0:00 Video response here going out to Brents

Alright folks, video response here going out to Brents. First question is where do I hook up the ground on the back of the mixer? Well what you'll find is on the back of every mixer you'll have a small little thing that sticks out that you can twist. It's either got earth or ground underneath it. What you do, you untwist it, you put your cables behind that, twist it back in so it's tight and there you go. These here, the phono, that's your power input but this is the back of the mixer. The next question, how do you organise your cables? I have a lot and I heard that they shouldn't cross each other. It doesn't matter. And duct tape has metal. No, duct tape does not have any metal. Duct tape is also known as gaffer tape. It has metal in it that will make it sound all wacky. Well, it won't. The only thing duct tape or gaffer tape will do is that if you put duct tape or gaffer tape over any cables...

0:51 Maximise acoustics, acoustics room

And you leave it on there for quite a while, it's a bugger to get off and it's really sticky and you get lots of residue all over your cables and it's not a good idea. So again if you think about it, if you keep the cables neatly placed it doesn't really matter. Let's say for example these two here are your cables left and right from your turntable and these are left and right from a CD player. It doesn't matter if they cross over, don't panic, it's not going to kill anything. Now then... What he's also said is, how would you maximise the acoustics in a room using just a... Hold on, what was it? Sorry. How would you maximise the acoustics in a room using just Tamaki speakers in a room, angles and everything? So I think what he's on about, he's got some Mackie speakers, how does he maximise the sound? Now generally what you'll find is a lot of DJs, there's the setup, mixer and decks. DX, they could be turntables, CD players, MP3. You have a speaker there.

1:48 Facing that way and a speaker there facing that way

Facing that way and a speaker there facing that way. If your room's quite small, try this. Put your speakers in each corner and have them at a 45 degree angle. So in other words, that is the way the speaker is facing. Like so, OK? Now what happens is the actual corners of your room act like a horn in a compression driver. What happens, the sound comes out and it hits that side of the wall. It's that side and bounces, and it actually amplifies it. The way to look at it is simply this. That's how it works like that. This is a horn, a compression driver. Let's say that's the magnet. That is where the diaphragm is, which is the part that vibrates causing the sound. And this is the horn. Works on the same principle. The sound comes out and hits either side, and as it hits either side, it bounces and it gets louder.

So that's what happens, so that's how you can actually maximise the sound. You won't feel a fanatical amount of difference but it will make your speakers sound a little bit louder. I hope I've been a help there to everyone else as well. Thank you for watching, practice and enjoy.
