Distance units controls whether the “Distance setup” screen shows speaker distances in feet or meters.
OSD Output gives you the choice of sending on-screen display information to the composite
video OSD output, the S-video OSD output, both, or neither (“Off”). If you set this for an output
you’re not using, or to “Off,” all OSD information (including background color) will disappear
from your OSD screen. However, you can then restore OSD by using the display and controls
on the C 2 front panel.
OSD style changes the colors of the OSD text, background, and error messages. There are
30 possible settings; the default is white lettering on dark gray, with error messages in white
lettering on red. We recommend dark gray instead of a colored background to extend the life of
TV monitors and front or rear projectors that use CRTs (cathode-ray tubes).
Trigger Setup
Many home theater components (including amplifiers, retractable screens, and some lighting
equipment) can be controlled by DC trigger signals. The C 2 has three trigger outputs, two of
which, P1 and P2, are programmable through this setup screen:
Trigger sense defines the event or condition that you
wish the C 2 to sense in order to generate a trigger volt-
age. A few examples are: the moment when the C 2 is
turned on, whenever the remote Zone is turned on, activa-
tion of its display dimmer; the presence of a composite
video signal, an S-video signal, or whichever comes first; a
change of video source (except component video) or any
audio source, or selection of any specific source (including
the 7.1-channel input and whichever source is assigned to
the balanced input).
Polarity does not change the trigger jack’s + output to – and vice versa, as its name implies.
Rather, it selects whether the individual trigger output is normally off or normally on. When
Polarity is set to “Posit.” the triggering event you selected will switch the trigger output from
0 to +12 volts; when set to “Negat.,” the triggering event switches the trigger output from
+12 to 0 volts. Each trigger output can deliver up to 200 milliamperes (200 mA) of current.
Delay adjusts the delay between a triggering event and the actual trigger signal output. It
can be set for “No” delay or for any of 14 delays, of 1 second to 3 minutes.
Duration controls the trigger signal’s duration. The trigger signal can be set to remain active as
long as the triggering condition applies (“Infin.”) or to any of 16 periods from 10 milliseconds
to 3 minutes. If duration is set to 10 ms or 100 ms, additional pulses of 10 ms and 100 ms are
generated when the triggering event ends. This enables the C 2 to control devices that require
separate turn-on and turn-off pulses.
The third trigger, marked “On-Off” on the rear panel, only operates when the C 2 is turned on
and off. It is set for positive polarity, no delay, and “infinite” (continuous) duration.
Thanks to the flexibility of its three triggers, the C 2 can initiate and end a number of operations.
For example: the “On-Off” trigger could be used to turn power amplifiers on and off with the C 2;
video-based settings could be used to lower a projection screen, turn on a video projector, dim
room lights, and draw window curtains.
