Developed specifically for the unique
requirements of professional motion
picture playback, the SC-423C extends
QSC’s commitment to the cinema market.
As a member of the DCS Digital Cinema
Speaker Series, the SC-423C is a 3-way,
selectable bi-or tri-amplified screen
channel loudspeaker system comprised of
two main units—the MH-1075C mid-high
frequency system and the LF-4215
low-frequency system.
The MH-1075C mid-high system features
a high output, horn loaded 10" midrange
cone driver and a 3" (75mm) titanium
diaphragm compression driver mounted
to an adjustable pan and tilt bracket. The
MH-1075C includes a driver protection
network and a passive crossover for
bi-amp operation. Power limiter circuitry
protects the high-frequency driver from
overpowering. The MH-1075C provides
extended frequency coverage for the
critical midrange band. A high power 10"
cone driver allows operation as low as
250 Hz and the advanced phase plug
coupling permits a crossover point of up
to 1800 Hz to the high-frequency horn.
This ensures that most of the dialog range
is reproduced by a single element, for
unmatched intelligibility.
The LF-4215 dual 15" (381 mm)
low-frequency enclosure is designed
specifically to address the extended
low-frequency response required for
cinema applications. The LF-4215 covers
the frequency range from 35 Hz to 250 Hz.
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-423C is designed for ease of
installation. The MH-1075C components
come pre-assembled to reduce field
assembly time. Three bolts are all that are
required to secure the MH-1075C to the
top of the LF-4215 enclosure.
