Orban 5750 Technical Manual
•
MULTIBAND DRIVE – Sets the level applied to the multiband compressor and thus its average level of gain
reduction.
•
MULTIBAND RELEASE – Sets the release rate for the multiband compressors.
•
DOWN EXPANDER – Downward Expander. Sets the threshold that triggers single ended noise reduction.
•
B5 DOWN EXPANDER STEREO COUPLE – Fine tunes the downward expansion to be coupled or independent
stereo.
•
MULTIBAND GATE THRESHOLD – Determines the lowest input level that will be recognized as program.
•
B1/B2 CROSSOVER – Sets the crossover frequency between bands 1 and 2.
•
BAND COUPLING – There are 5 controls for band coupling. These controls determine the amount one band will
track another. In the scenario "Band X>Y Coupling", "X" will always follow the gain reduction of "Y".
•
MAX DELTA GR – Governs the mount of independent stereo gain reduction in each band. 0 is coupled (the
channel with the most gain will reduce both channels). OFF means the channels are never coupled.
Take care to watch the gain reduction meters while adjusting this stage. In the HTML5 application you will see
the differences between left and right play out in the gain reduction of the metering.
The same holds true for coupling. If you notice too much bass in your audio (for example), you may notice only
a little gain reduction in Band 1 vs Band 2. By increasing the coupling between Band 1 and Band 2 (B2>B1 control)
you will see more gain reduction in Band 1 relative to Band 2. Adjust to the desired amount of bass and set. You
will now have a more consistent tonal balance between Band 1 and 2 suitable for your format. The same can be
applied to the other bands of gain reduction as well.
