ALTO PROFESSIONAL TS312 12" Bi-Amplified Loudspeaker
Estimated delivery in Italy between 18 and 22 June
12” Bi-amplified Speaker
The ALTO PROFESSIONAL TS312 is a Class D bi-amplified speaker with passive cooling, a 12” woofer, frequency coverage from 46Hz to 22kHz, and a maximum SPL of 131dB peak. The new TS3 series of active speakers from Alto Professional, thanks to 2000W peak bi-amplification (1000W continuous), divided into 1300W for lows and 700W for highs, and new transducers, represents a professional and elegant solution suitable for various installations: on a stand, on stage, or suspended. The careful design has resulted in an aesthetically appealing, robust yet lightweight, and easy-to-transport speaker. On the back of each speaker, a 2-channel mixer is integrated, with combo inputs that accept line or microphone sources via ¼” jack or XLR connectors, and volume control; an output on a male XLR connector allows for daisy-chaining (LINK) between multiple speakers. The absence of cooling fans, replaced by a specially designed passive system, makes it an optimal choice for use in situations requiring minimal noise during pauses or with significant dynamic range, such as theaters, conference rooms, or acoustic performance amplification.
