Io 4K Plus Capture, Display, Convert v14.0r2 19 www.aja.com
You can choose 2-wire or 4-wire input and output (depending on the type of
signal). If the number of links selected is not sufficient, the number of links is
automatically increased to accommodate the signal. UltraHD or 4K SDI signals 30
fps and below can be input and output simultaneously, using two connectors in
each direction. However, all four connectors are required above 30 fps. You will be
able to either input or output a high frame rate SDI signal, not both at the same
time. In this situation, you can use the down-converted SDI monitor output to
monitor the input signal, or use the HDMI output. Note that to monitor incoming
UltraHD/4K SDI as HDMI UltraHD/4K, the SDI input transport must be 2SI. Quad
SDI will be down-converted to HD on the HDMI output.
Specifying the number of wires for output forces Quadrant mode. You cannot
specify the number of links when 2SI output is selected (the lowest number of
links will be set automatically).
Io 4K Plus Audio Monitoring
Io 4K Plus hardware can be used as your single audio monitoring solution
whether you are auditioning music in a web browser, playing a movie file on
the desktop, creating music, or playing a YouTube clip. As long as the output of
your work or application is normally output via the host system audio, your AJA
hardware can route this audio for monitoring. This cuts down on unnecessary
cabling, and means you can take advantage of a consistent audio monitoring
environment whatever you are currently doing with your host system.
NOTE: On first use, you will need to tell your operating system to use AJA hardware as
the default Input and Output hardware.
Io 4K Plus lets you listen to Host System audio concurrently with your NLE audio.
This is useful if you need to audition music tracks against playback of your NLE
timeline, or if you need to Skype with a remote producer during an edit session,
or for a myriad of other reasons.
You can also listen to Io 4K Plus Input concurrently with your NLE (with the
exception of Avid Media Composer). This is useful if you need to listen out for the
readiness of talent, or the presence of some other feed, whilst you continue to
work.
Io 4K Plus audio monitoring is routed and mixed using the Control Panel
application's Audio Mixer screen. You can select sources to be monitored, and
can adjust their levels. If you are using the 1/4 inch monitor output connector, an
additional overall mix gain control is conveniently available on the Io 4K Plus's
front panel.
The mixed audio monitor signal is also routed to:
• SDI Audio out
• HDMI Audio Out
• Analog Audio Out (via DB25 cable)
IMPORTANT: Even though you can hear changes in the signals and levels adjusted with
the Audio Mixer screen, these changes are NOT recorded to disk during NLE
Capture or Audio Punch In / Voice Over to Timeline. The Audio Mixer screen is
dedicated for monitoring only, not program mixing.
