Input Configuration
The DC-2 has eight inputs, each of which can be associated with any of the
five video and eight digital audio inputs. Selecting Input Configuration
from the Setup menu displays a sub-menu which lists these inputs and
allows you to select them individually for adjustment. Each input has an
identical parameter sub-menu. V-DISC is shown below as an example.

INPUT CONFIG
For optimal performance when using analog inputs, the unit must be driven
to its full input level without clipping. Despite industry attempts at stan-
dardization, different analog sources have a wide range of output levels. To
compensate for this, each of the eight DC-2 analog inputs can be assigned
a different input gain, assuring optimum performance regardless of the
source. For use with a calibration tone, the Dolby reference point is indi-
cated by an enlarged tick mark on the Input Level meters.
The DC-2 GAIN function can be set to AUTOMATIC to monitor the analog
input level and automatically optimizes the input gain. If the signal level is
too high, input gain is automatically decreased to a point which does not
cause clipping. When the signal level remains low (>12dB below clipping
for 2.5 minutes), the input gain is increased in 1dB steps to maximize
dynamic range.
When MANUAL is selected, the display shows the last auto level setting. (If
the auto level feature has not been used, the display shows the last manually
entered level.) The auto level setting indicates the optimum input level
value as determined by the unit. The ▲ and ▼ buttons increase or decrease
the input gain in 1dB increments for the selected input over a range of -18dB
to +12 dB. The setting is displayed in dB along with horizontal bargraph
meters on the on-screen display to indicate incoming signal level.
Note that if a level is set manually, then AUTOMATIC is engaged, the level
will not go above the last value entered manually.
