Switches
Mini Converter SDI to Analog 4K’s switches provide the following settings:
Switch 8 - Analog Audio, AES/EBU Audio
Set switch 8 to OFF to select balanced analog audio, or to ON for digital AES/EBU audio output.
Switch 7 - 7.5 IRE - 0.0 IRE
The USA and countries using NTSC with 7.5 setup should set switch 7 to OFF. If you’re working
in countries not using 7.5 setup, set switch 7 to ON. This setting only affects composite or
S-Video outputs.
Switch 6 - SMPTE Levels - Betacam Levels
Set switch 6 to OFF for SMPTE levels, or ON for Betacam levels. SMPTE levels are more
common and even Betacam SP decks can use SMPTE levels, so only switch this to Betacam if
you are sure that Betacam levels are being used.
Switch 5 - Component, Composite or S-Video
Set switch 5 to OFF to select analog component video output, or ON for composite and
S-Video outputs.
To display the HD video input as SD on the S-Video and composite outputs, down conversion
must be set to ON. Component analog video supports both HD and SD video.
Switch 4, 3 and 2 - SDI Audio De-Embed
Switches 4, 3 and 2 are grouped together to provide 8 ON/OFF combinations. Having eight
different combinations allows eight independent pairs of audio channels to be de-embedded
from your SDI input.
Switch 1 - Processing Off - Processing On
Down conversion with 3 types of aspect ratios by cycling through switch 1. Each time you cycle
between Off and On you apply anamorphic, center cut or letterbox aspect ratios.
For both HD and Ultra HD input, set switch to OFF to output HD analog via the
component outputs.
Set switch to ON and Ultra HD input downconverts to either analog PAL/NTSC or HD
component depending on the other switch settings. 4K DCI will be cropped on the component
HD output.
An ON setting with HD input will be downconverted to analog PAL/NTSC or component
depending on the other switch settings.
When connected to Blackmagic Converters Setup via USB, your down conversion settings are
controlled by the software. If you want the converter to remember your software settings,
disconnect from the computer, power cycle your converter and set your down conversion
using switch 1.
