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' by toggling switch 1. Component analog video supports both HD
and SD video.
The switch legend on the base of your converter gives you all the
information you need to change conversion settings.
Switch 4, 3 and 2 – SDI Audio De-Embed
Switches 4, 3 and 2 are represented as bits 2, 1, and 0 respectively. This simply means that by
setting various on/off combinations for switches 4, 3, and 2, you can choose which pair of audio
channels from your SDI or optical input you would like to output to analog or AES/EBU audio.
Switch 1 – Processing Off – Processing On
Switch 1 lets you change the aspect ratio conversion that occurs when down converting Ultra
HD or HD inputs to SD analog outputs. This occurs because Ultra HD and HD formats are
presented in a 16:9 widescreen ratio of width to height, whereas SD is a taller 4:3 ratio.
The three options for aspect ratio conversion you can toggle through here are anamorphic,
center cut and letterbox. These stretch, crop, and add black bars to the top and bottom of your
image, respectively. To switch between these, simply toggle switch 1 on and off to move
through the available options. Each time switch 1 is set to 'on,' the aspect ratio type will move
ahead one option.
The behavior of switch 1 also changes depending on the analog output format you are using.
Composite video is always standard definition, so setting switch 1 to 'off' simply leaves the last
aspect ratio conversion option in place. However, component video can support a HD signal, so
when you are converting video from an SD source to a component output, setting switch 1 to
'off' will output a widescreen HD analog signal, with no aspect ratio conversion.
