Introduction
The RSC-112 screen channel loudspeaker and the RSB-212 subwoofer are the components of the QSC Reference Monitor System, a high performance,
studio-quality loudspeaker system for critical mixing, monitoring, and presentation. One RSC-112 3-way loudspeaker is paired with a matching
RSB-212 dual-driver subwoofer, along with factory-specifi ed signal processing and power amplifi cation for optimal performance when sound quality
is paramount.
The RSC-112 screen channel loudspeaker features a 12” (305 mm) woofer with 4” (102 mm) voice coil for exceptional low frequency bandwidth
reproduction. The LF driver crosses over into a high power capacity, neodymium mid-frequency compression driver with 3.5” (90 mm) voice coil and
coaxially-mounted 1.75” (44 mm) voice coil high-frequency driver.
The RSB-212 subwoofer features two specially-designed long-throw 12" (305 mm) woofers with 3" voice coils for exceptional extended bandwidth
sound reproduction. Each woofer is loaded in its own tuned chamber. Fully radiused ports ensure smooth air fl ow through the ports, especially at
higher drive levels. This prevents potentially audible port turbulence noise. Both internal and external port openings are fully radiused.
Both the RSC-112 and RSB-212 receive customized signal processing from a matched QSC Q-Sys™ processor core. The Q-Sys core provides Intrinsic
Correction™, a set of proprietary pre-set DSP tunings implemented in FIR fi lters that provide the most accurate acoustical magnitude, frequency, and
phase domain performance possible.
QSC DCA power amplifi ers deliver the correct level of amplifi cation into get the most out of each RSC-112 and RSB-212, producing the cleanest sound
with nearly undetectable levels of distortion.
For installations where there is no baffl e wall, the RSC-112 (along with the RSB-212 subwoofer) can be installed with optional baffl e wings (RBK-12)
which provide low frequency loading and minimize behind-screen refl ections.
The Reference Monitor System is specifi cally designed to be used with a Q-Sys Core 250i or 500i for the digital signal processing, a DCA 1222
amplifi er for the high and mid range frequencies, and a DCA 3022 amplifi er for the low and sub range frequencies. The installation process requires
that a Q-Sys design be created by a Q-Sys certified designer for the specific venue. Ensure that you employ a Q-Sys Certified designer to create the
Q-Sys design.
This User Guide tells you how to set up an RSB-212 subwoofer, with an RSC-112 loudspeaker stacked on top, and one baffl e kit for each of the two
loudspeaker enclosures. For detailed information about the amplifi ers and Q-Sys hardware, refer to the respective User Guides.
