 3 connected sources: from dynamic microphones to keyboards, from musical instruments (including guitar and bass 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

Nowadays, it is essential to meet the needs of the audience and the client, minimizing audio system setup time and cable clutter. The Alto TS412, thanks to Bluetooth 5 audio connectivity, receives signals from laptops, mobile phones, and tablets. With the True Wireless Stereo function, you can configure your set of Alto Professional TS412 speakers to reproduce the stereo image of the original source. All without cables!

The integrated DSP in Alto Pro TS412

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 in the iOS/Android app. You can save your personalized equalization directly on the speaker for quick recall 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 TS412 adapts to your needs

Lightweight (15KG) and compact (606.5x353.5x350.5mm) considering its power, this powered speaker can be positioned in various ways: on a stand thanks to the standard 36mm pole mount socket at the base, on the floor, or as a stage monitor due to the cabinet's special shape, or suspended thanks to integrated M10 rigging points. The passive cooling, meaning the absence of a fan, allows the TS412 to be used in environments that require particularly quiet equipment: from theatrical performances to places of worship.
