Alto Professional TX312 — Professional Active Speaker for Demanding Audio Applications

The Alto Professional TX312 active speaker represents the highest quality in the portable sound reinforcement segment. This two-way speaker with a built-in Class D amplifier delivers a powerful 700 watts of peak power, sufficient for professional concerts, corporate events, or fixed installations in restaurants and music clubs. The device was designed and tuned in the United States, ensuring the highest standards of sound quality.

Product Features

The TX312 is equipped with a 12-inch woofer featuring a 2-inch voice coil, providing deep and powerful bass. The upper frequency range is handled by a 1-inch titanium diaphragm compression driver, which guarantees clean and detailed high frequencies. The precision horn with a dispersion pattern of 90° horizontally and 60° vertically enables optimal sound coverage for the audience, minimizing energy loss outside the listening area.

The built-in Class D amplifier delivers 350 watts of continuous power and 700 watts of peak power, providing the dynamics necessary for loud and energetic performances. The sound reproduction system operates in the 70 Hz – 20 kHz frequency range, covering the full spectrum of frequencies audible to the human ear. The crossover set at 2.5 kHz optimally splits the signal between the woofer and the tweeter.

Versatility of Applications and Configurations

The trapezoidal enclosure of the TX312 allows for two setup configurations: vertical as a main system speaker or angled as a stage monitor. This flexibility makes the speaker equally suitable for front-of-house sound reinforcement at concerts and as stage monitoring for musicians. The standard 36 mm socket allows mounting on any speaker stand, and the full-size metal grille protects the transducers from mechanical damage.

The Contour switch allows boosting low and high frequencies by 3 dB, enabling the sound character to be adjusted to the room acoustics or listening preferences. The Ground-Lift function effectively eliminates unwanted hum and mains noise that may occur when connecting to other audio devices. The built-in analog limiter protects the transducers from clipping and damage resulting from excessively high input signal levels.

Materials and Construction

The TX312 enclosure is made of injection-molded polypropylene, which combines lightness with mechanical durability. This material effectively dampens unwanted cabinet resonances, contributing to a cleaner sound. The full-size metal mesh grille protects the transducers from accidental impacts and dust, which is particularly important during intensive concert use. Rubber feet absorb vibrations and prevent the speaker from sliding on smooth surfaces.
