With the Pioneer DJ DDJ-200 + Pioneer DJ HDJ-X7 Black + Pioneer DJ DM-40D Black, you can mix your favorite songs live in front of an audience. The headphones make it possible to pre-cue your mix, which means that you can prepare your mix with transitions and effects without the audience hearing that. You can hear detailed and clear sound from the headphones. The audience will hear the end result via the speakers. Thanks to the included apps and software, the controller is suitable for beginners. This way, you can quickly learn to mix with your favorite music. The laptop shows what you have to do and you can perform on the controller. You have to connect the controller, headphones, and speakers to the laptop and use the sound card from your laptop, because the controller doesn't have a sound card.
