OPERATION ORBAN MODEL 8685
For example, if the 2B B
REAKPOINT
is set to 10
DB
, the release rate (in dB/second) will
be constant when the gain reduction is above 10 dB. Between 10 dB and 0 dB gain
reduction, the release rate will slow down more and more.
The calibration of the B
REAKPOINT
controls is only accurate when K
NEE
= 0 dB and/or
R
ATIO
= infinity:1 — i.e., when the compression ratio is essentially infinite. When the
ratio is less than infinite, the effective breakpoint of the compressor will be lower
than
2B B
REAKPOINT
setting.
The main use of the
2B B
REAKPOINT
control is to prevent the compressor from objec-
tionably increasing audio density when using low compression ratios and a signifi-
cant amount of gain reduction—for example, 10 dB. The
2B B
REAKPOINT
control is
best adjusted by ear. If you find that density increases too much as gain reduction
increases, lower the
2B B
REAKPOINT
control’s setting. If you want more density at
high amounts of gain reduction, increase the
2B B
REAKPOINT
control’s setting. 10 dB
