HF-63X1 and HF-63X2

High Frequency Component

Introduction

The HF-63X1 and HF-63X2 are the high frequency components of full-range, two-way screen channel loudspeaker systems for high performance cinema applications. The HF-63X1 is designed specifically for use with QSC’s LF- 3115 low frequency loudspeaker and the HF-63X2 for the LF-3215 loud- speaker.

The HF-63X1/X2 high-frequency system features a large format, 2.5” (63.5mm) titanium diaphragm compression driver mounted on a custom designed high-frequency cinema horn with an adjustable pan and tilt bracket. The horn features broad horizontal and vertical coverage angles to ensure coverage of every seat in the auditorium. The horn is a low-distortion waveguide providing highly articulate dialogue without coloration associ- ated with conventional horn loudspeakers. Equipped with a passive cross- over providing tailored output for the LF-3115 or LF-3215, no additional signal processing is required.

The HF-63X1/X2 components come pre-assembled to reduce field assembly time. Three bolts are all that are required to secure the HF-63X1/X2 to the top of a QSC low frequency loudspeaker. Threaded inserts in the LF enclo- sures and matching punched hole pattern in the HF-63X1/X2 make mounting to the low frequency enclosure simple.

Mounting

Refer to the illustration for mounting information. The HF-63X1/X2 attaches to the top of the LF-3115 or LF-3215 with three 5/16-18 bolts, 0.75” long, with lock washers. This hardware ships installed on the low frequency cabi- net. We recommend the use of serviceable thread locking compound when installing the bolts to prevent loosening due to vibration. Aim the horn in the horizontal plane (pan) before tightening. Adjust the vertical tilt with the bracket adjustment.

Install in accordance with QSC Audio Product’s instructions and a licensed, professional engineer. Only use attachments, mounts, accessories, or brackets specified by QSC Audio Products, Inc. Refer all servicing to qualified personnel. Ser- vicing is required when the apparatus has been damaged in any way.

WARNING! Before placing, installing, rigging, or suspending any speaker product, inspect all hardware, suspension, cab- inets, transducers, brackets and associated equipment for damage. Any missing, corroded, deformed or non-load rated component could significantly reduce the strength of the installation, placement, or array. Any such condition severely reduces the safety of the installation and should be immediately corrected. Use only hardware which is rated for the loading conditions of the installation and any possible short-term unexpected overloading. Never exceed the rating of the hardware or equipment. Consult a licensed, profes- sional engineer when any doubt or questions arise regarding a physical equipment installation.

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.
