Type GSWL-SR22    Main Controller

GENERAL
This is a 1U subrack and provides the main control and intelligence for the whole system. It is mains powered. Drawing number A2-14180 shows the front and rear views of this unit.
It is basically a DSP with up to 16 RS422 ports presented on the rear panel as RJ45 connectors. In this application only 12 of the ports contain chips.
Each RJ45 connector can also provide power for external units. The power output is a nominal 12 volts. The current to each RJ45 connector is limited to 500mAs with a resetable fuse.
In addition to the rear panel RJ45 connectors there are also two phono connectors. These send and receive data to a VHS recorder. This data includes the individual mic levels at each of the mic amps. This facility is included to enable us to check and improve the automatic mic selection algorithm.
