Mini Converter SDI to Analog 4K

Change your converter's internal settings by adjusting the
mini switches using the tip of a pen.
Mini Switches
Mini Converter SDI to Analog's mini 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 the Blackmagic Converter Utility 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 mini switch 1.
