Kool sound Pearl 5 from Kool Sound

0:00 These particular cabs, I just want

Alright folks, quick demo on these guys here. They're from a company called Pro Audio Imports. They're known as the CoolSound Pearl 5. Now these guys are known also as powered speakers. Now first of all, before I talk about these particular cabs, I just want to explain powered and non-powered for a lot of people out there. Now if we look at your general DJ setup, you've got your music source, your vinyl turntables, your CD players, maybe your PC program. Then you've got a mixer. Now, from your mixer you need to of course make the sound louder. You've got a couple of options. One is you can go into an external amplifier. Now that's the guy that will make the sound louder. But of course an external amplifier, you then need speakers. So you go from music source to mixer. Out of mixer into external amplifier. Then out of external

Powered speakers. Now these guys here are powered speakers, so what does that mean? Well it basically means that the amplifier or amplifiers in this case are inside the speaker itself. So, what you'll do, you'll go from your music source into your mixer. Out of your mixer, directly into these guys and then you will get sound, so there's no need at all for an external amplifier. Right, what I'm going to do now... Pause the camera and we'll have a closer look at the back of the speaker and I'll give you a general idea of what's going on. Okay, first of all we've got a couple of dials here. We've got HF level adjust. HF is short for high frequency level adjust. And we've got volume control. Now this guy here will increase and decrease the intensity of the treble speaker, the small dome speaker at the top.

1:54 Your mixer

Now the volume control isn't set as in 1, 2, 3, 4 up to 10. It's set in dB. So again, ideally you need to set this in between the minus 6 and the plus 3 so you're near enough at 0 dB again. Now let's say you want to get pro audio sound out of your speakers. This is what you've got to do. Look at your mixer. Make sure your bass, mid and treble is at 12 o'clock. They're all in the flat position. Then, bung a tune on and have a look at your LEDs. You need to have your LEDs tapping at zero dB. And then if all this is at zero dB, the sound basically you will get from your speakers is near enough exactly the same sound that was made when that tune was made in the recording studio. Right, RCA, we've got a balanced jack and XLR.

3:17 What the heck is that?

Now again, loads of people say, you know, should I have an XLR cable going from your mixer into my speakers? Well, yes, if your speakers are going to be a long distance away from you. But, if your speakers are going to be relatively close to you, then there's no need, just a basic RCA will do. Alright, I'm going to pause the camera and we'll have a look at this info here and I'll give you just a bit of info on this info. Right, here we go. The reason, one of the main reasons I wanted to do this was this little word here, ferrofluid. So what the heck is that? Well, what you do find in a lot of good pro speakers, you will have ferrofluid surrounding the coil, the voice coil. Now if you imagine the speaker itself, you have two magnets and in between those two magnets you have the coil, the voice coil.

We'll have Ferrofluid around it. Basically, that fluid will help to cool down the coil, enabling it to work more efficiently. Right, 75 watts. Now these guys have got two amplifiers in them. One for the big speaker, one for the little speaker. And then frequency response. Basically, Van is telling me that these units will work from 53 hertz up to So if we just zoom out here, I want to show you this area. Now this is so important, please take this info in. We've got here 115V230V. Now V stands for volts. Now basically this here is set for your country. Now for crying out quiet, if you think... That by setting, let's say for example your country, the voltage in your country is 115 volts. If you think, oh if I switch that over to 230 it will be louder, then you're very very wrong because you will knacker your speakers, they'll possibly blow up, you'll knacker your warranty and you'll be crying your eyes out. So for goodness sake, leave that alone. Alright, a quick look at these guys here.

From a company called Pro Audio Imports, the cool sound, Pearl 5. Now what I'm going to do is bung a tune on and we'll have a listen. Now bearing in mind as well, what you're listening to of course is the sound from there into the camera, at the camera, onto my PC, off my PC, onto the web. Off the web into your speakers, so you're not going to get a true audio sound, but it'll give you a general idea. Let's turn it up a bit. What I'll do, I'll bungam the name of the track in the description as well, alright? Practice and enjoy!
