1 AMX-101i Analog Audio Multiplexer
1.1 Introduction
The AMX-101i is a high-quality, high-performance analog audio
multiplexer/embedder designed to insert two 20-bit sampled analog audio stereo
signals into a single SMPTE 259M-C serial digital video signal. The AMX-101i
has an on-board audio test tone signal and automatic 525/625 input detection
with full EDH monitoring.
The AMX-101i is a member of the imaging family of digital video modules and
therefore requires the imaging Quartet-A-75 or the imaging Symphonie frame with
Symphonie-R-A75 rear module for mounting and power.

2.2 AMX-101i Mechanical Installation
Due to its audio inputs, the AMX-101i must be mounted within Quartet-A-75 or or
Symphonie imaging frames using Symphonie-R-A75 or Symphonie-R-A110 rear
modules. This section describes how to install the AMX-101i in any of these
frames. It is not necessary to switch off the power from these frames when
installing or removing the AMX-101i.
2.2.1 Quartet-A-75 Frame
To install this module into the audio Quartet frames follow these steps. For a
closer look at module installation and removal, refer to the frame's Guide to
Installation and Operation.
1. Remove the frame's front panel by rotating the thumb screws counterclockwise. Pull on the handles.
2. Select an empty slot.
3. Carefully place the AMX-101i between a set of module guides and gently
push the module towards the rear of the frame until the module's edge
connector is secured to the backplane. Pull lightly on the module verifying
that it does not move.
4. Replace the frame's front panel. Make sure to rotate the thumb screws
clockwise in order to secure it to the chassis.
2.2.2 Symphonie Frame
To install this module into the Symphonie housing frame, follow these steps. To
function, the AMX-101i requires the Symphonie-R-A75 or –R-A110 rear module.
For a closer look at module installation and removal, refer to the frame's Guide to
Installation and Operation.
1. Remove the front panel door by pulling on the door handles and gently
lowering it.
2. Select an empty slot.
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. Replace the front panel door.

2.3 Rear Panel Label
A connector label has been shipped with the AMX-101i. This label is to be
installed on the frames’ rear panel in order to identify the module's external
connectors.
2.3.1 Quartet-A-75 Frame
To install the rear panel label on a Quartet-A-75 frame, follow these steps while
referring to Figure 2.1.
1. Remove the screws associated with the AMX-101i connectors.
2. Carefully apply the label to the connectors.
3. Replace the screws making sure not to damage the label.
