MixWizard4 mixers can be fitted with an optional high quality audio card that will send 16 audio channels to a computer for recording or processing and a return stereo channel for monitoring or effects.

The card neatly mounts within the rear pod of the WZ4 mixer and the data is available from a USB2 connector at the rear of the mixer. Switches on either side of the USB2 connector allow the users to change routing options.
