CP Series: Speech Contour

Hi everybody, it's Chris here from QSC.

In this video we're gonna have a look at the Speech Contour on the CP Loudspeaker Series.

Not only is the CP series great for music playback and live sound,

it also performs extremely well in speech applications.

If you're addressing a small crowd, leading a gathering,

holding a town hall meeting or simply making a quick announcement,

CP Series has got you covered.

All you need is a microphone,

cable,

and your CP loudspeaker.

If you were to take a typical loudspeaker without this setting and connect a microphone directly to it,

it would be immediately prone to feedback once you apply a moderate amount of gain,

so you'd have to stand far away and behind it

to keep you and your audience from being subjected to those annoying sounds.

To fix this,

people will typically add a small mixer and try to EQ problem frequencies out the mic input,

but that's extra equipment you'd have to connect and try to get set up quickly.

Here's how the Speech Contour eliminates all of those problems.

Let's start by plugging a microphone into our MIC/LINE input B.

For this demonstration,

we're going to use a standard dynamic handheld microphone.

If you want to use a headset mic,

that's fine too.

This setting is optimized to give great stability for both options.

A typical handheld mic also needs an input signal boost

to be able to reach appropriate levels,

so we have a MIC BOOST switch that applies a +25dB boost to your dynamic microphone.

If you're using a wireless mic plugged into your CP Series speaker,

you probably won't need to use that boost

because the receiver will be sending a line-level signal.

Select the “Speech” contour on the dial.

This activates digital signal processing, or DSP,

that gives clarity and stability to the microphone channel,

so you get a clean, stable sound,

with plenty of level without the risk of feedback.

After that, simply adjust your input gain to set your level and you're done!

It's important to note that when the speech contour is selected

only input B is affected.

Input A remains in the Default contour.

This is so you can have music playing on inputs A or C

without that being affected by the speech contour on the microphone channel.

So you get great sounding music playback and the ability to run a microphone,

without needing a mixer.

And, its compact size and light weight make this a portable and effective solution

that's easy to setup in no time at all.

Now, if you'll excuse me- I have an announcement to make.

Thanks for watching. We'll see you next time.
