Connections for Various Input Video Formats

Input audio connectors — Connect balanced or unbalanced stereo or mono audio
sources to these 3.5 mm, 5-pole captive screw connectors. Connectors are included
with the seamless switcher, but you must supply the audio cable. Figure 5 shows how
to wire a connector for the appropriate input type.

Captive Screw Connector Wiring for Inputs
ATTENTION: The length of exposed wires is critical. The ideal length is 3/16 inch
(5 mm).
•
If the stripped section of wire is longer than 3/16 inch, the exposed wires may
touch, causing a short circuit between them.
•
If the stripped section of wire is shorter than 3/16 inch, wires can be easily
pulled out even if tightly fastened by the captive screws.
NOTE: When making connections for the seamless switcher from existing audio
cables (see figure 6). A mono audio connector consists of the tip and sleeve. A
stereo audio connector consists of the tip, ring, and sleeve. The tip, ring, and
sleeve wires are also shown on the captive screw audio connector diagram,
figure 5.

Typical Audio Connectors
The audio level for each input can be individually set, via the front panel, the Ethernet
link, or the RS-232 link, to ensure that the level on the output does not vary from
input to input. See the applicable portions of the “
” section (see page 18),
” section (see page 45), and “
” section (see
page 54).
