primary danger is that the excessive drive will cause noise to be increased excessively
when the program material becomes quiet. You can minimize this effect by activat-
ing the single-ended noise reduction and/or by carefully setting the M
T
control to freeze the gain when the input gets quiet.
HRESHOLD
When the release time of the 5-band compressor is set towards fast, the setting of
the M D
ULTIBAND RIVE
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 5-band com-
pressor 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
effect that many find fatiguing.
To avoid excessive density with fast 5-band release time, we recommend using no
more than 5dB gain reduction in band 3, compensating for any lost loudness by
speeding up the AGC R
MB REL ("Multiband Release") control can be switched to any of seven settings. To
