About the Operating Modes
There are five different Monarch LCS
operating modes:
Single Isolated , Dual
Isolated , Switcher , Picture-in-Picture ,
and Side-by-Side .
Depending on the Operating Mode you
select, the settings under the Video and
Audio sections will change, and certain
modes (e.g. Picture-in-Picture ) will add a
Layout section.
The following are conditions where the final frame rate options are limited:
• In Dual Isolated mode, when your sources are at 50 or 60 fps, your (HDMI
out) preview (of the sources) will display at 30 fps.
• In Dual Isolated , Switcher , Picture-in-Picture , and Side-by-Side
operating modes, the encoding frame rate is dependent on the frame rate of
the Input A source. For more information on frame rates, see
“Frame rate”
on page 41 .
¡ Important Please note the following:
• Before starting a session, it is recommended to unplug an input cable
connected to an unused input. An invalid signal can affect production (the
session).
• It is recommended that interlaced sources always be connected to Input A.
Configuring video and audio settings
The Video section includes the selectable video input and output settings. You
can switch between inputs in the Command Center; however, only after a
streaming or recording session has been stopped. If you attempt to switch the
inputs while encoding, the stream/recording will have to be stopped, and the
session will have to be restarted to encode from the new input.
The Audio section is where you set the source for your audio input ( Analog or
Digital ), the sample rate, and the bit rate. Monarch LCS supports a stereo pair of
audio for streaming and recording, and whether you are using an SDI or HDMI
source, only the first two channels are selected by the device for encoding
(see
“Video/audio inputs and outputs” on page 9 ). However, all 16 audio channels
from SDI sources are available when output through SDI out. Monarch LCS uses
the AAC audio format for streaming and recording. To monitor the selected audio
source, you can use any of the audio outputs (SDI, HDMI or analog).
Please note the following about the Audio settings:
• Sample Rate. You can select the desired sample rate for either your digital
or analog audio input source.
