Hello and welcome back!
0:09
Today we’re taking a look at deploying an L Class line array using the array frame in a flown configuration.
0:14
That’s right, WE, us. Together.
0:18
There are two models of the Array Frame accessory. Each specific the LA108 and LA122 respectively.
0:24
It’s important to note that the array frame models
0:26
cannot be mixed and matched between the two Array loudspeaker models.
0:30
Let’s take a look at how to get it connected.
0:37
We need to get the angle bars on this loudspeaker into the 1.5 degree setting.
0:41
To do this, we’ll press the angle levers on both sides until they click.
0:46
Now push the angle lift bar up on both sides until it clicks into the next position.
0:51
This is now in the 6 degree setting.
0:53
We’ll push the angle levers once more on both sides and lift the angle lift bars
0:57
to get it into the 1.5 degree setting.
0:59
Now we’re ready to attach the first loudspeaker to the array frame.
1:07
With the frame properly secured to the rigging fixture or truss,
1:10
simply attach the first loudspeaker by hanging the front strikes of the loudspeaker onto the front hooks of the array frame,
1:16
then lift the rear handles of the loudspeakers until the Angle Bar reaches the array frame.
1:21
Secure the loudspeaker to the array frame using the Array frame rigging pins on both sides.
1:27
Make sure you secure BOTH pins in order to ensure a safe connection.
1:35
Now to complete your array, continue to attach the remaining loudspeakers
1:39
and set your splay angles using QSC RapidDeploy rigging system.
1:58
When setting your splay angles it’s important to be aware of the Progressive Splay angle rule.
2:03
This rule states that a larger splay angle value cannot be used above a smaller splay angle value,
2:08
as this will result in an unsupported array that is impossible to optimize.
2:13
The angle values must either match or progressively increase in size from the top of the array to the bottom.
2:18
For example we have a four box array here
2:21
with the angles 1.5, 6, and then 12 degrees from top to bottom.
2:26
An example of an unsupported array would be if you had the angels set to,
2:30
let’s say 12 degrees, 6 degrees and then 1.5 degrees from top to bottom. No good.
2:36
Technically, the hardware will allow for any combination of angles to be set throughout the arr
2:41
If the progressive splay angle rule is broken however, the internal optimization will not work.
2:46
Our engineers have spent a lot of time making sure that your array works with correct deployment angles,
2:50
so just follow the rule and save yourself lots of time and headaches.
2:55
In a flown configuration up to 6 L Class line array loudspeakers can be connected together and optimized.
3:04
When it’s time for tear down we can disassemble the array just as easily as it was put together.
3:09
Detach and remove the loudspeakers starting with the bottom unit
3:12
and work up to the top loudspeaker that is connected to the array frame
3:21
Now to detach the last loudspeaker from the frame,
3:24
hold one of the rear handles with one hand to support the weight
3:27
while removing the Array frame rigging pins on either side
3:30
to release the rear of the loudspeaker from the frame.
3:33
Notice that once detached from the rear,
3:34
the full weight of the loudspeaker is still supported by the two front strikes,
3:38
ensuring that the loudspeaker won’t fall.
3:41
Lift the loudspeaker off the front strikes to fully remove it from the frame.
3:44
and you’re done.
3:46
When rigging the array to your structure or trussing,
3:48
there are a series of pick points that will be used to attach the frame and set the desired tilt angle.
3:53
For a single pick-point deployment,
3:55
a 16 mm (5/8 inch) shackle can be attached to the center rail of the array frame at the center-of-gravity point for the desired angle.
4:03
The shackle is not included with the array frame.
4:06
Moving the pick-points forward or backward will adjust the overall tilt angle of the array.
4:11
SysNav or EASE software can help you determine the correct pick point location for your deployment.
4:16
You can also use two pick-points, or Bridle deployment, if you desire.
4:20
Simply attach two shackles, still not included, to the two outer rails of the array frame on parallel holes.
4:27
You also have the option of using an M10 Eyebolt, secured to the lowest loudspeaker in the array,
4:32
to provide another pick-point when a down tilt outside of the center of gravity of the array frame is needed.
4:39
When flying an array please keep all safety precautions in mind
4:43
Do not exceed the weight rating of any hardware or equipment
4:47
and when necessary always hire a professional mechanical or structural engineer,
4:51
to review and verify all attachment points to buildings and structures as well as certified rigging professionals for
4:57
hoisting, positioning and attaching any equipment to the supporting structure.
5:02
Safety comes first.
5:05
And with that, a single operator can successfully deploy a 6 box hanging array all by themselves.
5:12
That's all for this video. Thanks for watching and continue on to the next lesson whenever you're ready.
