1 General
1.1 Introduction
Module of the imaging range, ADA-702i is a dual 1 to 5 analogue distribution amplifier. It
distributes a stereo audio signal in any digital environment where an analogue signal has to be
distributed before digital conversion or after analogue re-conversion. ADA-702i offers moreover
distribution of time code signals.
ADA-702i may operate in single mode 1 input to 10 outputs, by internal configuration.
ADA-702i includes 0.5 dB steps level adjustment for each input within a range –20 dB to +20 dB.
Level adjustments can be remote controlled.
It transmits status signal information such as signal absence or signal overload (open drain) to
the remote control supervision system (ICP-S) or a GPI.
1.2 Features
• Input signal presence detection
• Input or Output overload signal detection
• Amplitude adjustment from the front user interface or from external VCA
• Signal alarm delay adjustment by coding wheel on the front user interface
• Fully compatible with the Symphonie and Quartet housing units

2 Installation
2.1 Unpacking
Make sure the following have been shipped with your ADA-702i. If any of the following items are
missing, contact your distributor or Miranda Europe
• ADA-702i
• ADA-702i rear panel labels
2.2 Mechanical installation
The ADA-702i must be mounted within Quartet-A-75 or Quartet-M tray in order to provide power
to the card.
This section describes how to install the ADA-702i in any of these trays. It is not necessary to
switch off the power from these trays when installing the ADA-702i.
2.2.1 imaging Quartet series trays
To install this card into Quartet-A-75 or Quartet-M follow these steps. For a closer look at card
installation and removal, refer to the tray's technical manual.
1. Remove the tray's front panel by rotating the thumbscrews counter clockwise. Pull
on the handles.
2. Select an empty slot
3. Carefully place the ADA-702i between a set of card guides and gently push the
card towards the rear of the tray until the card edge connector is secured to the
backplane. The card's edge connector having 96 points, it may be necessary to
push lightly when connecting the two connectors. Pull lightly on the card verifying
that it does not move.
4. Replace the tray's front panel. Make sure to rotate the thumbscrews clockwise in
order to secure it to the chassis.

2.2.2 imaging Symphonie Housing Frame
It is not necessary to switch off the power when installing or removing a module from/to
Symphonie. To install a module, follow these steps. For a closer look at card installation and
removal, refer to the housing frame's Guide to Installation and Operation.
Rear Module Installation
Before installing, check the rear panel corresponds to the card to install. If no rear module is
present, follow the procedure below to install it.
In order to maintain the inter-rear module spacing, make sure to remove and replace one rear
module at a time. That is, at all times, there must be at least 15 rear modules installed. To
install a module, follow these steps.
1. Locate an empty compartment.
2. Select an empty compartment. Make sure that the rear panel corresponds to the
card to install,
3. Carefully place the rear
module between the rear
module guides (refer to
Figure 2.4) and slowly push
the module towards the front
until it rests against the rear
panel. It may require a light
pressure to compress the
EMI gaskets on both sides.
4. Using a flat edge
screwdriver, secure the top
and bottom screws to the
frame.
Figure 1: rear panels for Symphonie
Board installation
1. Open the front panel door by pulling on the door handles and gently lowering it.
2. Unscrew the bar.
3. Carefully place the module between the module guides and slowly push the module
towards the rear of the frame until the module's edge connector is secured to its rear
module. A light pressure to mate the connectors may be required. Pull lightly on the
module verifying that it does not move.
4. To install the Symphonie-R-M or Symphonie-R-A-75 rear module, refer to the housing
frame's Guide to Operation and Installation.
5. Replace the front panel door.

2.3 Electrical installation
When connecting the ADA-702i to external equipment, make sure that all connections are point-
to-point. Also, make sure that the cable lengths of the input and output serial digital cables are
maximum 250 m each.
Refer to figure 1 and to the following descriptions for a complete ADA-702i installation.
This equipment is conform to the CEE 89 / 336 directive and operation is subject to the following
two conditions:
1- this equipment may not cause harmful interference according to EN 50081-1
rules.
2- this equipment must accept any interference received according to EN 50082-1
rules.
Precaution of use:
Several components included are very static-sensitive. To avoid damaging those components,
be sure to respect the following rules:
1- before touching any component or any other element of the card, be sure to
reduce any static electricity on your person. One way to do this is to touch a surface
connected to ground, or to wear a wrist strap attached to ground.
2- when handling card, hold it by the edges avoiding touching the components.

2.4 Rear panel label
2.4.1 Quartet Frame
A connector label has been shipped with your ADA-702i. This label is to be connected on the
Quartet trays rear panel in order to identify the ADA-702i external connectors.
1. To install the label, follow these steps
2. On the tray's rear panel, locate the ADA-702i connectors
3. Remove the screws as shown in the following diagram
4. Carefully apply the label to the connectors
5. Replace the screws making sure not to damage the label.
