Secondary Monitoring:
The HDMI signal is used to show the secondary display which is a represen-
tation of the image recorded, it shows up without user interface and can be
turned on and off inside SiliconDVR user interface. The HDMI Port at the SI-2K
Recording Unit carries a DVI Signal (1280 x 720 @ 60Hz). By using off-the-
shelf HDMI to DVI Converters every kind of DVI Monitor can be fed.
There are manufacturers who provide solutions to convert the resulting DVI sig-
nal to HD or SD SDI video signal (i.e. Doremi DSDI-20 ). Please be aware that
the SI-2K is rather designed as a Digital Cinema Camera than for purposes as
a video camera.
Notes on the HDMI Port:
If your DVI or HDMI monitor does not work instantly at the HDMI Port, please
quit SiliconDVR application and manually restart it again. If it still does not work,
the output device does not support given resolution and/or frequency. Please
also note, that using the HDMI Port instead of splitting the VGA signal for moni-
toring slows down overall performance !
Audio
Audio input is provided on the 15-pin 'D-sub' connector at the top of the elec-
tronics bay. An adapter cable terminates in two XLR connectors for stereo
microphone inputs and two XLR connectors for stereo output. Note that these
are not balanced inputs and should only be considered for scratch audio. Inter-
nal acquisition runs at 16 bit, 48 KHz per channel.
For quality recording, the M-Audio MobilePre external audio interface has been
tested and is compatible with the SI-2K. Other audio devices are not sup-
ported by the camera and SiliconDVR.
A 1/8" stereo headphone jack for sound monitoring is provided to the right of
the microphone connector.
