Blackmagicdesign ATEM Live Installation And Operation Manual page 22

ATEM switchers feature a 'ref in' connection to offer low latency synchronization of feeds
between compatible equipment. If you are using an external reference source such as
Blackmagic Sync Generator or Blackmagic HyperDeck Extreme 8K HDR, connect the reference
signal from your sync source to the 'ref in' BNC connector.
If you're plugging a computer with HDMI compatibility into the HDMI inputs of an ATEM switcher,
then be sure that the monitor settings on the computer are set to the correct resolution and
frame rate. For example, if you are using 4320p video, then your monitor needs to be set to
4320 x 7680 resolution, and if using Ultra HD 2160p video then set your monitor to
3840 x 2160. For 1080i your monitor should be set to 1920 x 1080. Alternatively, if you are using
HD 720p video, then set your monitor to 1280 x 720. NTSC should be set to 720 x 486, and PAL
needs to be set to 720 x 576. The frame rates also need to match.
NOTE It's important to know that HDMI cable quality can vary, so we recommend
buying good quality cables, and high end video resellers will stock a range of high
quality cables. Good quality cables will help eliminate unwanted sparkle or glitches in
HDMI video inputs.
If you don't see video on a HDMI video input, even though you have a device connected,
then you might want to check if the HDMI device you have connected uses HDCP content
protection. This content protection actually encrypts the video data in the HDMI video cable,
so the manufacturer does not allow the content to be seen on anything other than a television.
You won't be able to see images from these devices. Devices with HDCP content protection
include DVD players, and set top boxes.
In general, cameras and computers don't have content protection, so you should not have any
problems connecting these devices. Some gaming consoles don't include HDCP content
protection, however generally these are only the developer versions of these gaming consoles.
Using the analog component input of a Mini Converter Analog to SDI or the analog component
input on an ATEM 1 M/E Production switcher to connect devices is a good work around in
these situations.
Always be sure you have copyright ownership before using or displaying content publicly.
On 1 M/E, 2 M/E and 4 M/E switcher models you can connect a remote camera head and control
it using pan, tilt and zoom controls with the joystick on an ATEM hardware control panel. Refer
to the 'using ATEM hardware panels' section in this manual for more information on setting up
PTZ control.
Plugging in Audio
Your ATEM switcher includes a built in audio mixer which allows the use of embedded
HDMI and SDI audio from your cameras as well as external audio from the dedicated analog
audio or MADI inputs. Depending on the ATEM switcher you are using, these may be XLR,
1/4" jacks, RCA or MADI BNC inputs. These audio inputs can be used for other audio sources
such as camera microphones and pre-recorded audio.
See 'using audio' for more on connecting additional audio sources.
