SET UP AND OPERATION the threshold, the signal is reduced in level, relative to the amount the signal exceeds this point. This gain reduction is set by the ratio control. Fig 1 The interactive relationship between the operating level and the headroom It is possible to further improve the audio quality by constantly monitoring the programme material with the aid of a volume fader, which manually levels the material. During low passages the gain is increased, during loud passages the gain is reduced.
