3-4
Rear Panel Operation Mark Levinson
Figure 3-4: Component Input Card. These three wires contain a single luminance signal (a black-and-
white version of the picture), along with two color difference
signals. The color, or chrominance, “components” of component
video are sometimes called by different names, but for your
purposes they all mean the same thing. Whether U or V, Cr or Cb,
or Pb or Pr, it equates to the same thing: terrific quality (and three
wires).
For your convenience, we have also supplied several BNC-to-RCA
adapters, which lock into place with a quarter-turn of the BNC half
of the adapter. These adapters effectively convert the professional
BNC to the more common consumer RCA.
Slots 5 through 7 can accept a wider variety of types of video signals
than can Slots 1 through 4.
Connect any component outputs that you plan to use from your
video components to these component inputs on the Nº40. Make
sure that the three wires do not get crossed up, as the resulting
picture will look positively bizarre if you do confuse things. Keep
track of which source components are plugged into which connec-
tors on the rear panel of the Nº40, either by keeping a list or by
making a note on the Hookup Chart at the end of this manual.
See “The Define Input Menu” on page 5-31 for more information
on defining your inputs.
Video Input
Expansion
As shipped from the factory, slot 8 is normally empty except for a
blank piece of metal that covers the opening. This slot can be used
for an additional component input immediately, should you
require one, or for other types of advanced video inputs in the
future. Slots 8 is electrically identical to slots 5 through 7.
Video RZone
Expansion
As shipped from the factory, slots 9 and 10 are normally empty
except for a blank piece of metal that covers the opening. These
slots can be used for the video portions of additional Remote or
Record zones (“RZones”) immediately, should you require them.
The RZones are counted from right to left; hence slot 9 is reserved
for RZone 4, and slot 10 is reserved for RZone 3.
In addition to their current application for RZone use, slots 9 and
10 also have digital video input and output capability.
Video RZones 1 & 2
As shipped from the factory, slots 11 and 12 are normally used for
the video portions of the two standard Remote or Record zones
(“RZones”).
