USER MANUAL SC-312X QSC
Passive, two-way, screen channel system
SC-312X provides 90^ horizontal by +20^ to -30^ vertical coverage
- Low distortion waveguide provides highly articulate dialogue
- Shallow depth (20") facilitates installation
Developed specifically for the unique requirements of professional motion picture playback, the SC-312X extends QSC's commitment to the cinema market. As a member of the DCS Digital Cinema Speaker Series, the SC-312X is a passive, two-way, screen channel loudspeaker system comprised of two main units—the HF-63X1 high frequency system and the LF-3115 low-frequency system.
The HF-63X1 high-frequency system features a 2.5" (63mm) titanium diaphragm compression driver mounted on a custom designed high frequency cinema horn with an adjustable pan and tilt bracket. The HF-63X1 includes a driver protection and equalization network. DC blocking capacitors protect against DC or low-frequency signals that would likely destroy an unprotected driver. Power limiter circuitry protects the driver from overpowering and a response correction filter smoothes the frequency response of the horn/driver combination. The driver and equalization network provides for more reliable operation, ensuring the show will go on.
The LF-3115 15" (381mm) low-frequency enclosure is designed specifically to address the extended low-frequency response required for cinema applications. The LF-3115 covers the frequency range from 35 Hz to 1000 Hz, depending upon the high-frequency system requirements.
The SC-312X is designed for ease of installation. The HF-63X1 components come pre-assembled to reduce field assembly time. Three bolts are all that are required to secure the HF-63X1 to the top of the LF-3115 enclosure.

Cinema Loudspeaker Systems User Manual 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 loudspeaker.
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 associated with conventional horn loudspeakers. Equipped with a passive crossover 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 enclosures 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 cabinet. 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. Servicing 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, cabinets, 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, professional engineer when any doubt or questions arise regarding a physical equipment installation.

LF OUT Terminals
The HF-63X1 is designed specifically for use with QSC's LF-3115 low frequency loudspeaker and the HF-63X2 for the LF-3215 loudspeaker. The LF OUT terminals are factory-terminated to lead wires with spade-lugs. These should ONLY be connected to QSC's model LF-3115 or model LF-3215 low frequency loudspeaker. Observe proper polarity; connect the +LF OUT signal to the low frequency loudspeaker's + input, the -LF OUT signal to the low frequency loudspeaker's - input.

Cinema Loudspeaker Systems User Manual LF-3115 Low Frequency Loudspeake
Introduction
The LF-3115 15" (381mm) low frequency enclosure is designed specifically for cinema applications. Meeting cinema requirements for extended low frequency response differentiates the LF-3115 from more conventional "rock-and-roll" woofer systems. The LF-3115 covers the frequency range from 33 Hertz to 1900 Hertz, depending upon the high frequency system requirements.
The 300 watt, 15^ transducer is well suited for cinema use. It features a 3^ (76mm) voice coil, ceramic magnet, and a multi-vented pole piece to ensure cool operation. Cooler temperatures increase transducer lifespan and decrease the problem of power compression at high power levels. The suspension and voice coil of the transducer have been designed to provide low distortion and high impact bass at high power.
The enclosure is constructed of high quality medium density fiberboard panels with stiffening braces on all panels. Both internal and external port openings are fully radiused ensuring smooth air flow at higher power levels, preventing audible port turbulence. The stiffening braces reduce panel resonance.
Bass ports are evenly spaced on each side of the transducer, making internal pressure more uniform across the back surface of the transducer. This prevents the cone from being displaced to one side or another by unbalanced forces, reducing the chance of driving the voice coil out of the center of the gap at high power.
Three T-nuts in the top of the enclosure provide easy mounting of QSC high frequency systems, such as the HF-63.
Enclosure is not designed to be suspended, flown, or rigged. Do not suspend, fly, or rig this enclosure.
This product is capable of producing sound pressure levels that can permanently damage human hearing. Always keep sound pressure levels in the listening area below levels that can damage human hearing.
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. Servicing 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, cabinets, 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, professional engineer when any doubt or questions arise regarding a physical equipment installation.
