The 6565 control unit is designed to control Johansson products through the coaxial cable. Many products, such as Profilers, Combiners, Multiswitches, etc., can be managed with this device. Thanks to the clear OLED display and easy adjustment with the rotary button, configuration is very easy. One great advantage is that you can control the Profiler from anywhere in the building. Simply connect the control unit to the nearest output and you will be able to adjust the Profiler or compatible products, e.g. 6520, 6550A, 6555A, 6556A, 6557A.
