Main H949 Panel
Line
When the Line control is IN the unit is actively processing audio;
when it is OUT the unit is bypassed and passes audio directly
from input to output.
Input Level
This is used to set the optimum operating level for the system.
The knob acts as a conventional volume control. Five level indi-
cators provide visual cues as to the actual level of the incoming
signal. In normal operation, the yellow
PRESENT
LED indicates
that a low-level signal (
-60dBfs
) is being applied to the input.
The 3 green
NORMAL
LEDs illuminate in sequence (
-12 dBfs
,
-6dBfs
,
-3dBfs
) to indicate a minimal driving signal, and increas-
ing levels within the normal range. The red
LIMIT
LED lights
within
0.5 dBfs
of clipping. Note that all of these indicators are
peak-responsive and will light on ”peaky” material even if the
average signal level is quite low. The ideal setting will drive all
of the green LEDs, with no flashes of the red LED. Note that the
level indicators are after the feedbacks, i.e. they measure
Input
+ Main Fe Delay Only Feedback
, to indicate any digital
clipping at the pitch shifter input.
