Developed specifically for the unique

requirements of professional motion

picture playback, the SC-222 extends

QSC’s commitment to the cinema

market. As a member of the DCS Digital

Cinema Speaker Series, the SC-222 is

a bi-amplified, 2-way screen channel

loudspeaker system comprised of two

main units—the HF-75C high-frequency

system and the LF-2215 low-frequency

system.

The HF-75C high-frequency system

features a 3” (75mm) titanium diaphragm

compression driver mounted on a custom

designed high-frequency cinema horn

with an adjustable pan and tilt bracket.

The HF-75C 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 smooths the frequency response of

the horn/driver combination. The driver

and equalization network provides for

more reliable operation, ensuring the

show will go on. LF-2215 dual 15” (381

mm) low-frequency enclosure is designed

specifically to address the extended low-

frequency response required for cinema

applications.

LF-2215 covers the frequency range from

37 Hz to 1000 Hz, depending upon the

high-frequency system requirements.

Close Coupled Woofers (CCW), with their

tight spacing between woofers, improves

coupling and keeps coverage angles wide

over a greater frequency range than more

widely spaced designs.

The SC-222 is designed for ease of

installation. The HF-75C components

come pre-assembled to reduce field

assembly time. Three bolts are all that are

required to secure the HF-75C to the top

of the LF-2215 enclosure.

Features

• Two-way, bi-amplified screen

channel system

• HF-75C provides 90°

horizontal by +20° to -35°

vertical coverage

• LF-2215 is constructed of

MDF and features single

woofer chambers

• Low-distortion waveguide

provides highly articulate

dialogue

• Shallow depth (20”) facilitates

installation behind the screen
