Pioneer DJM-900 Nexus
This 4-channel blender has all the inputs and outputs you could wish for. Per channel, you can choose between line in/CD input and one input for the turntable. There is a separate rec output and balanced booth outputs.
The DJM-900 is perfectly integrated with DJ software and Tractor 2. In addition, the blender also has a built-in 96kHz/32-bit sound card, which means that the sound quality is improved compared to little brother DJM-800.
