CP Series: Subwoofer 2m 49s
00:07
Hi my name is Chris
00:08
and today I'm going to walk through connecting your CP series loudspeaker to a subwoofer,
00:13
for applications in which you need a little extra low end extension.
00:17
We're going to cover a few scenarios that will help you select the best connection option for your setup.
00:21
In our first example,
00:22
we'll be connecting two CP Series top boxes
00:25
to a single subwoofer.
00:27
Just connect the main left and right outputs from your mixer to the A and B input of the subwoofer first.
00:33
Then use the parallel outputs located directly underneath each input
00:37
to connect to the left and right CP series top boxes.
00:40
This combines your signal in the subwoofer to mono,
00:42
but allows your top boxes to remain fully stereo in a Left/Right configuration.
00:47
It's important to connect your subwoofer first and then run that up to the CP tops
00:51
because the output on the CP Series is post gain.
00:54
Using this method, you can control the levels of your subs and top boxes
00:58
separately from their back panels without one affecting the other.
01:02
In a two-sub application simply connect your left and right outputs to their respective side.
01:07
Plug into the subwoofer input A,
01:09
and use the parallel output to link to your CP top box.
01:13
Now each sub and CP connected
01:15
is running dedicated left and right stereo signal
01:18
in your setup.
01:19
Once you've got the loudspeakers wired up you can set your voice contour.
01:23
Both the Default and Dance voicings have an accompanying “Ext. Sub” variation,
01:27
which activates the 80Hz crossover on that particular contour.
01:31
The Default contour is the standard, factory voicing of the loudspeaker
01:35
and can be used for use with live music, program music or instruments.
01:38
The Dance contour has some low frequency enhancement and mid/high clarity
01:42
more suitable for program material like pop or electronic music.
01:46
With the “Ext. Sub” variation selected,
01:48
your system is optimized to work together with matched crossover.
01:52
In this setup, you can adjust your sub gain separately from the top boxes,
01:55
with the same signal coming from the mixer.
01:58
Our third example uses an auxiliary output
02:01
Simply take your left and right output from your mixer
02:03
to your left and right top boxes.
02:05
Then use an auxiliary output on your mixer
02:07
to connect to your subwoofer.
02:09
This gives you the ability to feed only the instruments that have low frequency into your sub
02:14
and have separate volume controls for the subwoofer and top boxes at the mixer.
02:18
You don't need to use two auxes if you have two subwoofers.
02:21
Just connect the first one normally
02:23
and connect the second sub to the parallel output of the first.
02:25
In this setup, you still want to engage the crossover
02:28
to optimize the system to work together.
02:30
This is a little bit more of an advanced setup
02:32
but it will give you separate control of both subs and tops individually.
02:36
Now that you've got the system wired up and your contour selected,
02:39
adjust your gain as needed and you're good to go!
02:42
Thanks for watching and we'll see you next time.
