Ready for more? Let's get going.
00:11
Now to our Premium Performance range:
00:13
One of the things that distinguishes our Premium Performance range of screen channel loudspeakers is that they are 4-way systems that use our coaxial driver.
00:22
They all feature extended frequency response, with nearly zero distortion compared to conventional compression drivers.
00:29
Our Reference Monitor System is recommended for Small rooms like post-production facilities
00:35
and high-end home cinemas that require the very best premium performance.
00:39
This system includes the RSC 112 screen channel
00:43
and uses the same coax driver as the larger systems to bring this exceptional performance to small rooms up to 35 feet or about 10m long.
00:52
The RSC 112 Reference Screen Channel, paired with the RSB 212 Reference Subwoofer, are part of the Reference Monitor System, or RMS.
01:02
The RMS is processed by Q-SYS and powered by DCA Series amplifiers.
01:08
These high-performance loudspeakers are sold as part of a SYSTEM with matched QSC processing and amplification.
01:15
The Premium performance SC 414 is also aimed at slightly larger screening rooms
01:21
and post-production facilities and is also often chosen for large home cinemas where its moderate height can be helpful.
01:27
A deciding factor for choosing the SC 414 versus the Reference Monitor System is the 414’s large midrange horn which provides better directivity in larger rooms.
01:39
The SB 7118 and SB 7218 subwoofers are still great choices in this category for use with Premium 4-way screen channels like the SC 414, 424,434 and 444.
01:54
As you see in this diagram, for best results, the quantity of subs should be increased based on room length in premium rooms.
02:02
It is not uncommon to use eight of the SB 7218 subwoofers in a large PLF, or Premium Large Format auditorium.
02:11
For the absolute best possible subwoofer performance, QSC offers the SB 15121.
02:19
This sub uses a massive 21” woofer with a 6” voice coil, resulting in air volume displacement nearly equal to THREE typical 18 inch subwoofers.
02:29
For extended bass, minimal power compression and low distortion, there is no better option.
02:36
As with the SB 7218, there are many large PLF rooms that use multiple SB 15121’s and the results are amazing.
02:46
If a tight budget prevents you from using enough SB 15121’s, then we recommend using multiple SB 7218’s instead.
02:56
The surround loudspeaker options for Premium Performance are the same as they are for the “Best Value” class.
03:02
For 7.1 applications, the SR 8200 for smaller rooms, the SR 1020 for medium rooms and the SR 1030 for large rooms.
03:12
And for immersive systems, The 12” SR 1290, the 15” SR 1590 and the very large, high output SR 5152 15” 2-way design.
03:25
Aside from ROOM SIZE and Price/Performance expectations,
03:28
sometimes special installation requirements or “specialty applications” can also influence the optimal QSC loudspeaker selection.
03:37
For example - several models are designed for safe overhead suspension.
03:42
All of these models feature plywood construction instead of MDF and the larger loudspeakers have M10 mounting points for use with “rated” forged-steel eyebolts.
03:53
All of these models have been tested for superior structural integrity, but safety depends on the method of attachment and the building structure,
04:01
so we definitely recommend you consult a structural engineer if you are not experienced with loudspeaker mounting and rigging.
04:08
We have Screen Channels that are specifically designed to be suspended or Flown – denoted by the “F” in the model name – as well as surround subwoofers
04:18
like the SB 118F and 218F, all with M10 points for safe rigging.
04:24
The SR 1290 and 1590 feature threaded inserts to fit standard third-party multi-axis brackets or QSC yokes for easy aiming.
04:34
The largest surround. The SR 5152 has M10 mounting points and yoke options for maximum flexibility as well.
04:44
Remember, because of QSC’s Directivity Matched Transition and axi-symmetric design,
04:50
our SR Series surround speakers do not require special aiming adjustments – pan and tilt are all you need.
04:58
Once we’ve decided on the right loudspeakers for our application, it’s time to choose the right processor and amplification.
05:05
Usually, your processor choice will drive your amplifier selection.
05:09
We’ll build a chart to help make it clear, and we’ll start with the most complex systems first, then move on to simpler ones.
05:16
Is your application a Dolby Atmos system?
05:19
If so, a Q-SYS Core processor with CX-Q Series amplifiers are the best choice.
05:25
Q-SYS provides all the monitoring, signal routing, and crossovers required when using a Dolby CP 850 or IMS 3000 to render Atmos Immersive content,
05:36
and can also provide all the control needed for any cinema application.
05:41
Now we’ll move on to what we call “Advanced” 7.1 solutions, still using Q-SYS.
05:47
A Q-SYS Core processor along with the DCIO and CX-Q Series amplifiers will provide all of the I/O normally needed in a 7.1 cinema sound system.
05:58
And since Q-SYS is a networked solution, we can place amplifiers, I/O, and processing where it is most convenient, and control and monitor them from the network.
06:08
This is ideal for so-called “boothless” cinema designs.
06:12
And remember, Q-SYS is a lot more than just a Cinema processor.
06:16
It’s an entire processing Ecosystem that can also handle BGM, control of 3rd party devices, event conferencing,
06:24
and almost any AV requirement for the entire multiplex cinema or multi-use venue.
06:31
While Q-SYS for Cinema offers many advantages over traditional audio processors,
06:36
we realize some of you may not be ready to make that leap into software based, networked cinema systems.
06:42
For applications where you've decided not to use Q-SYS, but that require a processor with system monitoring, crossovers for 5.1 and 7.1,
06:51
and a booth monitor, our DPM Series processors with DCA Series amplifiers are the way to go.
06:59
The fourth option is for a system using a non-QSC cinema processor like a Dolby CP 750 or other brand, but you still want crossovers and a booth monitor.
07:10
Here we recommend our DCM 300 and again, our legendary DataPort-enabled DCA amplifiers.
07:18
On a side note, when it comes to processor choices for special applications, like immersive systems, post-production and high-end home cinema,
07:27
you may want to get our QSC Application Engineers involved early on in the design phase.
07:33
Alright, let's take a break there and come back when you're ready.
