CONNECTIONS
SOURCE-COMPONENT AUDIO SIGNALS
1. Audio Output of Source Components to the A4.6Ci
Male-to-male RCA audio cables connect the four exter-
nal audio sources.
2. Buffered-Cascade Audio Output of Source
Components to Slave A4.6Ci’s or a Home Theater
Male-to-male RCA audio cables connect Slave A4.6Ci’s or
the Home Theater.
TELEPHONE PAGING
3. Paging Output of Telephone System to A4.6Ci
Page Input
A male-to-male RCA audio cable connects the paging
output of a telephone system to the A4.6Ci.
SYSTEM EXPANSION
4. System Expansion Input to System Expansion Output
Four-pair twisted cable, terminated with male RJ-45
plugs, connects multiple A4.6Ci's using the System
Expansion Input and Output terminals. Connections are
made from the input of one of the A4.6Ci's to the output
of another, and so on. (For more information on
Terminating Four-Pair Twisted Cable, refer to page 39.)
SOURCE-COMPONENT POWER AND HOME THEATER
SYNCHRONIZATION SIGNALS
5. 12V Home Theater Sync to Home Theater Sync Input
The 12V Home Theater sync signal connects with a
mini-plug to the Home Theater sync input.
6. Video Synchronization from a Source Component
to an A4.6Ci Sync Input
An RCA Y-adapter is used to split the video output of a
source component for connection to one of the two
source sync inputs of the A4.6Ci (1 or 2). One side of the
RCA Y-adapter connects to the appropriate source sync
input and the other side connects to the intended desti-
nation for the video signal (i.e., the video input of a TV,
receiver, or RF modulator).
The need for an RCA Y-adapter can be avoided if your
video source has two video outputs. One video output
connects to a source sync input and the other to the
intended destination of the video signal.
Important Note: Source sync inputs are designed with
high-input impedances so as not to affect the quality of
the video signal when using an RCA Y-adapter.
