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maximum specified cable length is no longer valid.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 75Ω impedance 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

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.

Figure 2.6 ADX-102i/104i/108i electrical installation

2.5 Impedance Selection Jumpers

Depending on the type of rear module used with the ADX-102i/104i/108i, the

proper output impedance selection must be set on the module. When used with an

AES3 rear panel (Symphonie-R-AX, Symphonie-R-A110 or Quartet-R-A-110) set

the impedance jumper to 110Ω. When used with an AES-3id rear panel

(Symphonie R-A75, Symphonie-R-CX or Quartet-A-75) set the impedance jumper

to 75Ω.

3.2 Menu Introduction

Most ADX-102i/104i/108i parameters are accessed and changed via an easy-to-

use menu. The flow chart of Figure 3.2, 3.3 and 3.4 outlines the entire ADX-

102i/104i/108i menu path. The menu consists of 7 major functions:

• Embedded audio group selection

• Audio channel swap and/or mute

• Audio and LTC delay selection

• AES channel status information

• Slot selection for cascade operation

• Test signal setup

• Factory reset

Each menu is described throughout this section. The following items should be

remembered when accessing the menu.

Normal Mode

When the menu is not being accessed we refer to this as normal mode. When in

normal mode, the display is turned off.

Automatic Exit From Menu After 1-Minute Interval

If the menu is currently being accessed and no push-button has been pressed for 1

minute, the ADX-102i/104i/108i automatically exits from the menu thereby returning

to normal mode. Also, changes made to the current parameter will be stored.

Navigating Through the Menu

The front panel push-buttons are used to navigate the menu of Figure 3.2. The

following describes the function of each push-button when navigating through the

menu.

(

+): Press (+) to move down in the menu or to increase the parameter

value. For example, if you are currently at A1-2 in the OUT menu,

pressing (+) will scroll downwards through the selections A3-4, A5-6

and A7-8. Depressing (+) during an adjustment will increase the

parameter value or scroll at a faster rate.

(

): Press (-) to move up in the menu or to decrease the parameter value.

For example, if you are currently at A7-8 in the OUT menu, pressing (-

) will scroll upwards through the selections A5-6, A3-4 and A1-2.

Depressing (-) during an adjustment will decrease the parameter value

at a faster rate.

SELECT: Changes to a menu parameter are stored immediately to non-volatile

memory. For example, after the desired A1-2 audio source has been

set, press SELECT. The menu returns to OUT and the new audio

source is stored for the AES1 and AES2 signal pair (A1-2).

ESC: If ESC is pressed after making changes to a parameter, the parameter

is reset to the value it had prior to the change. For example, after

changing the A1-2 audio source, press ESC. The menu is returned to

A1-2 and the previous audio source setting is reloaded.
