SC-433 specifications
The QSC Audio SC-433 is a powerful two-way loudspeaker specifically designed for professional audio applications, offering exceptional sound quality and performance. It is an ideal choice for a variety of settings, including concert venues, theaters, and corporate events, where high-definition audio is paramount.One of the standout features of the SC-433 is its high-output capability. It incorporates a dual 12-inch low-frequency driver, providing robust bass response and the ability to generate high Sound Pressure Levels (SPL). Coupled with a 1.4-inch compression driver, the SC-433 reproduces clear and articulate high frequencies, ensuring that the full audio spectrum is delivered with precision.
The speaker employs advanced horn loading technology, which enhances the efficiency and directivity of the sound. This feature allows for better control of the coverage area, making it easier to achieve optimal acoustic performance in various environments. The waveguide design utilized in the SC-433 is meticulously engineered to provide a coherent and consistent sound field, resulting in less distortion and smoother frequency response.
Durability and rugged build quality are also key characteristics of the SC-433. The cabinet is constructed from high-quality plywood and finished with a durable coating, designed to withstand the rigors of touring and long-term installation use. Its design includes integrated rigging points and handles for ease of transportation and setup.
For added versatility, the SC-433 is equipped with QSC’s DMT (Directivity Matched Transition) technology. This innovation ensures a seamless transition between the low and high-frequency drivers, enhancing the overall sound quality and coherence of the audio output. Additionally, the speaker includes high-performance crossover components, ensuring that each driver operates within its optimal frequency range.
Another notable aspect of the SC-433 is its compatibility with the QSC Networked Audio System, which allows for seamless integration with other QSC products. This feature is particularly useful for larger setups, enabling sound engineers to manage multiple speakers and achieve a cohesive audio experience.
In summary, the QSC Audio SC-433 is a dedicated professional audio solution, characterized by its high output capacity, advanced sound technology, and robust construction. It is a versatile option suitable for various applications, providing reliable performance and exceptional sound fidelity in both live and installed sound environments.
