Dear Sir,
We checked AIC3110 DRC have some questions need your help,
Register:
Page0 REG68 0x44( DRC Control 1) | Enable |
Page1 REG38 0x26 (Left Analog Vol to SPL) | 91 |
Page1 REG42 0x2A (SPL Driver) | 0C |
Page0 REG65 0x41 (DAC Left Volume Control) | 30 |
Page0 REG71 0x47 (Left Beep Generator) | 02 |
Result:
When input is -1dB, o/p will trigger DRC and stable to 2.1Vrms.
When input is 0dB, o/p will trigger DRC and stable to 2.2Vrms.
Question:
Why increase i/p level trigger DRC but o/p level is different?
As my thinking, once trigger DRC, no matter input level, o/p should keep the same level, isn't it?
Thanks, Ian.
