The Allen & Heath ZED-24 features sixteen mono and four stereo inputs in a compact system. Each XLR input comes complete with the Allen & Heath DuoPre pre-amps, which break down the gain range into two stages to keep unwanted noise to a minimum. The 3-band EQ design utilizes Musiq, which provides equalization for each instrument. With the  USB input, you can easily connect this mixer to your computer to record and download your mix or to play a previously recorded signal or any other type of music into the current mix.
