Quick Set-Up
In the following pages of this manual you will find a detailed explanation of system set-ups, but
if you just want to get started quickly you can follow the diagram and steps below to set up a
basic stereo PA system.
NOTE: It is important to remember the Golden Rule of audio … " LAST ON, FIRST OFF".
Translated, this means that when turning on your system, you should always turn your power
amplifiers or powered monitors on LAST, and when turning your system off, turn your power
amps off FIRST. This helps avoid any loud pops caused by inrush current at power up, which
can sometimes damage loudspeakers.
1 Before connecting your dB500’s, make sure that the power of all your systems compo-
nents is turned off. Also, make sure that your power amplifier volume controls and the
main left and right faders of your mixer are turned all the way down.
2 Connect the cables to your microphones and instruments, or a CD player, to your mixer.
3 Switch on the power of the mixer, instruments and/or CD player, and then switch on
your power amplifier.
4 While speaking into the mic (or playing the instrument or CD), raise the mixers main
Left and Right faders to the "0" position. Be sure that the mixer’s output meters are not
clipping. If they are, adjust the mixer volumes down until the signal cleans up.
5 Now, slowly raise your power amp until you reach the desired listening level.
