Consumer Level Analog Audio Signals; Rs-422 Remote Device Control - Blackmagic Design H.264 Pro Recorder Manual De Instalación Y Funcionamiento

HDMI provides the same uncompressed, digital quality as high-end SDI digital video but
at a much lower cost. It is designed to be used over short distances and standard cables are
typically only 6 feet or 2 meters in length. HDMI is often found on consumer equipment as well
as on some professional equipment. The HDMI cable can be directly connected to the HDMI
port on H.264 Pro Recorder.
SDI and HD-SDI provide industrial grade connections for uncompressed, digital video. SDI
cables support transmission of uncompressed digital video over at least 300 feet or 100
meters. SDI and HD-SDI connections are found on high-end broadcast and professional video
hardware. An SDI or HD-SDI cable can be directly connected the SDI / HD-SDI port on H.264
Pro Recorder.
How Does H.264 Pro Recorder Know Which Input Connections to Use?
H.264 Pro Recorder auto-detects the video input you wish to use, i.e. SDI, HDMI, component,
S-Video or composite analog video. For this reason, only connect one video source to H.264
Pro Recorder so it can auto-detect which source to use. If you are using analog video, you can
also connect analog audio at the same time as expected. The RS-422 remote connection does
not affect video input auto-detection.

Can I Use H.264 Pro Recorder with Consumer Level Analog Audio Signals?
Yes and no! H.264 Pro Recorder is designed to work with professional, balanced, analog audio
equipment. It does not work directly with unbalanced, consumer level analog audio. In order to
capture unbalanced audio from consumer equipment, a third party balancing transformer with
line level converter can be used.
It is not necessary to buy an expensive balancing transformer. Low cost models exist and do a
great job and typically cost around US$65.

RS-422 Remote Device Control

H.264 Pro Recorder features an industry standard, Sony™ compatible, RS-422 deck control port
which has the correct pin connections for a direct connection to any deck.
You can use pre-manufactured 9 pin cables as long as each end of the cable are wired "pin for
pin" where the same pin number on each end of the cable are connected together. If you would
like to make custom cables, e.g. for extra length, please refer to the accompanying
wiring diagram.
