inputs. The HTML Audio Setup page is used to select the program audio source for each of the
Preview and Program audio outputs. (See section 3.11.1)
2.6.2. Connecting Voice Over or EAS Audio
If you are using discrete AES voiceover audio, connect up to 4 channels of AES audio to the AES IN
ALT audio inputs. If you are using embedded voiceover audio then you do not need to connect any
program audio to the AES inputs. The HTML Audio Setup page is used to select the voiceover audio
source for each of the Preview and Program audio outputs. (See section 3.11.1) This audio will be
mixed with the program audio at the mix levels specified in the HTML Audio Setup page. (See section
3.11.1)
2.6.3. Connecting the Audio Outputs
The AES PROG OUT connectors contain the audio outputs from the program audio buss and should
be connected to the main broadcast chain of your plant. The AES PROG OUT outputs are protected
by bypass relays (relays are optional on HD9625LGA). When the relays are active, the AES PROG
OUT outputs are directly connected to the four AES PROG IN inputs. The audio on the AES PROG
OUT Outputs is also embedded into groups 1 and 2 on the program video outputs.
The PREV AES OUT connectors contains the audio outputs from the preview audio buss and will
normally be connected to your audio monitoring system to allow you to hear the program audio output
before it goes on air. When the bypass relays are active, the PREV AES OUT outputs will not have
any audio on them. The audio on the AES PREV OUT outputs is also embedded into groups 1 and 2
on the preview video outputs.

CONNECTING THE LINEAR TIME CODE
The 9625LG Series Keyers have a linear time code (LTC) input used to provide time information for the
analog or digital clock logos. Connect the LTC output from your house master time code source to the
LTC IN XLR connector. When using an unbalanced input to the reader, the signal should be applied to
pin 3 of the LTC input connector. Normally, the unused input (pin 2) should be connected to ground
(pin 1).

CONNECTING TO AN ETHERNET NETWORK
The 9625LG Series Keyers are designed to be used with either 10Base-T (10 Mbps) or 100Base-TX
(100 Mbps) also known as Fast Ethernet, twisted pair Ethernet cabling systems. When connecting for
10Base-T systems, category 3, 4, or 5 UTP cable as well as EIA/TIA – 568 100Ω STP cable may be
used. When connecting for 100Base-TX systems, category 5 UTP cable is required. The cable must
be "straight-through" with a RJ-45 connector at each end. Make the network connection by plugging
one end of the cable into the RJ-45 receptacle of the 9625LG Series Keyer and the other end into a
port of the supporting hub.
The straight-through RJ-45 cable can be purchased or can be constructed using the pinout information
in Table 2-8. A color code wiring table is provided in Table 2-8 for the current RJ 45 standards (AT&T
