OPERATION ORBAN MODEL 6300

Escape button provides an escape from current screen and returns user to the
next higher-level screen. Repeatedly pressing Escape will always return you to
the Idle screen, which is at the top level of the screen hierarchy.

Input meters show the peak input level applied to the 6300’s analog or digital
inputs with reference to 0 = digital full-scale. If the input meter’s red segment
lights up, you are overdriving the 6300’s analog to digital converter, which is a
very common cause of audible distortion.

AGC meter shows the gain reduction of the slow, 2-band AGC processing that
precedes the multiband compressor. Full-scale is 25 dB gain reduction. You can
switch the meter (within the Full Modify screen) so that it either reads the gain
reduction of the Master (above-200 Hz) band, the gain reduction of the Bass
band, or the difference between the gain reduction in the Master and Bass
bands. This control is located in
M
ODIFY
> F
ULL
M
ODIFY
. The meter mode always
reverts to M
ASTER
when the user leaves Full Modify.
The latter reading is useful for assessing the dynamic bass equalization
that the AGC produces and it helps you set the
AGC BASS COUPLING
control.

Gate LED indicates gate activity, lighting when the input audio falls below the
threshold set by the multiband gate threshold. When this happens, the multi-
band compressor’s recovery time is slowed drastically to prevent noise rush-up
during low-level passages.

Gain Reduction meters show the gain reduction in the multiband compressor.
Full-scale is 25 dB gain reduction.
When the 5-band structure is operating, all five meters indicate gain re-
duction.
When the 2-band structure is operating, the B1 meter indicates gain re-
duction in the Master band and the B2 meter indicates the gain reduc-
tion in the Bass band.
When the processing is in dual-mono mode, the gain reduction meters
can be toggled between channel 1 or channel 2 via
S

ODE
or,
when you are in the Main screen, by pressing the P
REV
button for chan-
nel 1 and the N
EXT
button for channel 2. Meanwhile, the PC Remote ap-
plication displays both channels’ gain reductions simultaneously.

Multimeters (The rightmost pair of meters) indicate the gain reduction of the
AGC or Multiband channel look-ahead limiters in units of dB (see page 6-41 for a
block diagram of the processing), or the action of the High Frequency Enhancer
and Stereo Enhancer processing, in arbitrary units. The user can select the de-
sired mode via
