Hot Wax DJ Player for iPhone and iPod touch requires a stereo splitter.
Here's a picture of an inexpensive one we like to use. The product is called an Audio Channel Separation Adapter. Basically what is does is split the stereo signal output by your device. This way you can plug in your headphones into into the LEFT output jack, and send the RIGHT to your amplifier or mixer. The product can be purchased from Circuit City at http://www.thesource.ca/estore/product.aspx?language=en-CA&product=2740396
There are many, many different ways to build your own splitter however. Remember, the software pumps out the audio for what's CUED to the LEFT channel. The RIGHT channel is the MAIN out, whose content is controlled by the crossfader.
So all your splitter needs to do is allow you to plug your headphones into the left channel, and pass the right channel as your main out to your mixer or amp.
