[. . . ] The middle button is an exception because it allows the entry into the Setup Menu by pressing it for 5 seconds. Comment: The DMX as well as the analogue input works normally as before. -LOCK 4. 4. 7 DELETE ALL (set all to default) "Delete All" deletes all memories, chases, DMX addresses, curves, etc. The DMX address will be set to "1" and the "Block" Mode is activated. Be careful in using this function, because it may be hard work to reprogram all functions. 10 MA Lighting Technology GmbH . www. malighting. de Digital Dimmer 4. 4. 8. and 4. 4. 9 CURVE USER (User definable control curves) Here the setup menu for the control curve 1 and 2 can be activated. Individual brightness curves can be programmed, just as necessary for a lamp. Later on these curves can be assigned to the dimmer channels. In the curve menu the encoder changes the position of the cursor in the x-axis (input); when the right button is pressed, the y-axis (output) can be modified. Y X Example 1 (linear): Here the connection between input (lighting control desk) and output (lamp) is linear and 1:1. For normal use this simple curve is adequate. Example 2 (logarithmic): The output (lamp) reacts even at low input values. Example 3 (exponential): The output (lamp) reacts very little to small inputs, but all the more when the input is higher. Example 4: Lamp does not react till input is at 50 % , but in this case reacts linear. Example 5: Lamp is controlled inversely. If the input is 0 % , the Lamp is activated to 100 %, if input is 100 %, the lamp is off (0%). 4. 4. 10. (activate phase angle correction) Usually this control parameter is set to "ON". It makes a brightness-linear light control possible. The normal non-linearity, produced by the SRC´s phase angle control, is thereby compensated. This function works in addition to the "User Curves". This function should only be deactivated ("NO"), when this correction is made internally by the control desk (e. g. MA Lightcommander I) and cannot be switched off. MASTER/SLAVE (coupling of dimmers) For coupling several dimmers, the master and slave part can be defined. For this function a 5 wire DIN cable must be used; MIDI cables often have only 3 wires!(cannot be used yet) This parameter makes it possible to send out DMX data of the dimmer and read them externally via the DMX interface. [. . . ] Don´t use any high-power walkie-talkies near the unit. Don´t service the unit yourself as parts that are live might be exposed when you open the case; you run the risk of getting shocked. All services should only be carried out by a specialist. If one of the following conditions occurs, please pull the plug out and call the service: A. [. . . ]
