CD player with digital audio impact recovery, variable over easy compression, and ambiance control. #7 condition with worn lettering on front but no scratches. In shop use. This is an obviously worn unit. We leave the listing up because we still service and supply parts. This unit is special because of nice audio imaging circuits. It is a Kyocera Cybernet CD design with DBX processing of audio. Be aware this early era CD player design will have trouble playing damaged discs or most CDR. We tweak them up to do better, but it's error correction circuits (apart from DAC) are not powerful enough to play problem discs. The alternative is any later (1990's) JVC, Sony, Pioneer which will run all discs and you could add on a DBX 1BX to create the same sonic effects. No doubt DBX image enhancement devices are very useful and versatile.
