1 ADX-102i/104i/108i AES/EBU Demultiplexer
1.1 Introduction
The ADX-102i/104i/108i is a very high-quality AES/EBU demultiplexer series. They
are designed to extract up to eight 24-bit digital audio signal pairs from a single
SMPTE 259M serial component digital video signal. The LTC output comes from
the sampled LTC. A delay of up to 6 fields can be added to the audio and the time
code to compensate for external system timing delays. The ADX-102i/104i/ 108i
series has a built-in audio test generator as well as automatic 525/625 input
detection. In addition, these modules supports full EDH monitoring.
Audio groups are normally embedded into the HANC area of the 4:2:2 signal per
SMPTE 272M. Miranda has expanded on this capability by permitting embedders
to be cascaded and to also embed audio groups into time slots in the active picture
area.
The ADX-102i/104i/108i are members of the imaging family of digital video
modules and therefore require the imaging Quartet-A-75, Quartet-A-110 or the
imaging Symphonie frame with Symphonie-R-CX, Symphonie-R-A75, Symphonie-
R-A110 or Symphonie-R-AX rear modules, for mounting and power.
1.2 Features
•Serial digital 4:2:2 input with active loop-through
•Up to 8 AES/EBU outputs per module
•Up to 48 cascaded AES/EBU outputs
•Dolby E compatible
•Up to 24-bit digital audio
•LTC output
•Left/Right channel swapping
•Audio group selection
•Audio output muting
•Audio and TC selectable delay

4:2:2 IN: serial digital video input with active loop-through
Connect a 4:2:2 serial digital video source to 4:2:2 IN. The ADX-102i/104i/108i
accepts a 4:2:2 serial digital video signal in either 525 or 625-line format. This
input must conform to the SMPTE 259M-C standard. Make sure the input 4:2:2
cable has a maximum length of 250 m (850'). Refer to section 3.3, Status
Monitoring for a description of error and EDH status on the input signal. The 4:2:2
serial digital loop-through signals are provided by the BNC connector labeled 4:2:2
LOOP. This is an active loop through and does not require termination when not in
use.
Make sure that all serial digital video connections are point-to-point. For instance,
there must be a point-to-point connection between the 4:2:2 IN BNC and the
source equipment. If a T-connector is used to connect other equipment, the
maximum specified cable length is no longer valid.
AES OUT 1 to 4: digital audio outputs (Symphonie-R-CX, Symphonie-R-A75,
or Quartet-A-75 rear panels)
The AES OUT BNC connectors provide unbalanced digital audio signals extracted
from the selected audio group of the 4:2:2 digital video source. These output
signals conform to the AES-3id standard for 75Ωimpedance signals. Set jumpers
on card for 75Ω as described in section 2.5 Impedance Selection Jumpers.
AES OUT: digital audio outputs (Symphonie-R-A110, Symphonie-R-AX and
Quartet-A-110 rear panels)
The AES signals, output on the AES OUT HD-26 connector, provide 110Ω
balanced digital audio signals conforming to the AES3 standard. There are eight
AES signals available. Figure 2.4 provides the pinout of the HD-26 rear panel
connector. Set jumpers on card for 110Ω as described in section 2.5 Impedance
Selection Jumpers.
Figure 2.4 AES connector pinout (HD-26)
LTC OUT: linear time code output
When present, the time code signal is extracted and output on the LTC OUT BNC
connector or the HD-15 connector. When output as a balanced signal on the

6
HD-15 connector (Figure 2.5) the signal may be used as 2 unbalanced signals or
one side may be grounded. This signal conforms with the SMPTE 12M standard.
Figure 2.5 LTC connector pinout (HD-15)
4:2:2 LOOP : serial digital video output
An active loop-through of the serial digital video signal is provided by the 4:2:2
LOOP connector(s). A single 4:2:2 output is provided when used with Quartet-A-
75, Quartet-A-110, Symphonie R-A75 or Symphonie R-A110. Symphonie-R-CX or
Symphonie-R-AX provide two 4:2:2 outputs. All outputs conform to the SMPTE
259M-C standard.
