The Digital Interface Standard recommends D/A converters have a minimum Input sensitivity of 200 mV. In early FL8300 production units, the Digital Output level was 240 mV ±10% peak to peak. Based on our research, we found that some D/A converters require more than 240 mV for intermittent free operation. - Page 23 In the event you receive a FL8300 from a consumer with a complaint “Player will not read or, loudspeakers make strange noise while playing multimedia CDs”, replace IC112 with H/K Part number 2139322722. The IC can be identified by CXP82320-367Q DPW 325B printed on its case.
