TS4 builds upon the legacy of our best-selling TrueSonic speakers, bringing powerful, clear sound and next-gen Bluetooth functionality including streaming, control (via the FREE Alto App), and True Stereo Wireless linking. Free Alto App for set-up 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. Simple Bluetooth Streaming and Linking TS4’s built-in Bluetooth connectivity makes it easy to stream directly from a device. And with the True Wireless Stereo function, you can stream to two TS4 speakers in stereo without the need for any cables. Integrated 3-channel mixer Every TS4 features an integrated 3-channel mixer, with two Mic/Line input channels and a dedicated Bluetooth channel. Sound great in every room TS4’s 3 preset DSP “Speaker Use” modes optimize the speaker for any application. For even more control over the sound, a Custom EQ can be set up within the Alto App and saved directly to the TS4 speaker. Ready for anything - compact, versatile design 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. Review: Ottime casse con rapporto qualità prezzo pazzesco - Prese 2 TS412 per sostituire 2 Mackie da 15” che erano molto più ingombranti ed avevano meno potenza. Ottime casse, suono pulito e le usiamo per i nostri piccoli concerti. In abbinata con 2 Subwoofer Alto TS12S copriamo tranquillamente spazi per 300-400 persone senza ammazzarci la schiena. Abbiamo anche 5 Alto TX310 e TX410 che usiamo come monitor/spie ed hanno potenza più che sufficiente per fare il loro lavoro. Consigliatissime sotto tutti i punti di vista +++ Review: Great crowd pleaser in the right environment - this speaker is a jack of all trades - it's got bluetooth, multiple connectors that support both TRS and XLR, and more. The build quality is pretty solid as well, no rattling, etc. Sound quality is great for a PA speaker, high and mid-end are super crisp. Low-end could be better, but that's the limitation of a 12" driver. Make sure that it's right for you though, as with everything audio-related, the room in which you're using the speaker matters just as much as the speaker itself. In a living room sized environment, the alto performs great, the sound quality, projection, acoustics, etc. are all excellent. Anything bigger, and you'll probably need to get an additional subwoofer, as its fairly lacking in lower frequencies. ## Features - TrueSonic Power - 2500W active PA speaker with 12-inch Low-Frequency driver and a 1.4-inch High-Frequency driver for superb performance - Alto App - Compatible with iOS and Android for remote configuration and control over Bluetooth levels, Speaker Use modes, Sub Size selection, and Custom EQ to remove unwanted feedback - Powerful Bluetooth Features - Including streaming directly from your laptop, phone, or tablet and True Stereo Wireless speaker linking.
