Lesson Description
In this video, we dive into the intelligent, onboard QSC AWARE™ system that communicates essential setup information to the user via any loudspeakers's Rear User Interface (RUI) or QSC SysNav™ App
Lesson Transcript
0:08
The L Class line array system is equipped with an Automatic Wireless Array Recognition system
0:14
called QSC AWARE™.
0:16
a little on the nose…
0:19
The AWARE technology uses active internal accelerometers and infra-red communication links within each loudspeaker
0:25
to determine the status, position and angle of each loudspeaker in the array,
0:29
as well as the total number of boxes in the array, and the global tilt and coverage.
0:34
All of this data is then used to calculate what we call the Ar-Q Array Equalization
0:39
needed in order to achieve optimum performance.
0:42
From there the user can apply the recommended Ar-Q using the controls located on the loudspeaker’ Rear User Interface (RUI)
0:48
or via QSC System Navigator™ software app.
0:51
Let’s break that down:
0:52
After an array has been assembled and powered on, the array itself becomes self…aware.
0:58
Don’t worry, I’m not taking about a singularity. We’re still years away from a robot uprising. Probably…
1:04
Probably?…
1:06
The onboard sensors on each loudspeaker within the array
1:09
detects weather or not there is another loudspeaker both above and/or below it,
1:14
as well as the down tilt splay angle of that particular loudspeaker.
1:18
The information acquired by each loudspeaker is compiled
1:21
to calculate how many total loudspeakers are in the array.
1:24
With this information, it becomes possible to determine each loudspeaker’s position within the complete array.
1:30
And it does all of this within a matter of seconds. Because computers are fast. It’s pretty cool.
1:35
And not at all scary.
1:37
Without this system, the user would have to do all of this manually.
1:40
Which is tedious and not fun.
1:42
Once all of this information is determined,
1:45
the system will then calculate the necessary high frequency shading and band limiting
1:49
to be applied throughout the array to optimize it for the best performance possible.
1:54
This Ar-Q Array Equalization can be applied using the rear controls located on the Rear User Interface (RUI)
2:00
of any of the loudspeakers within the array with the touch of a single button…
2:04
What?
2:06
One button...
2:07
pressing a single button?....
2:08
yea.
2:09
Why...why does this need a training?
2:18
Scenario one, is that a single L Class loudspeaker is deployed.
2:22
This is pretty simple. When the loudspeaker powers on,
2:25
the QSC AWARE system will automatically determine the number of boxes,
2:29
in this case, 1, and the status of the loudspeaker.
2:33
If the loudspeaker is in factory default settings being either brand new or recently reset,
2:38
the status bar at the top will turn green with a single loudspeaker in the total array.
2:43
Both the gain and High Frequency shelf will be set to 0 dB and the sensitivity will be set to plus 24 dB.
2:51
If the loudspeaker is connected to the QSC System Navigator™ App, the network connection status will turn green as well.
2:57
Otherwise, the status bar will be greyed out
3:00
The high pass filter and EQ will both be greyed out, however the Ar-Q Array Equalization will be active,
3:06
which is displayed in blue.
3:08
A single L Class loudspeaker in factory settings will have Ar-Q Array Equalization.
3:14
If the loudspeaker is in a state other that the factory default, one of two display variations will appear.
3:20
If there is no change detected from the state in which it was last powered on,
3:23
the status bar at the top will display green and all of the settings will be displayed in the state at which they were set to previously
3:30
If there are changes to the settings from the last time it was powered on,
3:33
for example, if it was previously part of a multiple box array
3:36
and is now powered on as a single loudspeaker, the status bar will display orange.
3:42
All other settings will display in the state that they were previously set to.
3:45
And because the array is not in its last known state,
3:47
the message “Optimize Array – PRESS and HOLD KNOB” appears that the bottom of the screen.
3:52
To engage the auto Ar-Q Array Equalization, hold down the encoder wheel for three seconds as indicated.
3:59
With this done, the loudspeaker will be reset to the default settings for a single loudspeaker.
4:04
If the array compensation is engaged and you wish to undo the Ar-Q Array Equalization,
4:08
you can do so by pressing the back button within 3 seconds of the array compensation engaging.
4:18
The Second scenario would be more than one L Class loudspeakers connected together
4:23
and powering on in the same state in which they were previously setup.
4:26
the number of loudspeakers and their splay angles are automatically detected.
4:33
The status bar displays green and all settings are show in the state that they were previously set to,
4:38
including total number of boxes,
4:40
individual box angles, and all gain, high frequency HF shelving, EQ and high pass filter (HPF) settings.
4:47
In this scenario, no other action is required on your part
4:50
Simply connect your signal and go!
4:57
The third scenario is when an array is powered on in a random configuration with mismatched parameters from its last known state.
5:05
Let’s say you have the same inventory of speakers,
5:08
but they don’t always go back into the exact same location in each array every time.
5:13
In this scenario, the status bar will display orange.
5:16
The total number of loudspeakers will be displayed with the current loudspeaker highlighted in the array.
5:21
From here you can either press and hold the encoder wheel for 3 seconds to initiate the automatic array optimization process,
5:29
or enter your desired settings manually via the RUI if you want to voice the system manually.
5:35
Once the array optimization is complete, the status bar will display green and you’re good to go
5:41
After applying the recommended settings, we suggest giving a friendly thank you to the system for all its hard work.
5:46
That way when the robot overloads take us over,
5:48
at least they’ll know that you are a friend.
5:51
It’s also good to mention that the total number of loudspeakers recommended in an array is no more than 6.
5:57
If your array has more than 6 loudspeakers connected, you’ll receive the message
6:01
“Not a recommended array. Some features will be unavailable”.
6:04
If you get this message, you will need to disconnect some of the boxes so that the total is no more than 6,
6:09
or be prepared to operate the array as an unlinked system where all loudspeakers are managed individually.
6:16
That’s really it. The array did most of the work by itself.
6:19
All you have to do is press one button
6:22
and you’re ready to go.
6:23
Just…one.
6:25
Super simple.
6:27
If you are using the System Navigator app,
6:29
the information collected and calculated by AWARE system will be automatically delivered to SysNav.
6:35
From there a number of advanced functions will be available to you within the software.
6:40
We’ll get deeper into this within the System Navigator training.
6:44
QSC AWARE™ system leads to a consistent and repeatable experience in any venue or fixed installation
6:50
with a fast and efficient setup, every time.
6:53
That’s it for this video.
6:55
Your robot overlords thank you for your obedience and cooperation.
