Product Description
The Blue Box is automatic in its operation and may be installed by any competent electrician. It is connected between the electrical consumer unit and the mains sockets used to supply power to the amplifiers. A microphone detects the level of sound within the room; if the sound level rises above the (user adjustable) pre-set threshold, the unit trips, removing power from the amplifiers. After twenty seconds the Blue Box automatically resets and restores the power.
The front of the unit features a series of LED's which like a traffic light go from green through orange to red; thus acting as a warning, enabling the operator of the sound system to keep the volume below the trip threshold.
