  • Page 2: Mono Input Module

    mono input module direct output features This section is intended for use in Front of House operations to provide a controlled feed to an external tape machine. It may also be used as a localized effects send or monitor output. When the console is being used for monitor mixing operations, this output is used as a dedicated send to the Matrix section to generate custom versions of the Matrix mix for monitor use by secondary artists such as horn sections or backing vocals.
