Date: 6/18/02
When replacing an SDEC Digital Equalizer, as an alternative to using the Loader
utility, the flash memory chips on the DSP Engine inside the SDEC, which contain the
programmed filter, delay and crossover settings may be swapped. With SDEC1000/A
swapping flash chips is a more reliable method of transferring files to a replacement
unit. Follow the procedure below to swap SDEC.d97 file settings.
1. Remove the malfunctioning SDEC from the equipment rack.
2. Remove the SDEC top cover.
