Feedback code description:
- A5 C3 3C 5A FF 63 04 04 00 00 AC FE EE means device main volume is -34.0dB
- A5 C3 3C 5A FF 63 04 04 02 04 EC FF EE means Output 4 volume is -2.0dB
To calculate dB volume value from hex answer:
- =HEX.N.DEC(A1 & A2) / 256
- Example 78 00:
- A1 is MSB (78) .
- A2 is LSB (00) .
Voor 78 00 levert dit:
- 30720÷256=12030720 \div 256 = 12030720÷256=120
- Divide this answer by 10 to get 12dB in this example
Example A8 FD:
- Hexadecimale value: A8FD → 432614326143261 (unsigned decimaal).
- 43261÷256=−60043261 \div 256 = -60043261÷256=−600.
- -600/10= -60dB
