If you have wired up a system and are experiencing problems, here are a few troubleshooting tips to hopefully resolve your problems.

LOUD NOISE DAMAGES EARS, INCLUDING YOUR OWN, BE CAREFUL! 

1. Make sure that all of the pieces of equipment you are using are:- 
a). Turned ON, and b). Are Turned UP.

2. Be methodical about solving the problem, 99% of problems are caused by user error. Don't panic there's usually a way around a problem, even a serious one.

3. One of the most common mistakes people make when hiring equipment off of us, is thinking that there are leads missing, when in fact there is a compartment situated in the lid of the microphone case which houses them.  

4. Carefully check for any hiss coming out of the speakers. If there is, it means that the amplifier is delivering power to the speakers, and the problem is either with the settings on the mixer, (i.e. you need to turn up the volume on the relevant channel), or maybe the sound source, i.e. microphone/keyboard/guitar etc. isn't turned up.

5. A mixer amplifier usually has two or more volume controls. Master Volume: This is the overall volume control, which must be turned up for any volume to be available. Channel Volumes: These are the individual volume controls for each of the separate channels, and again whichever channel you wish to hear must be turned up. If, (in the case of microphones) there doesn't appear to be enough volume, there will usually be an extra gain control at the top of the channel, increase this until the volume is correct, (avoiding overload or clipping indicators)

6. If you do have a problem, the most likely area will be the leads. The simplest way of proving this will be to follow the path of the leads from the amp to the speakers, and change the leads one at a time, until you've find the faulty lead, replace this lead with a working one.

7. Loud Hum/Buzzing noise: This will usually be caused by a number of problems: Speaker leads (usually marked) can only be used to go from the speaker outputs to the speaker inputs If you have accidentally used a speaker lead instead of a Signal lead It will generate a very loud hum/buzz. Remedy: Change the lead for a signal lead, (usually a much thinner and flimsier lead than a speaker lead)

8. Signal leads: Must never be used as speaker leads as there is a danger of fire. Signal leads are much thinner and not capable of delivering the necessary power from an amp.
