DB-25 Pin-Out

• 3G/HD/SD-SDI In (1 and 2, BNC-F): These inputs accept SDI video

signals for the 3G models.

Output Connectors

• Metered Analog (DB-25): This connector outputs the analog signal

that is displayed on the front panel level meters. The pin-out

information for this DB-25 is identical to that of the Analog Input

connector. See Figure 2–5 on page 14.

• 3G/HD/SD-SDI Re-Clocked Out (BNC): This connector outputs a

re-clocked copy of the SDI signal fed to the SDI input connector

selected for monitoring. When an SDI input is not selected for

monitoring in the unit,

SDI In 2 will be reclocked and connected to

this output by default.

• AES Unbalanced Out from SDI (HD-15): This connector outputs

de-embedded audio. The last SDI input and group selection

Note:

The DA model does not feature SDI capability.

Note:

The Analog Output Preference (AOutputPref) entry

within the Setup Menu determines how this connector

outputs the speaker assignment when a DM1, DM2, or

DM3 downmix selection is enabled. The default setting

is Downmix, which outputs the metered signal with

individual channel scaling (gain settings) intact as

determined by the selected downmix (DM1, DM2, or

DM3). If Discrete is selected, then all metered

channels are output from these connectors at unity gain.

See Analog Output Preference Mode on page 46 for

information on how to set this parameter.
