OPERATION

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
reverts to M
ASTER
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
Meanwhile, the PC Remote application displays both channels' gain re-
ductions simultaneously.
