OPERATION ORBAN MODEL 6300
Note that the multiband gate only works appropriately when the K
NEE
and R
ATIO
controls of all bands are set identically, which is typically the case in broadcast appli-
cations. We recommend turning off the multiband gate if the individual
K
NEE
and
R
ATIO
settings are unequal.

B1/B2 Crossover (Band 1 to Band 2 Crossover Frequency) sets the crossover fre-
quency between bands 1 and 2 to either 100 Hz or 200 Hz. It significantly affects the
bass texture and the best way to understand the differences between the two cross-
over frequencies is to listen.
Transient Enhance is mainly useful in mastering. This control allows you to insert
an audio delay in the sidechain of the 5-band compressor. By delaying the gain con-
trol signal, this allows attack transients to pass through the multiband compressor,
which can increase punch. There is a tradeoff between this control and the activity
of the look-ahead limiter, which will have to eliminate attack transients exceeding
the look-ahead limiter’s threshold. For any material, there will be an optimum set-
ting for the
T

NHANCE
control that provides the most punch without trig-
gering look-ahead limiter artifacts.
Loudness Threshold See page 3-43.
Test Modes
The Test Modes screen allows you to switch between O
PERATE
, B
YPASS
, and T
ONE
.
When you switch to
B
YPASS
or
T
ONE
,
the 6300 saves the preset you had active and
will restore it when you switch back to
O
PERATE
.
Even if you had been editing a pre-
set and did not yet save these changes as a User preset, you will not lose the edits
you made.
Table 3-12: Test Modes shows the facilities available, which should be largely self-
explanatory. The test modes function identically in stereo and dual-mono modes. For
example, in dual mono mode, setting
T
ONE
C
HAN
to L
EFT
applies signal to channel 1
but not to channel 2.
