Chapter 2 System Overview

Rear Panel Connectors

If you are connecting downstream equipment to the AES loop-

through outputs of this connector, then you should unterminate this

connector. If you are not connecting downstream equipment, then

you should terminate the selected input connector. Refer to

Terminating/Unterminating Inputs on page 40 for details.

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

signals for the 3G models.

If Dolby E and Dolby D (AC-3) audio signals are encoded within an

SDI bitstream selected in Dolby Decode Mode, they will be de-

embedded and de-coded for monitoring through the unit and for

output through the Decoded Dolby E/AC-3 Out connectors. PCM

signals embedded within the SDI bitstream are also de-embedded

for monitoring through the unit. See Chapter 5: Dolby on page 49

for details.

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 2–8 on page 15.

• 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.

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 Assign 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 58 for

information on how to set this parameter.
