Installation and
Calibration
DC-1 Digital Controller
In the absence of an SPL meter, it is possible to set the output level by ear.
Use the internal noise generator in the DC-1 to adjust all volumes to be the
same as they cycle around the various speakers. Depending on timbre
variations between your speakers, this may be difficult to judge — get as
close as you can. The system should be reasonably well balanced, although
not actually calibrated for precise playback and level matching. With the
system volume at 0dB, the internal noise source should be at the same level
at which film dialog sounds comfortable.
Mute Level
This menu allows you to set the level of attenuation used whenever the
DC-1 MUTE function is engaged. In the Output Levels menu, select
attenuation levels of -10dB, -20dB, -30dB, -40dB, and FULL.
Power On Volume
This control in the Output Levels menu allows you to select the volume at
which the DC-1 will power on. You can choose from a range of -80 to +12dB,
or elect to have the system power on at the level it was at when powered off
(LAST LVL).
Note that the ZONE2 output always resets to 0dB when the DC-1 is turned
off. This power volume setting is not adjustable.
