Why does a DJ use , Video 15, Filter on a CDJ?

0:00 These control what's known as the frequency

Alright folks, this is Jonathan here and this is number 15 in a selection of videos I'm doing entitled Why Does a DJ Use? In this one we're going to be looking at this here which is known as the filter button on a CDJ which is one of these guys. Now then, just very quickly, on a conventional DJ mixer you will have, on a modern day conventional DJ mixer, you'll have bass, mid and top. These control what's known as the frequency. Now what I'm going to do, I'm going to pan close to this particular button and what we'll do, we'll press play and we'll first of all listen to the music without using the filter. Now also on the DJ mixer, the bass, mid and treble are flat. In other words, they're not turned up or they're not turned down, they're basically either at 12 o'clock if you have a dial or if you have the small sliders, they're in exactly the middle position

1:32 How you can near enough make

Where they should be. Now what I'm going to do, I'm going to press the filter. Now then, what we can hear is a very high-pitched sound and as I move the filter you can hear it going to mid and that treble has been taken away and we only have mid and then we move it further down and now the treble and mid have gone and we're left with bass. Now what the filter's actually doing is it's taking away frequencies. We go up Get to mid, and we go higher, and we get to treble with a tiny bit of mid. Now then, what I want to do is I want to show you, because if you haven't got a filter effect, I can show you how you can near enough make a similar sound just by using your DJ mixer. I'm just going to pause the camera.

2:17 Decreasing the mid and increasing the bass, leaving the treble out as

Okay, like I said earlier, on a conventional DJ mix, a modern day one, you've got what's known as bass, mid and treble. They can be either like this, very small sliders or dials, like this. Now what I'm going to do, I'm going to turn the actual filter off on the CDJ, play that and I can show you near enough the exact sound you can get by using... The three band graphic here, or the low, mid, high, or bass, mid and treble. So what we'll do, as you can see the filter is off there, so we'll press play and away we go. Basically what I was doing, I was moving the treble higher and at the same time I was taking the mid away and the bass away. And then what I was doing, I was reducing the treble, increasing the mid, and then I was...

Decreasing the mid and increasing the bass, leaving the treble out as well. So that's near enough exactly the same sort of thing the filter will do but instead of using the filter on a CDJ if you haven't got a filter unit then you can just use the bass, mid and treble like so. I hope that's been a help but basically this video is describing how to use the filter and what it's used for. And also bearing in mind when you use the filter, 99% of the time you will use the jog wheel to give the effect. Thanks for watching, practice and enjoy!
