Conditions of this configuration;

lease read care

ull

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 provides a visual depiction of a system that utilizes

the limited quantity of any-type configuration. Some of the sources also include

digital audio. 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.

Cable between level 1 and level 3

is in place.

Nine jumpers are removed from

their original location and stored

on the jumper holder.

**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.

COMPONENT SOURCES:

PHYSICALLY CONNECT TO LEVELS 1, 2, & 3

(INPUTS 9 THROUGH 16) ONLY.

DIGITAL AUDIO (IF AVAILABLE):

PHYSICALLY CONNECTS TO LEVEL 4 AND IS

SWITCHED WITH COMPOSITE, S-VIDEO, OR

COMPONENT SOURCES, BUT NOT ON THE

SAME INPUT NUMBER.

EIGHT (OR

MORE) COMPOSITE

SOURCES*

ARE PERMITTED.

EIGHT (OR

MORE) S-VIDEO

SOURCES**

ARE PERMITTED.

UP TO EIGHT

COMPONENT

SOURCES ARE

PERMITTED.

NOTE:

THE LABELING OF INPUTS 17

THROUGH 24 BECOMES USEFUL

WHEN PROGRAMMING.

NOTE:

THE SAME IS TRUE FOR PAIRED INPUTS 2&18,

3&19, UP TO 8&24. HOWEVER, WHEN

PROGRAMMING DIGITAL AUDIO, USE THE

INPUT NUMBER LESS THAN 8.

DIGITAL AUDIO CAN ONLY BE DISTRIBUTED

FOR A TOTAL OF 16 SOURCES. IF DIGITAL

AUDIO IS DISTRIBUTED WITH THE S-VIDEO

DEVICE CONNECTED TO INPUT 1, INPUT 17

WOULD BE PROHIBITED FROM USING LEVEL

4 FOR DIGITAL AUDIO (AND VICE VERSA).
