Stewart Audio's Control and Reporting Application allows the user to discover, setup, control, and receive status information on all network controlled MC850 Amplifier products. It also allows the user to update the device firmware as new releases are available. This program discovers all MC850 models, allows monitoring of input or output signal levels, and provides channel-by-channel and master trim and mute functions. Sleep mode settings can be configured. The control port IP address can be set to DHCP or fixed. Power can be allocated among the channels (LZ and MXZ models). There are real-time temperature indicators, as well as amplifier fault status and logging.
All these functions are easily configured and displayed via an intuitive, uncluttered, graphic-driven PC application. Windows 7 or higher operating system is required. A wired or wireless connection to the network can be used.
