Depending on your network throughput capabilities and other traffic, and of course your production
requirements, you may choose to leave this option off when it is not required.
Note: Multiple connections to UHD video can quickly saturate a gigabit network. Use the 4K option only when
it is really needed. And if many 4K connections are required, consider using the Multicast setting (although
this requires special care when configuring the network – see Section 2.5.1).
The current video format the device has negotiated with your source is displayed at right.
AUDIO INPUT
FIGURE 2-10
Just below, you will see the Audio Input group (Figure 2-10). It is comprised of two buttons, labeled Digital
and Analog. These determine whether Spark Pro uses the embedded audio source (digital audio included
with the HDMI video source) or analog audio supplied to Spark’s 1/8” line level stereo input connector. Spark
Pro’s nominal audio level is +4dBu.

The second tab in the configuration web page is labeled Administration. Here you will find information and
settings related to your Spark device, and its network connection.
