Connect A Dj System

Connecting a DJ system requires only a basic understanding how audio works. As long as you understand which cords go with specific components, and can read the words "in" and "out," then setup should be simple. It's always a good idea to arrive at an event fairly early so that a sound check assures the system will run fine for the event. Keep the setup near a power source to avoid long extension cords.


Instructions


1. Plug everything into power strips that either plug into power outlets or extension cords to power outlets. Make sure all electronic components are turned off until you are ready to perform a sound check. Some electronic components come with attached power cords and others require separate cords. It's important to only use power cords that correspond with specific audio components. Use duct tape to tape down cords for safety and aesthetic reasons once you are sure where the system will be set up. Keep power strips turned off until you are ready for your sound check.


2. Connect the outputs of the audio sources to inputs on the mixer. A source is any device that plays audio or allows audio to be manipulated. It can be a microphone, CD player, turntable, tape deck, iPod, computer or any other audio device. The number of channels on a mixer determines the number of sources that can run through the mixer. Each channel has controls and effects. All channel sliders along with the master volume should be turned all the way down to prevent sudden, unwanted noise.


3. Connect the mixer's outputs to the amplifier's inputs. The mixer is the combination of sounds from various sources that is then amplified. Some systems, especially those with classic turntables, use pre-amps that feed into a bigger amplifier. Always have the amplifier volume turned all the way down until you are ready to test the system. Turn the amp on to make sure the power light is on. Some amps require fuses to be replaced every now and then, so it's a good idea to have a backup fuse.


4. Connect the amplifier outputs to the speaker inputs. The cables running from the amplifier to the speakers will likely be the longest cables in the system, so they require the most care and organization. Audio quality diminishes with cable length, so it's a good idea to assess the acoustics and achieve the best sound with economy of space and cable length. Tape down long cords. If the speakers are powered or have volume controls, make sure they are turned all the way down until sound check.


5. Perform a sound check. Test the system with a microphone or song. Make sure all components are turned on. Before turning up the master volume on the mixer, set volume levels on the amp and speakers. Next, turn up the master and the channel of the source you are testing. If everything is hooked up properly you should hear sound right away. If you do not hear sound you will need to troubleshoot the system. The first thing to check is power. Then check for cord corrections. Next, make sure the mixer switches are set up correctly. If there is still a problem, try different audio cables. If you still can't hear audio be prepared to set up a backup system.
