27 12G-SDI In
The 12G-SDI input is used for connecting to a switcher or external recorder and can be
used to view playback, talkback, tally or external reference signals. When used with an
ATEM switcher, you can also adjust the camera functions using the switcher’s ‘camera
control’ feature.
If you’re using URSA Mini in a live broadcast, you can plug in the switcher’s program
output and monitor it during the shoot, or check playback from an external recorder.
Press and hold the ‘pgm’ button to see the program feed. For more information, refer
tothe ‘control buttons’ section for URSA Mini or ‘ergonomic control panel’ section for
URSA Mini Pro 4.6K.
To receive tally and talkback via the SDI input, make sure you have set your ATEM
Camera ID in the camera’s setup menu. If you want to use the SDI input to receive an
external reference signal, you will need to select ‘program’ as your reference source in
the setup settings. ‘REF’ will appear next to the timecode display on your camera’s LCD
screen when the external reference is locked. Refer to the 'setup settings' in the manual
for more information.
On URSA Mini Pro 4.6K the SDI Input can be used for feeding external timecode to the
camera as well. This will lock to the incoming timecode automatically if the frame rate of
the incoming SDI signal matches and has valid timecode. The 'EXT' logo will appear on
URSA Mini Pro 4.6K's LCD when external timecode is locked. If you unplug the cable
timecode will remain jammed and the logo will switch to 'INT' to let you know it is now
running from URSA Mini Pro's internal timecode clock.
28 Reference and Timecode In
This input automatically recognizes and switches between timecode and reference
input signals. Synchronize Blackmagic URSA Mini to a common reference signal, such
as tri-level sync, by connecting to the ‘reference’ BNC input marked ‘REF In’. It's worth
noting that to use a reference signal through this input, you must set your reference
source to 'external' in your URSA Mini's setup menu.
You can also use this connector to match an external timecode source to sync up
multiple cameras, or audio and picture when shooting dual-system. This ensures audio
and picture, or video from multiple cameras, can be easily synchronized during post
production. When external timecode with a matching frame rate is plugged into this
connector the camera will lock to the incoming timecode automatically. The 'EXT' logo
will appear on URSA Mini's LCD when external timecode is locked. If you unplug the
cable, timecode will remain jammed and the logo will switch to 'INT' to let you know it
isnow running from URSA Mini Pro's internal timecode clock.
You can also set your camera to use the reference signal from an ATEM switcher via the
SDI Input. This is helpful when working with ATEM switchers because all cameras can
receive program return, camera control, tally, talkback, reference and timecode using
asingle SDI signal. See the 'setup settings' section in this manual for more information.
29 12V+ Power Input
Use the 4 pin 12-20 Volt DC XLR connector to plug in power from external sources such
as the supplied power adapter, or portable batteries.
30 Headphone/Headset
The 3.5mm jack output is used for headphone monitoring and talkback. You can plug in
iPhone and Android compatible headsets that have a built in microphone for quick and
easy talkback. Talkback audio is embedded in channels 15 and 16 of the SDI output.
