INTRODUCTION The Allen and Heath 16.4.2 is a highly compact and lightweight Mixing Console which incorporates all the facilities normally required for live sound mixing and for multi-track recording. Up to six separate outputs can be used by utilising the direct output sockets of each of the four sub-groups, as well as the main stereo outputs. This will provide six different mixes - often useful when mixing theatre sound. In the studio, the 16.4.2 can be used in conjunction with a stereo recorder and a multi-track recorder. Metering and monitoring can be switched from the console to any tape input by using the channel routing push-buttons.
