Alto Professional TS415 is a 2500W peak powered loudspeaker (RMS: 800W low, 450W high), covering a frequency range from 33Hz to 20kHz and equipped with three audio inputs with separate volume controls: two mic/line on Combo connectors and one wireless Bluetooth 5 with buttons for pairing and stereo link function. Max SPL: 135dB (peak), 132dB (continuous). DSP functions controllable via iOS and Android app.

Alto TS415: True Sonic Power

Whatever your amplification needs, the Alto Professional TS415 speaker offers an elegant and high-quality product, with a 2500W peak power, a 15” woofer and a 1” compression tweeter, respectively equipped with 2.5” (63mm) and 1.4” (35mm) voice coils and Class D amplified with 800W and 450W RMS. The frequency response ranges from 44Hz to 20kHz with a tolerance margin of +/-3 dB, extending down to 33Hz in the low frequencies with a tolerance of -10 dB.

Free Alto iOS and Android App  

Configure and control your Alto Professional TS415 powered speaker from your smartphone and tablet using the dedicated app, available for free for iOS and Android devices. In the app, 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 TS415 allows for charging/powering smartphones and tablets.

3-channel mixer integrated into the TS415

As with all models in the TS4 by Alto Professional series, the TS415 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 for setting the appropriate preamplification depending on the connected source. With the XLR “Mix Out” output, wired daisy-chain connections are possible. You can then 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) equipped with Bluetooth output.

Bluetooth Audio Connectivity & Speaker Linking

Today, it is essential to meet the needs of the audience and client, minimizing audio system setup time and cable clutter. The Alto TS415 , thanks to Bluetooth 5 audio connectivity, receives signals from laptops, cell phones, and tablets. With the True Wireless Stereo function, you can configure your set of Alto Professional TS415 speakers to reproduce the stereo image of the original source. All without cables!

The integrated DSP in Alto Pro TS415

There are three "Speaker Use" presets that can be selected 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 customized equalization directly to the speaker for quick recall when needed. The "Sub Size" button allows you to select the most appropriate high-pass filter for use with small, medium, or large subwoofers.

Alto TS415 adapts to your needs

Lightweight (17.2KG) and compact (643x417.5x402mm) considering the power and woofer size, this powered speaker can be positioned in any way: on a stand thanks to the standard 36mm hole on the base, on the floor or as a stage monitor thanks to the particular shape of the cabinet, or suspended thanks to the integrated M10 rigging points. Passive cooling, meaning the absence of a fan, allows the TS415 to be used in environments that require particularly quiet equipment: from theatrical performances to places of worship.
