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-specified signal processing and power amplification 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 flow 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 filters that provide the most accurate acoustical magnitude, frequency, and phase domain performance possible.

QSC DCA power amplifiers deliver the correct level of amplification 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 baffle wall, the RSC-112 (along with the RSB-212 subwoofer) can be installed with optional baffle wings (RBK-12) which provide low frequency loading and minimize behind-screen reflections.

The Reference Monitor System is specifically designed to be used with a Q-Sys Core 250i or 500i for the digital signal processing, a DCA 1222 amplifier for the high and mid range frequencies, and a DCA 3022 amplifier 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 baffle kit for each of the two loudspeaker enclosures. For detailed information about the amplifiers and Q-Sys hardware, refer to the respective User Guides.

1. Stack the Loudspeakers

WARNING!: Make sure the loudspeakers are secured in accordance with the applicable regulations.

Refer to – Figure 2.

Carefully place the RSC-112 box on top of the RSB-212 box so that the four rubber feet on the bottom of the RSC-112 are set securely into the four cups on top of the RSB-212. The NL8 connection panels of both units should be vertically aligned, and all four sides should be aligned flush with each other.

2. Install the Baffles

1. Remove a total of eight M10 hex plugs; two toward the front of the left and right sides of each of the two boxes. Use a 6 mm hex wrench. — Figure 2
2. Place a split washer then a flat washer on each of eight M10 hex bolts.
3. Align the holes, in the two lower baffles, with the holes on the front edge of the subwoofer. — Figure 3

4. Insert four bolts with washers through the holes in the baffles and into the holes in the subwoofer.

5. Torque the four M10 bolts to no more than 10 ft/lbs (13.5 N.m). Use a 17 mm wrench.

6. Repeat this procedure for the top loudspeaker box.

3. Connections

This section contains information about the connections between the DCA amplifiers and the RSC-112 and RSB-212 loudspeakers. For the remainder of the system connections, refer to the owner's manuals for the specific equipment. Refer to — Figure 4.

NOTE: Using standard, pre-made, NL8 connector/cables, ensures the wiring will be correct. This procedure assumes that all eight wires are connected in all NL8 connectors. — Figure 5 shows the male connector's pinout.

1. Plug the NL8 connector/cable, from the amplifiers, into the top NL8 receptacle on the RSC-112 enclosure. If you are using a fully wired NL8 cable, you may use any connector on either box.
2. Plug a short NL8 to NL8 jumper cable into one receptacle on each box.

Suspending the Reference Monitor System Loudspeakers

The typical installation of the Reference Monitor System is to stack the loudspeakers as detailed above. However in the event that you need to suspend the loudspeakers, the RSC-112 and RSB-212 each have 16 M10 suspension points: four on top, four on the bottom and four on each side that can be used to suspend the loudspeakers.

WARNING!: Read and follow these instructions carefully. If the loudspeakers are not suspended properly, they could fall, causing personal injury and damage to the equipment.

Rules for Suspension

• Consult a professional mechanical or structural engineer, licensed in the jurisdiction of the sound system installation, to review, verify, and approve all attachments to the building or structure.
• Employ the services of a certified, professional rigger for hoisting, positioning, and attaching the equipment to the supporting structure.
• Correct use of all suspension hardware and components is imperative in sound system suspension and deployment.
  • Always calculate suspended loads before lifting to make sure suspension components and hardware are used within their respective load limits.
• Consult local codes and regulations to fully understand the requirements for suspended loads in the venue in which you will suspend the equipment.
• Use only the M10 installation points for suspending the array.
• Be absolutely certain of the integrity of any structural member intended to support suspended loads. Hidden structural members can have hidden structural weakness.
• Never assume anything! Owner or third-party supplied suspension attachment points may not be adequate for suspending the loads.
• Before lifting, always inspect all components (enclosures, suspension brackets, pins, frames, bolts, nuts, slings, shackles, etc.) for cracks, wear, deformation, corrosion, missing, loose, or damaged parts that could reduce the strength of the assembly. Discard any worn, defective, or suspect parts and replace them with new appropriately load-rated parts.

Using Integrated Suspension Points

The Suspension points are located such that a single loudspeaker can be hung in a variety of orientations. The suspension points are designed for use with two M10-1.5, 30 mm long shoulder eyebolts.

1. Remove the appropriate plugs from the M10 installation points using a 6 mm hex key.
2. Thread an eyebolt into each of the appropriate M10 installation points.
3. Tighten the eyebolts until their shoulders are snug against the enclosure.
4. Continue to rotate the eyebolts until they reach the optimum desired in-line position. Do not overtighten.
5. The loudspeakers are ready for suspension.
