The application for iOS and Android tablets and smartphones that allows you to control the DSP functions of your Alto Professional TS412 speaker: Bluetooth Volume, EQ presets, Custom EQ with 6 parametric bands and Stereo Link

Configure and control your Alto Professional TS412 amplified speaker from your smartphone and tablet thanks to the dedicated App available free of charge for iOS and Android devices. In the application you can configure the audio level via Bluetooth, the way to use the speaker, set your custom equalization (with 6-band parametric EQ) and the high-pass filter that best suits the size of your possible Subwoofer. In addition, you can configure the True Wireless Stereo Link directly in the app, thus minimizing setup times. A USB type A socket on the rear panel of the TS412 allows you to power/charge smartphones and tablets.
3-channel mixer integrated into the TS412

The rear panel with the 3-channel mixer integrated into the Alto Professional TS412 speaker. Two Mic/Line inputs on Combo connectors (XLR and ¼” TRS Jack), one wireless Bluetooth 5 with Pairing and Stereo Link functions. Mix Out XLR Link output

As in all models of the TS4 series by Alto Professional, the TS412 features an integrated 3-channel mixer: 2 mic/line on Combo connector (accepts XLR or 1/4” TRS Jack) and a wireless Bluetooth 5 with Pairing and Stereo Link function buttons. The Mic/Line selector on the combo inputs allows you to set the appropriate preamplification depending on the connected source. With the XLR “Mix Out” output, you can make cascade wired 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 pedals, from mixers to audio interfaces, including various devices (computers, smartphones or tablets) equipped with a Bluetooth output.
Bluetooth Audio Connectivity & Speaker Linking

Nowadays it is essential to be able to respond to the needs of the public and the client, minimize the time to put the audio system into operation and the clutter of cables. The Alto TS412, thanks to Bluetooth 5 audio connectivity, receives the signal reproduced by laptops, cell phones and tablets. With the True Wireless Stereo function you can configure the playback of your Alto Professional TS412 speaker set so that they reproduce the stereo image of the original source. All without cables!
The DSP integrated into the 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 custom equalization directly on the speaker to quickly recall it when you need it. With the “Sub Size” button you can choose the high-pass filter best suited for use with small, medium or large subwoofers.
