4CONTROL CENTRE LBB 1280 At the heart of each SM30 sound management system is the Control Centre. This is a self contained unit, housing the microprocessor which controls SM30, and

12slots which hold the plug-in modules. On the front panel of the Control Centre are programming keys and associated LEDs, an alpha-numeric LCD display, and keys for controlling the functions of the music source inputs. The versatile construction allows the Control Centre to be mounted free-standing on a table top, or with other equipment, in a 19” rack. All of the interconnections between individual modules take place automatically when they are plugged into the interconnection board of the Control Centre, so that no complex inter wiring is required. Thanks to the unique construction of the housing, the modules slide in and out quickly and easily. These features make SM30 simple and inexpensive to install and maintain. All switching and routing of the system is carried out by software, so that hardwiring problems are kept to a minimum. This means that though SM30 comprises a great amount of features, making it a comprehensive Public Address Centre, the unit itself is uncluttered and simple to assemble and use.
