Input Configuration
The MC-1 has eight inputs, each of which can be associated with any
of the eight video and eight digital audio inputs. Selecting Input Configu-
ration 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 Gain (Analog Inputs Only)
For optimal performance when using analog inputs, the unit must be
driven to its full input level without clipping. Despite industry attempts at
standardization, different analog sources have a wide range of output
levels. To compensate for this, each of the eight MC-1 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 indicated by an enlarged tick mark on the Input Level
meters.
The MC-1 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.
