Kurzweil K2600 K2600S K2600X K2600XS K2600R K2600RS (Negative) LED Display !

Description: LUX Custom LED display upgrade ! Specifically designed for various Kurzweil instruments. White on Blue available. Plug N Play ! In the following Kurzweil K2600 Series. K2600 K2600S K2600X K2600XS K2600R K2600RS Contrast and backlight brightness, are both fully adjustable. Contrast, is controlled in the normal way. The ideal setting is around mid-way of the adjustment range on every K2600 variant. Optimal ! Backlight brightness can be adjusted via a small potentiometer on the display. Accessible from above, in between the display / interface PCB. To dim the backlight, turn the potentiometer clockwise to dim or anticlockwise to brighten. If required. (see listing pictures) This special custom display is a 2-piece design. Essential, to sort out the design faults of the old Tianma display, which through time, cause it to malfunction. The standard Tianma display is a flawed design. It should never have been used by Kurzweil in any of these instruments. Producing the display in 2-pieces, means all the critical display dimensions, can be fully optomised. This is important to maintain consistent bezel pressure during the entire lifespan of the display. 20+ years. The malfunctioning, associated with the standard Tianma display, will NOT happen again. Manufacturing this way, is more complicated, time consuming and expensive. A lot of additional engineering was required, which ofcourse, like everything at the shop, has been done to the highest possible standards. For example, all the mounting points and fasteners are beautiful machined brass, knurled and passivated. NO cheap off the shelf fasteners / parts were used in the production of this display. Note ! The existing back panel brightness control will NOT work with an LED backlit display. It's ballast circuit is designed to work with CCFL via (AC) voltage potential principals. (Cold Cathode Florescent Lamp) The cathodes in CCFL lamps heat up toaround 200 degrees. This is one of the design flaws of the old display, this heat source, sat inside the display, basically, cooking it. It's one of the reasons why the old display, eventually, malfunctions. Upgrading to LED backlight, solves the CCFL heat problems, as LED's are much more efficient, but the existing (AC) backlight dimmer circuit for the old display is not compatible with a modern LED display. Instead, You must use the dimmer built into the LED display. It sits in-between the display and mounting board. During display installation, adjust with a small screwdriver. Simply turn (continuously) clockwise to dim, one or two turns, If the backlight is too bright for your taste. Couple of turns, will take the edge of the brightness. The potentiometer is only a 2k. As a result, the adjustment is smooth/linear not glitchy. It's easy to dial in the exact brightness you want. it's meant to be set up once, then forgotten ! Installation of this display is very simple ! It bolts in and connects by its ribbon only ! Nothing else is required ! Plug N Play ! **This listing is for one ( 1 ) Plug N Play display only**
