custom compression modes. The default setting for RF Overmodulation Protection is disabled. This parameter is not available on the DP567.

Input Level Meter

Input Level Meter shows the input signal that the compressor is using to determine 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.
