Can anyone suggest a method to disable the Low Pass Audio Filter on an Amiga 2000 through hardware? I do have the PD program to turn the LED power light on and off (turns the filter on and off) but I also have a couple of sample music programs that "blink" the light and therefore continuously disable and enable the filter. They were meant for an Amiga 1000 (where there is no software method to disabling it). I want to be able to disable and enable the filter by a simple method of adding a jumper, etc. to the board.

Listen closely to the sound output; and if you hear a change in the quality, the program has been disabled. Otherwise, you have nothing to worry about. -- cknight@polyslo.calpoly.edu ---King Claudius---

Huh? That's how you control the low pass filter... with the LED line. >Listen closely to the sound output; and if you hear a change in the quality, >the program has been disabled. Otherwise, you have nothing to worry about. You _will_ hear a change if you are running anything that changes the LED light level while music is playing on a 500 or 2000. -larry -- Van Roy's Law: An unbreakable toy is useful for breaking other toys. +----------------------------------------------------------------------+ | // Larry Phillips | | \X/ lphillips@lpami.wimsey.bc.ca or uunet!van-bc!lpami!lphillips | | COMPUSERVE: 76703,4322 | +----------------------------------------------------------------------+
