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.
