11.7 Using the side
chain filter as EQ
This is an unusual application as it does not use the DPR 944 as a compressor.
Each compressor channel of the DPR 944 contains a good quality wide
ranging parametric filter. This filter can be accessed by depressing the
side
chain listen
switch, passing the output of the side chain filter to the main
output. If the DPR 944 is used in this way, none of the compressing features
for that channel will be available, and no controls other than those for the
filter will be operable.
11.8 Creative use
All the previous examples deal with using the DPR 944 for some kind of
corrective action, and indeed it is a powerful tool for dealing with problem
sounds. There is also great scope for using the unit for special effects, as it has
the power to radically alter the characteristics of instruments in a unique and
creative way. Unfortunately, this is very difficult to describe - as always it's
best to play!
For starters, try using a large amount of compression at infinite ratio while
sweeping the
frequency
control from one end of the band to the other. Try this
with different
width
settings, and don’t forget to let us at BSS Audio know
about any unusual applications you may find .....
With some program playing, depress the
side chain listen
switch. By
manipulating the sound system level and DPR 944
frequency
and
width
controls, find the frequency band that is causing problems, and then make this
band as narrow as possible. Ensuring that the
threshold
control is
out
, release
the
side chain listen
switch and increase the system sound level until there is
unacceptable distortion. Rotate the
threshold
control until the distortion is
diminished. Try different ratio and filter settings.
11.6 Dynamic bass
and treble
enhancement
In a club situation, the bass and treble content of the program can be made to
appear louder without increasing the overall sound level if the middle
frequencies of the program are reduced when the sound level approaches the
limit. This is done with the
stereo link
mode enabled (remember to set both
channels frequency and width controls the same). Set the
threshold
on
channel 1 so that the
gain reduction
light start to come on at the desired
level. In this application the
width
control need to be made quite wide. The
ratio
control will probably need some manipulation.
