Subwoofer ativo Omnitronic AZX-115A, 400 W, altifalante de graves ativo

Omnitronic AZX-115A is a powered subwoofer with 400W of built-in amplification, designed to reproduce low-frequency sound for live PA systems, DJ setups and fixed installations. The active design integrates amplifier and speaker into a single cabinet to provide compact bass reinforcement, simplify system setup and deliver consistent low-end output. Use it to extend the frequency response of full-range loudspeakers, increase impact in music reproduction and provide controlled, reliable bass for playback and monitoring applications.

Advantages

The integrated amplifier and loudspeaker design eliminates the need for external power amplifiers, reducing cabling and setup time. A 400W power rating ensures sufficient headroom for transient bass content while maintaining stable output levels. The enclosure is tuned to reproduce deep low frequencies with controlled cone excursion, improving clarity and punch in bass-heavy material. Front-facing controls and connections allow straightforward integration into a variety of audio systems, and the active configuration provides optimized matching between amplifier and transducer for reliable performance.

How to use

Place the powered subwoofer on a stable surface or mount it according to the venue layout to achieve the desired bass coverage. Connect line-level outputs from a mixer, DJ controller or processor to the subwoofer inputs, then connect the subwoofer outputs to full-range speakers if required. Adjust the subwoofer level and low-pass crossover control to blend with the main loudspeakers, starting with conservative gain settings and increasing until the bass integrates smoothly with the system. Ensure mains power is connected and any protection or limit settings are enabled before full-volume playback.

Recommendations

For consistent results, position the subwoofer near the main speakers or at a location that minimizes room-mode buildup. Use the onboard level and crossover controls to avoid overlap or gaps between the subwoofer and satellites. During transport and storage, protect the cabinet and driver from impact and moisture. For installations, allow for adequate ventilation around the amplifier section and follow local electrical safety guidelines.
