Installation and
Calibration
The input level meters are displayed when
you select the GAIN parameter for an
active input which has been selected in
the Setup menu.
Although you are given the option of defeating the auto level system by
selecting MANUAL, this is not recommended. 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 MENU ▲ 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.
When GAIN is selected, two on-screen horizontal bar meters display peak
incoming signal level. The highest peak level is shown in dB in a separate
text line, and as an arrow in the the meter display. White, yellow and red
sections of the bar meter show increasing levels. The white portion is shown
in 3dB increments, the yellow and red portions are shown in 1.5dB incre-
ments. An enlarged block at -21dB indicates the reference level used with a
Dolby calibration tone source.
The peak level display can be refreshed by pressing DONE to exit, then
pressing SELECT to return to the display.
Input Level Meters
Input Name
Restore Input Name
Each input has an associated name which is displayed during normal
operation whenever the input is selected. The default names correspond to
the labels on the DC-1 remote control and the front and rear panels. These
names can be customized to more accurately reflect your system configura-
tion.
To assign a new name (up to 8 characters) for an input, select NAME from
the Input Configuration menu, and EDIT INPUT NAME from the sub-
menu. The display will show the current name with a cursor marking the
character position to be modified. Use the MENU ▲ and ▼ buttons to select
a new character for that position, and SELECT to move the cursor to another
position. Press DONE twice to return to the Input Configuration menu.
This control allows you to restore the factory name for the currently selected
input. Pressing SELECT displays the message PRESS SELECT TO RE-
STORE INPUT NAME. Pressing SELECT again restores the name and exits
to the Input Configuration menu.
