Dynamics Input Controls
The dynamics input controls—labeled "INPUT"—allow you
to manipulate the audio signal as it arrives at the dynamics
section:
•
IN GAIN (dB)—sets the volume of the
signal entering the dynamics section.
•
D-TIME (ms)—allows you to slightly
delay the signal arriving at the
dynamics processors from 0-10 ms
(milliseconds). A longer delay allows
the MTK more time to analyze the
audio signal, resulting in more accurate
dynamics control. This is known as
"look-ahead" processing.
•
LO (Hz)—determines the low-to-mid
frequency split point for the multiband
processors. This can be set from 20 Hz
to 800 Hz.
•
HI (Hz)—determines the mid-to-high frequency split point
for the multiband processors. This can be set from 1600 Hz
to 16000 Hz (16 kHz).
The dynamics input controls are always active, even if the individual
multiband processors are bypassed.
Careful adjustment of the split points allow you to zero in on specific
mix components (kick drum/bass guitar, lead vocals, cymbals, etc.) for
subsequent multiband dynamics processing. 120 Hz for the low split and
4000 Hz for the high split are good starting points. After adjusting the
multiband processors, however, you'll probably find that you need to
readjust the split points to get the sound "just right."
The Multiband Processors
The multiband expander and multiband compressor look
nearly identical. Each processor has its own graphic dynamics
display, and a column of gain reduction meters that indicate
the current amount of gain reduction for each band.
Under each display, there's a row of four onscreen knobs for
controlling the processor. On the left side of each display,
there's a column of switches for selecting a band for editing, as
well as a switch for bypassing the entire processor.
Multiband Expander (EXP)
The first multiband processor is the expander, or "EXP. " The
expander works by reducing the volume of signals that fall
below a specified threshold.
The expander contains the following controls:
•
ON/OFF—turns the expander on (lit) or off (unlit).
•
LO, MID, and HI—selects the desired band for editing.
•
THRE (dB)—sets the threshold for the selected band. The
threshold value can be set from -80 dB to 0 dB.
