SC-312X specifications

The QSC Audio SC-312X is an advanced two-way loudspeaker designed to meet the demands of various audio applications, from live sound reinforcement to installations in sports venues, auditoriums, and houses of worship. This versatile loudspeaker is known for its exceptional sound quality, durability, and user-friendly features that make it a popular choice among audio professionals.

One of the standout features of the SC-312X is its powerful coaxial design. Utilizing a 12-inch low-frequency driver and a 1.4-inch exit high-frequency driver integrated into a single point source, this configuration allows for a more uniform dispersion of sound across a wide listening area. This results in improved clarity and reduced phase cancellations, ensuring that the audio is consistent regardless of the listener's position in relation to the speaker.

The SC-312X incorporates QSC's advanced DMT (Directivity Matched Transition) technology, which is designed to provide a smooth frequency response across the entire coverage pattern. This technology enables the loudspeaker to maintain a consistent tonal balance both on and off-axis, making it ideal for applications where audience coverage is critical.

In terms of construction, the SC-312X is built to withstand the rigors of professional use. Its cabinet is made from rugged plywood, finished with a durable coating that helps protect against wear and tear. Additionally, the front grille is made from perforated steel, providing extra protection for the drivers while allowing for optimal sound output.

Another important characteristic of the SC-312X is its versatility in rigging and mounting options. The loudspeaker comes equipped with integral fly points, which simplifies the process of suspension in various configurations. It also features a stand-mountable design, making it suitable for both permanent installations and portable setups.

The speaker’s power handling capability is impressive, accommodating a wide range of amplifiers and making it suitable for large venue applications. The SC-312X delivers a powerful output without sacrificing audio fidelity, ensuring that every nuance of the performance is captured and conveyed to the audience.

In summary, the QSC Audio SC-312X is an exceptional loudspeaker that combines innovative technology with robust construction to deliver unparalleled performance in any professional audio setting. Its coaxial design, advanced DMT technology, rugged build quality, and flexible mounting options make it a reliable choice for audio engineers and sound professionals looking to achieve the highest standards in sound reproduction.
