Light Mixer Panel

This highly affordable eight-channel light mixer panel has all of the standard control features plus extras such as a switchable rhythm generator for the control inputs and optical output voltage indicators. Furthermore, the circuit is designed to accommodate extensions, in particular external control signals originating from a PC.A light mixer panel forms the heart of every lighting installation in a theatre, concert hall or discotheque. The days when lighting control was limited to the legendary ‘lights out, spot on’ are far behind us. For some time already, lighting has been regarded as an integral part of the performance. A light mixer panel is just as important for the lighting as an audio mixer panel is for sound. The job of the light mixer panel is to provide the control signals for the various dimmer/lamp combinations; it acts as a sort of ‘user interface’ between the responsible technician and the lighting installation.
