This is an ideal product to for students wanting to take their next steps into DJ-ing. Remember, that each DJ-505 will need to be linked to a classroom computer to play the various tracks you want to mix. Don't forget to add a microphone into the mix too. The Sontronics Solo would be a perfect choice for this.
