| is there any specific way you should power up and down each equipment (mixer,amp/stereo, TTs/cdjs) ? what ive been doing is powering on my cdjs/TTs, then my mixer and then my stereo. |

mixer on first, then t-tables, then amp, reverse order to shut off, amp first, t-tables, mixer. |

Sources first, then any processor (the mixer can be accounted as a processor too, but count it as the last one in the chain), then the output.
The logic is that if the sources don't have the appropriate protection (most have now via condensators but let's keep it safe), when you switch them on (and off), they'll give some sort of peak. If your mixer and amp/speakers would already be on, this would give a pop that could damage your speakers (the pop is very loud). By turning the sources on first, they'll still give that peak, but there's nothing to pass that peak on to the output yet.
Same for the processors/mixer, it can give a peak signal when switched on that can damage the output devices.
Same goes for switching the devices off. They'll give a pop. So by shutting off the amps first, you'll ensure that you can't damage the speakers.
BTW, when dealing with big power amps, wait some time after switching the amps off. There's still some residual power in it the first moments after you switch it off (you might have noticed that after you turned the amp off, you can still hear some signal for a couple of seconds). The power is still strong enough to make the pop burst your speakers. |

| Oops... I never knew that the 'pop' was that bad for your system... Thanks guys. |

Also, before you turn anything on or off, make sure the volume channels on your mixer and amp are all the way down. This ensures that the peaks and pops that will go through your system are very much diminished by the resistors that control the volume levels.
This is especially important in clubs when you bring your own equipment. If you plug anything into a live mixer, make sure that it is not plugged in yet and make sure the volume channel is all the way down. Then plug in the RCA connections, then plug in the piece of equipment, then power it up, then you can adjust the channel volume. |

Just remember this and you should be fine:
"AMP: On last, off first." |
