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: 1. Hexadecimale value: A8FD  432614326143261 (unsigned decimaal). 2. 43261÷256=-60043261 \div 256 = -60043261÷256=-600. 3. -600/10= -60dB
