The ML-800 is a dedicated 8-room audio control system for the hospitality industry. Based upon the venerable ML-116, the ML-800 promises unprecedented functionality and ease of use in a very affordable package.   The ML-800 can control up to 8 rooms with single button ease of use. Room combining is done via the front panel. Additionally, all individual room functions can be performed from the front panel making it possible to set-up and monitor the entire facility from a single location.  Unlike most other systems, ML-800 is truly an out of the box plug and play system. There simply is no programming required or modules to assemble. Attach the wall plates from each room, the mixers and the amplifiers, and the ML-800 is ready to go.  The ML-800 goes beyond simple room combining system by providing distribution and control of 4 background music sources as well as paging. In room control is accomplished with either a membrane wall plate or a color LCD touch screen. The wall plate or touch screen can control the background music source and volume as well as the foreground audio volume. When rooms are combined, any changes made to one room automatically track to all combined rooms. A key switch or security code is built into the wall plate to prevent unauthorized changes from taking place.
