Hi my name is Chris
0:08:19
and today I'm going to walk through connecting your CP series loudspeaker to a subwoofer,
0:13:14
for applications in which you need a little extra low end extension.
0:17:03
We're going to cover a few scenarios that will help you select the best connection option for your setup.
0:21:16
In our first example,
0:22:18
we'll be connecting two CP Series top boxes
0:25:08
to a single subwoofer.
0:27:01
Just connect the main left and right outputs from your mixer to the A and B input of the subwoofer first.
0:33:09
Then use the parallel outputs located directly underneath each input
0:37:02
to connect to the left and right CP series top boxes.
0:40:06
This combines your signal in the subwoofer to mono,
0:42:23
but allows your top boxes to remain fully stereo in a Left/Right configuration.
0:47:08
It's important to connect your subwoofer first and then run that up to the CP tops
0:51:18
because the output on the CP Series is post gain.
0:58:13
separately from their back panels without one affecting the other.
1:02:03
In a two-sub application simply connect your left and right outputs to their respective side.
1:07:22
Plug into the subwoofer input A,
1:09:20
and use the parallel output to link to your CP top box.
1:13:12
Now each sub and CP connected
1:15:01
is running dedicated left and right stereo signal
1:17:23
in your setup.
1:19:06
Once you've got the loudspeakers wired up you can set your voice contour.
1:27:09
which activates the 80Hz crossover on that particular contour.
1:31:00
The Default contour is the standard, factory voicing of the loudspeaker
1:34:23
and can be used for use with live music, program music or instruments.
1:42:17
more suitable for program material like pop or electronic music.
1:46:12
With the “Ext. Sub” variation selected,
1:48:18
your system is optimized to work together with matched crossover.
1:52:04
In this setup, you can adjust your sub gain separately from the top boxes,
1:58:00
Our third example uses an auxiliary output
2:01:04
Simply take your left and right output from your mixer
2:03:16
to your left and right top boxes.
2:05:13
Then use an auxiliary output on your mixer
2:07:16
to connect to your subwoofer.
2:09:18
This gives you the ability to feed only the instruments that have low frequency into your sub
2:14:03
and have separate volume controls for the subwoofer and top boxes at the mixer.
2:18:04
You don't need to use two auxes if you have two subwoofers.
2:21:12
Just connect the first one normally
2:23:12
and connect the second sub to the parallel output of the first.
2:25:22
In this setup, you still want to engage the crossover
2:28:12
to optimize the system to work together.
2:30:19
This is a little bit more of an advanced setup
2:32:22
but it will give you separate control of both subs and tops individually.
2:36:14
Now that you've got the system wired up and your contour selected,
2:39:18
adjust your gain as needed and you're good to go!
2:42:03
Thanks for watching and we'll see you next time.
