Large Room Solutions

The ultimate in big-room systems.

In a big room, it takes a big system to deliver big sound. QSC makes the only solutions that fully power the big-room experience while fully integrating system components. That’s particularly important in a large room because the sound system is often more complex.

  • Optimized high-power design delivers maximum power and intelligibility throughout large rooms without straining the system or endangering your investment.
  • Fast interfacing reduces the installation time spent on connecting large systems.
  • Networked audio routing minimizes signal losses, installation time, and cable costs from long audio runs.
  • Remote monitoring and control makes large-system operation more efficient.

Large Rooms and Premium Cinemas

Large Format and premium auditoriums are your marquee rooms. It takes a lot of low-end power to pump the excitement to every seat, and great mid/high coverage to make sure that dialog is clearly intelligible everywhere. QSC’s largeroom systems do it all, combining processing, amplification, and loudspeakers into a complete leading-edge solution. For Large Format and premium rooms, our 4-way screen channel loudspeakers are the ideal choice.

  • 4-way systems provide smooth reproduction of mid/high frequencies by incorporating a VHF driver that handles 6 kHz and above, allowing the HF driver to be optimized for the 1.7 to 6 kHz range that is critical for dialog intelligibility.
  • Unique ring radiator design time-aligns the acoustical centers of coaxial HF and VHF drivers, eliminating phase cancellation and uneven frequency response.
  • Switchable HF/VHF crossover lets 4-way systems run either quad-amped or tri-amped, depending on your amplifier and wiring budget. With 4-way configurations ranging from four woofers down to one, QSC’s screen channel options let you bring a premium movie listening experience to any size room.

Sample System Diagrams

Large Format/Dome

NOTE: This system diagram and the product list is only an example for a typical “large format or dome" room.
The exact product requirements for your specific room may be different.

System Components

  • DCP 300 is the most flexible and expandable cinema processor on the market, merging processing and booth monitor functions into a single-box solution.
  • DXP is the key to system expansion. Use it to route signal over CobraNet™ on Cat-5 cable from the DCP 300 to point-of-use DXP units, which connect via DataPort to DCA amplifiers. DXP also collects amp status information and feeds it back to the network for monitoring.
  • DCA amplifiers are the most reliable, best-performing cinema amps available. DataPort enables fast interfacing with both DXP and DCPs.
  • SC-424-8F is a flyable 4-way screen channel loudspeaker that can be suspended in either vertical or horizontal orientation.
  • SB-15121 uses a massive 21-inch driver to produce powerful, deep bass with superior definition and impact.
  • NAC-100 is a wall mounted network audio controller.

  • SC-444 is our largest screen channel loudspeaker. Four 15-inch woofers ensure clean, rich lows in even the largest cinemas, and a powerful midrange horn keeps critical dialog clear all the way to the last row.
  • SB-7218 dual 18-inch subwoofers achieve the lowest possible distortion while producing lows your audience can feel as well as hear. Ample port area lowers port-induced noise and power compression. (See also the SB-15121).
  • SR-1030 is one of our most powerful cinema surround speakers. A long-throw 10 woofer packs the punch of a much larger woofer with a coverage pattern that matches the horn. When even more SPL is required, our SR-1290, AP-5102, AP-5122, or AP-5152 offer more options for greater output.
