Conditions of this configuration;
please read carefully!
This configuration allows for up to 24 sources. However, those sources cannot
exceed more than eight component, more than 16 S-video (assuming no component
sources), more than 24 composite (when there is no S-video and no component). The
illustration after this paragraph depicts a system that utilizes the limited quantity of
any-type configuration. Notice that component sources can only be connected to
input 9 through 16 (levels 1, 2, & 3) and that S-video sources can only connect to
input 1 through 8 (levels 1 and 2). Installation of the cable assembly and removal of
jumpers splits level 3 (thus component sources are restricted to inputs 9 through 16)
and extends level 1 with eight composite-only connections. Of course, if there are
fewer than eight component (or eight S-video) sources in the system, the number of
S-video and/or composite sources can increase as long as the total number of sources
does not exceed 24.

WHEN PROGRAMMING.
*COMPOSITE SOURCES CAN CONNECT TO
LEVEL 1, INPUTS 1 THROUGH 8
(WHEN THERE ARE LESS THAN
EIGHT S-VIDEO SOURCES).
COMPOSITE SOURCES CAN ALSO CONNECT
TO LEVEL 1, INPUTS 9 THROUGH 16
(WHEN THERE ARE LESS THAN
EIGHT COMPONENT SOURCES).
HOWEVER, THE TOTAL NUMBER OF
COMPOSITE, S-VIDEO, AND COMPONENT
SOURCES CANNOT EXCEED 24.
COMPONENT SOURCES:
PHYSICALLY CONNECT TO LEVELS 1, 2, & 3
(INPUTS 9 THROUGH 16) ONLY.
**S-VIDEO SOURCES CAN CONNECT TO
LEVELS 1 OR 2, INPUTS 9 THROUGH 16
(WHEN THERE ARE LESS THAN
EIGHT COMPONENT SOURCES).
HOWEVER, THE TOTAL NUMBER OF
S-VIDEO AND COMPONENT
SOURCES CANNOT EXCEED 16. REFER TO THE LOGICAL DEPICTION
(SHOWN BELOW) OF THE PHYSICAL
CONNECTIONS (SHOWN ABOVE).
S-VIDEO SOURCES**:
PHYSICALLY CONNECT TO LEVELS
1 & 2 (INPUTS 1 THROUGH 8).
