ABSTRACT:
A digital audio gain control system has an operator interface with a CPU, RAM storage, and input devices for a user to store transfer characteristics relating gain to be applied to an incoming audio signal to the signal strength of that incoming signal. A communication link allows the transfer characteristic function to be sent to a RAM in a separate patchable amplifier unit having a DSP and RAM, and level detection circuitry for monitoring the signal strength of an incoming audio signal and applying gain according to the transfer characteristic communicated to the on-board RAM. The amplifier unit also sends operating information back to the operator interface, where operation may be displayed to aid an operator in adjusting the function.
