The Botex DMX Controller SDC 6 I bought for the control of DMX enabled RGB LED spotlights. Connection is made via a 3-pin cable with XLR plug or socket at both ends (eg microphone cable). Both used radiator types (Euro Lite LED Par 56 DMX Aluminium and IMG Stage Line PARL-1DMX) can be connected easily and drive. When PARL-1DMX with 4 DMX channels first 3 channels of the controller control the 3 primary colors and the master channel, the overall brightness or, depending on the basic setting of the radiator, some spotlight effects. When Euro Lite with 6 DMX channels over 6 the slider can control the 3 primary colors, the overall brightness as well as the built-in functions of the radiator. The Botex DMX Controller SDC 6 fulfilled in my experience everything it promises and is therefore a low-cost controller for easy DMX applications.
