cause density increases as the control is turned up. Listen carefully as you adjust it.
With these fast release times, there is a point beyond which increasing the Five-Band
compressor drive will no longer yield more loudness, and will simply degrade the
punch and definition of the sound. Instead, let the AGC do most of the work.
Because excessive loudness is an irritant in sound for picture, there is almost never
any reason to push processing to the point where it degrades the audio. We recom-
mend no more than 10dB gain reduction as shown on the meters for Band 3. More
than 10dB, particularly with the fast release time, will often create a wall of sound
