Signature 2.0
Video Detect
This option line permits you to select whether the 2.0
will continually search for incoming video, or if the
circuits for automatic detection will be turned off.
In normal operation, the factory default setting of AUTO
should be left in place. When AUTO is in use, the unit’s
video board will periodically examine the signal at the
selected video input to see if there are any video sync
pulses, indicating the presence of an incoming signal. If a
signal is detected, it will be displayed on the screen, with
the on-screen menus superimposed over the video image.
When no video signal is present, the on-screen menus
and messages will be displayed over a blue screen.
The AUTO setting will work for most sources. However,
in some cases, the incoming signal may occasionally be
weak due to poor-quality video playback, tapes with bad
tracking, or other factors. If those conditions are present
on a particular source, such as a VCR, selecting the OFF
option will stop the auto search for video sync, permit-
ting the menus to be displayed regardless of the incoming
sync quality. As always, the blue screen will appear when
no video is present.
NOTE: As with all source-related settings, the Video
Detect setting is for the input being adjusted only. To
permanently disable the option of showing video under
the menus, change the Menu Bkgrnd setting to Blue
in the Display Options menu of Advanced
Settings (see page 36).
To make a change in this option, press the

next step.
Input Level Adjust
When an analog input is selected, the next step is to
set the input level. Correct input level adjustment is
needed so that the surround sound processing circuitry
has both enough information to decode, and to make
certain that the information in both input channels is at
the same level. This level setting does not involve the
actual output volume that you hear, but rather the small
voltages that embody the signals sent from the output
of a source unit and the input of the 2.0. Different
products may have widely varying output levels so it is
important that you set the input level to assure proper
surround processing.
Since digital audio signals do not vary in level with
changes in program material intensity, they are trans-
mitted at a constant bit rate. For that reason, it is not
necessary to set the input level for digital audio sources.
Accordingly, this step does not appear on the
Source
Menu
when a digital input is selected as shown below
(Figure OSD-6).

Before setting the input levels, make certain that the
source machine you are adjusting is in the play mode,
using program material that is representative of your
favorite listening choices. Remember; the actual volume
setting is not important here, rather, you are concerned
with the electrical interface between the two units.
