Numark C2 DJ Mixer Our simplest, most easy-to-understand design, C2 is a powerful rack DJ mixer. There’s no finer mixer value in terms of performance, features, or quality. Five-band EQ lets you tailor system response to the room with precision. The sophisticated microphone section includes great tools such as auto-ducking, which automatically drops the level of whatever’s going on when announcements need to be made and auto-muting with sensitivity adjustment so feedback will be nothing but a distant memory. In a world of mixers with overly-complex designs and unnecessarily complicated operations, C2 delivers a new way of mixing with great value and ease of use.
