The LED stripe is glued e.g. to the inner edges of the cases A-100P6\/P9\/PMS6\/PMS9\/PMS12 to illuminate the modules and patching statically or dynamically. Especially during live events the dynamic illumination in sync with the sound is an eye-catcher. Each color (red, green, blue) has available a manual control for the background brightness and a CV input with attenuator that enables the dynamic brightness controlled by other control voltages of the modular system. For example three envelopes can be used which also control the loudness or filtering of sound processing modules. But even other control applications are possible, e.g. LFO, random voltages, clock\/gate\/trigger signals, sequencer, Midi-to-CV.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-family: Arial; font-size: small;\"\u003eThese are the most important features of the module:\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan style=\"font-family: Arial; font-size: small;\"\u003eControl module for static or dynamic control of RGB LED stripes\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-family: Arial; font-size: small;\"\u003eSo far RGB LED stripes with 1m and 2m length have been tested.

From the factory the trimming potentiometers are adjusted so that the LEDs of the stripe are just dark when the manual controls are fully CCW and no external CV signals are applied (or the CV attenuators are also fully CCW).\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-family: Arial; font-size: small;\"\u003eBoth the control electronics and the LEDs are very fast so that it's possible to realize even fast optical effects. To obtain e.g. a strobe effect all manual controls are fully CCW, all CV controls are fully CW and only CV input CVR is used. Then one obtains (nearly) white light pulses when short envelope signals or rectangle signals with small pulsewidth are used for CVR (e.g. the master clock signal).\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-family: Arial; font-size: small;\"\u003eSupply via the built-in power supply of the case or external (wall-art) supply to avoid the additional current consumption for the LED stripes.

For example the A-100P6\/P9\/PMS6\/PMS9\/PMS12 are suitable. The aluminium rails of the case should be cleaned befor the LED stripe is sticked on the rail. The low-cost cases (A-100LCx) are not suitable without modifications because the rim is too small and the self-adhesive stripes do not stick very good at the raw wood or the coating of the vintage versions. One would have to modify the low-cost cases e.g. by adding a metal or plastic band with at least 10 mm width from the hardware store to glue the LED stripes.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-family: Arial; font-size: small;\"\u003eAn external 12V supply has to be ordered separately if required (5.5\/2.1 mm connector, plus = center).
