In the Pvw/Key/Fill mode you must supply a valid video timing reference signal to
the unit. You can provide either an analog video signal into the REF input BNC or a
serial digital video signal to the INPUT BNC. The input signal must be running the
same video standard as required by your downstream switcher or keyer.
section 2.5.3 and 3.6.2 for information on connecting and selecting the video timing
reference signal.
The PREV output contains the video output from the preview and will normally be connected to a SDI
monitor to allow you to view the program output before it goes on air. When the bypass relay is active,
the PREV output will not have any video on it.
2.5.3. Video Timing Reference
For proper timing of the video and audio signals an analog video genlock reference may be supplied.
Connect a composite analog NTSC or PAL colour black video signal to the REF IN connector. Make
sure that the signal type is correct for the video standard in use. (See Table 2-6 and Table 2-7)
Alternately you can take the timing reference from the input video. The Video reference source is set
using the Reference Setup menu item on the GENERAL Setup menu. (See section 3.6.2)
On early HD9625LG units that do not have the REF IN connector the timing
reference is always taken from the Video Input.

CONNECTING THE AUDIO (9625LGA AND HD9625LGA ONLY)
The 9625LGA series Media Keyers are capable of working with either embedded audio or discrete AES
audio. The HTML Audio Setup page is used to select the embedded or discrete AES audio inputs as
the background or main audio source for the AES and embedded audio outputs. (See section 3.11.1)
The audio available on the AES PROG outputs is embedded into group 1 and 2 on the PROG video
outputs. The audio available on the AES PREV outputs is embedded into group 1 and 2 on the PREV
video output.
The HTML Audio Setup page is also used to select the embedded or discrete AES audio inputs as the
voiceover audio source for the AES and embedded audio outputs. (See section 3.11.1). The voiceover
audio is mixed with the program audio at the mix levels specified in the HTML Audio Setup page (see
section 3.11.1) when the VOICE OVER button is pressed. The voiceover audio sources are also used
as the audio inputs for Emergency Alerts when the EAS option is fitted.
2.6.1. Connecting Program Audio
If you are using discrete AES program audio, connect up to 4 channels of AES audio that is associated
with the program video input (connected to the INPUT BNC) to the AES IN PROG audio inputs. If you
are using embedded program audio then you do not need to connect any program audio to the AES
