1 ADX-1901 3G/HD/SD 8 Channel Analog Audio De- Embedder

1.1 Introduction

The ADX-1901 is an advanced, high quality 24-bit 48 KHz analog audio de-embedder designed to extract eight

analog audio signals from a 3G/HD/SD video signal. The ADX-1901 can process the 8 audio de-embedded channels

with functions including level, channel shuffling and mixing.

The loudness measurement features allows the measurement and logging of up to 8 audio programs with iControl

Loudness Monitoring software to analyze and report compliance with respect to various loudness legislation around

the world. Furthermore, a delay of up to 2.7 seconds can be programmed independently per de-embedded audio

channel to provide lip sync correction.

The ADX-1901 can de-embed Ancillary Time Code (ATC) in 3Gbps/HD, or DVITC in SD, to generate Linear Time

Code (LTC). Up to two GPIO can be generated by extracting GPI events from the Time Code user bits in transport

applications. Audio Metadata extraction from the VANC can be streamed to an external RS-422 output.

The ADX-1901 is designed for the Densité 2 frame, but will be compatible with the Densité 3 frame with the metal

extender. Multiple rear connector panels are available according to your application needs and the chassis type used.

A fiber input/output cartridge is offered as an option on some rear modules. Once the cartridge is installed, the input or

outputs are selectable through the control interface.

1.2 Features

2 Installation

2.1 Installation of Rear Connector Panels

Grass Valley Densité-series cards are each associated with a rear connector panel, which must be installed in the

Densité frame before the card can be inserted.

The ADX-1901 card is designed to fit into Grass Valley’s Densité-2 frame. Two different rear connector panels are

available for this configuration. Due to connector space requirements, a double-slot-width rear panel is necessary:

•ADX-1901-DRP Double-slot-width panel for Densité-2

•ADX-1901-DRP-F Double-slot-width panel for Densité-2 with fiber I/O

With a factory-installed adapter mounted on the ADX-1901 card, it can be installed in a Densité-3 frame. In this case,

only a single-slot-width panel is required. Two rear panels are available:

•ADX-1901-3SRP Single-slot-width panel for Densité-3

•ADX-1901-3SRP-F Single-slot-width panel for Densité-3 with fiber I/O

See section 2.4 for details of the signal connections available on each of these panel types.

All cards and rear panels can be installed with the frame power on. The card has connectors which plug into a mid-

frame mother board for distribution of power and for connection to the controller card, and a second connector which

plugs directly into the rear connector panel for input and output.

The rear connector panel must be installed with the card out of the frame.

•To remove an existing card from the slot, tilt up the swivel handle on the front of the card to lever the

connectors apart, then use the handle to pull the card straight out of the slot.

Figure 2.1 Densité-3 frame – rear panel installation

GUIDE TO INSTALLATION AND OPERATION

4| ADX-1901

To install the connector panel:

Note – the procedure is the same for both Densité-2 and Densité-3 frames.

1. If a card is installed in the slot whose rear panel is being changed, remove it as described above.

2. Remove the existing panel (either blank or belonging to an existing card that is being changed) by releasing the

captive screw(s) at the bottom.

3. Position the new panel and secure it in place with the captive screw(s) at the bottom.

2.2 ADX-1901 Card Installation

Note – The card itself (ADX-1901) is designed to fit the Densité-2 frame. If it was ordered for the Densité-3 frame

(ADX-1901-3RU), it will be delivered with an installed adapter that allows it to fit into the taller frame. The

adapter can be ordered separately and user-installed if required.

Once a matching rear connector panel is in place, install the ADX-1901 card as follows:

1. Open the front panel of the frame.

2. Slide the ADX-1901 card into the slot and push gently on the handle to seat the connectors.

When using the double-slot-width rear panel in a Densité-2 frame, the card should be inserted into the right-

most of the two slots. Inserting the card into the wrong slot will not damage the card, and will be flagged by the

on-card status LED flashing red to indicate that there is no connection to the rear panel.

3. Close the front panel of the frame.

2.3 Installation of the Optical Interface (option)

2.4.3 Details of rear panel connections

3G/HD/SD IN – Serial digital 3G/HD/SD input

Connect a serial digital video signal, conforming to the SMPTE 425M standard for 3G input signals, SMPTE 292M

standard for HD input signals or SMPTE 259M standard for SD input signals, to the connector labeled 3G/HD/SD IN.

The ADX-1901 will automatically switch to the detected line/frame rate format.

3G/HD/SD OUT – Serial digital video outputs

The ADX-1901 provides two 3G/HD/SD SDI video outputs on the connectors labeled 3G/HD/SD OUT 1 and 2. The

SDI video signal conforms to the input standard. The same signal is carried on both outputs.

ANALOG AUDIO OUT – Analog audio outputs (8)

The eight analog audio outputs are balanced outputs, via a 26-pin D-SUB female connector. Pinout for the connector

is shown in the table.

Fiber I/O – Fiber-optic inputs and outputs

Rear panels whose part number ends in –F incorporate a fiber optic interface. The interface consists of two parts:

•A socket on the rear panel into which an SFP interface module is plugged

•An SFP (Small Form-factor Pluggable) module into which the optical fibers are plugged, and which incorporates

the optical/electrical interface

The optical fibers must be terminated in an LC/PC connector.
