Extron electronic DSC HD-3G A, DSC 3G-HD A manual B Input connector, E Audio input connector, Sync

AAC power connector — Connect the supplied US standard IEC power cable between this IEC connector and a 110-220 V 50-60 Hz AC power source. The front panel control and input selection buttons light in sequence during power-up.

BInput connector —

•DSC 3G-HD A: Connect a 3G/HD/SD-SDI source to this female SDI BNC input connector.

•DSC HD-3G A: Connect an HDMI source to this female HDMI input connector.

CBuffered loop-through connector — Connect a local monitor to this female SDI BNC input connector. Buffered 3G/HD/SD-SDI signals are reclocked, reshaped, and restored when passed through this loop-through connector.

DGenlock sync connectors (DSC HD-3G A only) — Connect an external sync device to the female BNC input (left) connector to sync the video signal in broadcast or other sync-critical applications.

Connect any downstream equipment that requires genlocking to the female BNC output connector (right) to route the sync signal throughout the system in broadcast or other sync-critical applications. Bi-level and tri-level sync are supported.

Input Output

•DSC 3G-HD A: Connect audio from the source to this 5-pole captive screw connector. Analog audio input can be embedded on the HDMI output. AES audio that is embedded on the SDI input can be identified and one to four pairs (8 channels) of the available 16 channels can be embedded on the HDMI output:

•If eight-channel digital is selected, four of the eight available channel pairs are used.

•If two-channel digital is selected, one of the eight pairs can be selected.

•DSC HD-3G A: If desired, connect analog audio input from the source to this

5-pole captive screw connector. HDMI or analog audio can be passed through to the SDI outputs as AES pairs.

Figure 5. Wiring the Audio Input Connector

ATTENTION:

•The length of the exposed wires in the stripping process is critical. The ideal length is 3/16 inch (5 mm). If the exposed portion is longer, the wires may touch, causing a short circuit between them. If the exposed wires are shorter, they can be easily pulled out, even if tightly fastened by the captive screws.

•Do not tin the wires. Tinned wire does not hold its shape and can become loose over time.

•For unbalanced audio, connect the sleeves to the ground contact. Do not connect them to negative (–) contacts.
