3.2.6 To Read Audio Volume Units (VU) of output #1
This command returns the height of hypothetical bar LED indicator having a
height of 16 segments. It will return a number from 0 to 16 with 10 being 0 db
level. So if the output #1 is at 0 dB (900 mv p-p sinewave) it returns 10. See
figure 11 for 16x16 row. This value is 0-16 regardless of the type of matrix.
