In the above table, “Yes” implies that the PIP arrangement is normal and could be used during a capture
session. “Duplicate” implies that the Main image and the PIP image are identical, and this arrangement
would normally not be used. The “No” entries are present because the HDMI-1 and DVI-D conflict on the
digital input. The Comp entry allows simultaneous use of RGB on the VGA connector with component
input on the DVI-A connector.

The Dual Input (secondary stream) is limited to full-screen HDMI-2 or SDI. No PIP or overlay operation is
provided for on this window.

8.3.1. Audio Connections
There are six audio input connectors on the chassis, Microphone (low-level), Line (high-level), Balanced
(stereo), HDMI-1, HDMI-2 and SDI. This control selects the primary audio input source.
8.3.2. Audio Microphone Gain
The audio microphone gain adjusts the signal level from the microphone to the input of the audio codec.
A reference signal of –40.0 dBu ( 7.75 mV RMS) will produce maximum sample values when the Mic
Gain is set to a value of approximately 90. If this is considered the internal 0.0 dB signal reference, the
chart shows gain adjustments for different values of Mic Gain.
