Alto TS412 

12" 2-Way Powered Loudspeaker With Bluetooth, DSP and App Control

Overview

Building on the legacy of the popular TrueSonic speakers, the Alto TS 412 12" loudspeakers provide increased power, clearer sound and advanced Bluetooth functions including streaming, speaker linking and wireless control via the Alto App. Compact, lightweight and designed for reliability, the TS412 makes it simple to get great live sound at every event.

True Sonic Power

Whether you need a powerful vocal PA or club-shaking bass performance for a DJ set, TS412 speakers deliver loud, clear, room-filling sound for any application. With a 12" woofer and a 1.4" compression driver, TS412 delivers 2,500W of class-leading power and clarity in equal measure.

Alto App for Remote Configuration and Control

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

Built-in 3-Channel Mixer

Every TS412 features an integrated 3-channel mixer, with two mic/line input channels and a dedicated Bluetooth channel. 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 and Speaker Linking

The ideal high-powered streaming solution, TS412's built-in Bluetooth connectivity makes it easy to pair your laptop, phone or tablet and get the music pumping. With the True Wireless Stereo function you can stream Bluetooth audio to two TS412 speakers in perfect stereo, without the need for any cables.

DSP Modes for the Best Sound in Every Application

TS412's three preset "Speaker Use" modes let you optimize the speaker for any application, so you'll get great sound every time at the touch of a button. For even more control over your sound, you can configure a Custom EQ within the Alto App and remote adjust the settings from any listening point in the venue. You can even save your favorite Custom EQ setting direct to the TS412 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 TS412 has been designed for superb reliability, whether used for mobile gigs and performances or fixed installation. 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.

Key Features

Since their first iteration, the Alto Professional TrueSonic 12", two-way powered loudspeakers have excelled at delivering pro-level audio that's seriously affordable while not compromising on quality. The latest-generation TrueSonic 412, or TS412, doubles down on that promise, with smart new DSP, more power, flexible app control and stunningly effective Bluetooth wireless stereo linking.

Power in Reserve

Packing 2,500W of peak Class-D power, the Alto Professional TS412 has plenty of power to spare, providing the headroom you need for the best quality. Class-D amps also help make the TS412 incredibly lightweight, at just 33 lb. Alto Professional's fanless cooling designs help keep the weight down, as well, while adding to durability. The custom 12" low-frequency and 1" exit ceramic high-frequency driver combine with that massive power to provide a peak output of 132dB, so the TS412 is at home in any small- to medium-size venue.

Flexible, Customizable DSP

Expanding from previous analog designs into the world of Digital Signal Processing (DSP), Alto Professional has built immense flexibility into the TS412. With three available factory DSP presets—Flat, Live and DJ—plus a fourth, User Custom preset where you can store settings from the internal 6-band parametric EQ, the TS412 excels in almost any environment, whether pole-mounted, flown or used as a monitor wedge. The internal DSP also enabled Alto to have greatly increased control over internal filtering and limiting, which allows the TS412 to bring more clarity and punch to its output, delivering greater SPL while retaining equally great sound.

Easy App Control

Along with the DSP, the Alto Professional TS412 debuts a new mobile control app for iOS and Android devices. From the connected app, each TS412 is individually connectable and addressable, so each speaker in your system can have different settings, all controlled from a single location, offering unparalleled ability to tune speakers to a room. Or, individual band members can have control of the monitor in front of them from their own phone. The choices are plentiful. The app can change the speaker settings, control the EQ, control the Bluetooth volume, and more—virtually every user adjustable setting on the speaker is available from the app. 

Expanded Connectivity

When it comes to connections, Alto Professional provides all you expect, and then some. With two Mic/Line switchable, combination XLR/1/4" jack inputs and a Mix out, the TS412 can run as a standalone system for solo singer-songwriter gigs or speaking engagements, either singly, or in pairs. You can also switch the internal high-pass filter to match any size of connected subwoofer (from any manufacturer, not just theirs, as Alto pointed out to us), or set it to full-range when no sub is connected. The TS412's added Bluetooth capability goes beyond merely allowing you to play music from any Bluetooth device. A pair of TS412s can be stereo-linked via Bluetooth for a totally wireless stereo setup. There's even a convenient USB charge port to keep your smartphone or tablet topped off so the party can last all night. 

As has been their habit, Alto overdelivers with the TrueSonic 4 series. With massive power, immense flexibility and superb connectivity, these compact, lightweight powered loudspeakers make you and your band, or your venue, sound great while leaving some ducats in the bank for other gear.
