Ground Loop Isolator

Finally after installing the Virtual DJ program on my Apple macbook, I have found the sound quality to be much better then that of my HP Pavilion dv6-1103AX Laptop, which produced a very low noise and buzzing/crackling sound from my mixer/amp.

To get rid of this buzzing sound, I had to buy something called a ground loop isolator to eliminate this sound, I had purchased this for $25each from an electronic store, this device will need to go to each channel of your mixer (Channel 1 & Channel 2) connected through to your RCA cables and into your amplifier, this will eliminate that buzzing sound through the speakers.
