About the DX-700
auJTMM=fåéìí=fÇÉåíáÑáÅ~íáçå
With digital inputs (DVI or SDI), the DX-700 can accurately identify the source’s format and
resolution. Typically, no user adjustments will be required to fully acquire the image.
Please note:
• DVI inputs are typically RGB; however, some sources can provide DVI in the
YC
b
C
r
colorspace. Because there is no clear way to distinguish between RGB
and YC
b
C
r
DVI inputs, the colorspace defaults to RGB for computer resolutions,
and YC
b
C
r
for HD video resolutions. If the default colorspace is incorrect, the user
can select the correct colorspace.
• Analog inputs cannot always be accurately identified, but the DX-700 will
sufficiently acquire any valid source and provide a visible image at the output.
User input may be required to set the exact input timing and colorspace details.
• Automatic input identification may not always be accurate for some modes of dual
HD-SDI input. In this configuration, user selection will be required.

The DX-700 enables you to switch inputs. Please note:
• Using the internal mixer on each input module, seamless transitions can be
performed between inputs, as long as the new (incoming) source is valid and
stable. Transitions through black can also be performed.
• External source switching can also be performed:
~ During the “external” switching process, any video output derived from
the source goes black if the sources being switched are asynchronous.
~ When sources are synchronous (such as genlocked cameras), the
switch through black will be minimal.

supports computer resolutions. It does not support SD / HD
resolutions. The three BNC connectors (
YUV) can accept
composite, S-Video or Component input.
