Unit 1: Live Sound (Part Two)

This is another example of Live Show in E127 (click on the link here E127 Picture). Unlike theatre room, this room does not have wall boxes instead we use the stage box for microphones (wired), drum kit, guitars and pianos (keyboards) to input straight to the mixer while the wireless microphones (colour coded) are connected by the monitor which is also connected to the mixer. The bass does not need to be connected because of lack of space. However you had to turn it up not too loud, otherwise this will cause the microphones to pick loud noises to disrupt the speakers (other known as the feedback).

The speakers (High, Mid and Sub) are placed like a ‘V’ position to the audience unlike straight to the audience in the theatre room. Each of the speakers is connected to each of their amplifiers along with the crossover to separate the frequencies to balance all of the sounds. The vocalists and the drummer are given the stage speakers to hear all the sounds of all the instruments including theirs.

There are health and safety that they are the same but different. Like for example:

1. Make sure the wires are wrapped up nicely to avoid the ‘spaghetti junction.’ To avoid it, here is a tip for placing the wires nicely:

Try placing the wires layer by layer so the wires would not overlap each over.

2. Get the wires duct tape together so they would not get separated.

And finally:

3. If a wire is dodgy like for instance: a Mid Rage speaker wire is not working, use the speak-on to speak-on with the plug that you can plug speak-on to jack and the solution will be solved.

Another health and safety is that be very careful of the stage box when it is placed on the floor. Try place the stage box in front of the drum kit so the stage box will be safe and also careful when walking over the big wire (other known as The Big Snake) as it can trigger the wires to break and cause the mixer to fall off and burst.

When the night falls, there are lights to look at the performers that maybe easy but sometimes for technicians/engineers find it hard to see in the dark. The best solution is use a torch to see the mixer properly and be careful where the wires are in case you have you have night vision clear, if not then use your torch.

To conclude, this is very different to the theatre room, but shows this is more hard work to rig everywhere so it is all about learning different areas that we all have to try something new.
