The SDI/HD-SDI video input is available only on the ISS 506 DI/DVI, the
ISS 506 DI/SC, and the ISS 506 DI/HD-SDI.

Although all video formats can be physically connected, input 6 cannot accept
multiple video inputs simultaneously.
Audio input connections
e
Input audio connectors — Connect balanced or unbalanced stereo or mono
audio 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 2-6 shows how to wire a connector for the appropriate input type.
Use
the supplied tie-wrap to strap the audio cable to the extended tail of the connector.
High impedance is generally over 800 ohms.

The length of the exposed (stripped) portion of the copper wires is
important. The ideal length is 3/16" (5 mm). Longer bare wires can
short together. Shorter bare wires are not secure enough in the direct
insertion connectors and could be pulled out.

When making connections for the seamless switcher from existing audio cables,
see figure 2-7. 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 2-6.

The audio level for each input can be individually set via the front panel, the
Ethernet link, or the RS-232/RS-422 link, to ensure that the level on the output
does not vary from input to input. See chapter 3, “Operation”, chapter 4,
“SIS
Programming and Control”; and chapter 5, “Scaler Software”, for details.
