    • Card: Internal Soundcard
    • Master: Set to your soundcard - Chan 1&2
    • Headphones: Set to your soundcard - Chan 3&4


Two Soundcards: 

While some laptops have internal surround sound cards and/or speakers, most only have a single headphone output.  The simplest option is to add a basic stereo USB soundcard or audio interface for your headphones, such as the Numark DJ I/O.

  1. If you are using an external USB soundcard, assign the Audio Settings as follows:
    • Output: Speaker + Headphone
    • Card: Two Soundcards
    • Outputs: Headphones (Master : First card / Headphones : Second card)
  2. In the Outputs section, choose the following:
    • In the first drop-down list, choose your laptop's built-in sound card.
    • In the second drop-down, choose your external USB sound card.
  3. Click Apply to complete.

Mono with a Y splitter cable:

You can use a single sound card and the mono separated option in VirtualDJ's sound setup, however, this will only give you MONO sound.  You will need a Y-splitter cable to split the left/right channels.  Plug the splitter cable into your sound card's headphone socket. Then plug your amplified speakers into the left output socket and your headphones into the right.

  1. In the Audio Settings tab, choose the following:
    • Output: Speaker + Headphone
    • Card: Stereo to Mono Splitter
    • Master: Set to your soundcard - Chan 1 (mono)
    • Headphones: Set to your soundcard - Chan 2 (mono)
  2. Click Apply to complete.
