Table 68 Analogue Bias Control
BIAS CONTROL
Table 69 Analogue Bias Control
The analogue amplifiers will not operate unless BIASEN is enabled.
Control of the analog bias values is possible using register 61 and 62
Note that these bits must be used with care and may cause degradation in analog performance. For
example, if both BIASCUT and HALFDACI are used at same time, the playback THD will be poor.
