the amount of boost or cut. This signal is derived by taking the largest of the
individual channel signal levels and then attenuating by the dialnorm amount (see
Section 4.1.7).

Line Mode and RF Mode
Line Mode
and RF Mode meters show the current value of the cut and boost words
being included in the Dolby Digital bitstream. Red shows compression (cut) and
green shows boost, calibrated in dB. Line mode represents a two-channel decoded
output designed for connection to a stereo hi-fi, for example, RF mode represents a
signal designed for re-modulation onto an RF carrier.
