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 counter-
clockwise. 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.

2.3.2 Symphonie Frame
To install the Symphonie label, follow these steps while referring to Figure 2.2.
1. On Symphonie’s rear panel, locate the appropriate connectors.
2. Remove the rear label mounting screws from the rear module.
3. Carefully apply the label to the connectors making sure the label’s text is read
from top to bottom. Make sure to apply the label to the Symphonie-A75 rear
module.
4. Replace the screws making sure not to damage the label.

2.4 AMX-101i Electrical Installation
Refer to Figure 2.5 for rear panel electrical installation.
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 AMX-101i 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, Input Status Monitoring
for a description of error and EDH status on the input signal.
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.
AUDIO IN: analog audio input
Connect 2 stereo or 4 monaural balanced analog audio signals to the AUDIO IN
connector. Figure 2.3 provides the pinout of the HD-15 rear panel connector.

4:2:2 OUT 1, 2, and 3: serial digital video outputs
Serial digital video with inserted audio is provided by the 4:2:2 OUT 1, 2, 3
connectors. All outputs conform to the SMPTE 259M-C standard.

2.5 600 ΩInternal Termination Jumper
When 600 Ωaudio impedance equipment is connected to the AMX-101I, its input
impedance must be internally calibrated for 600 Ω. To do so, perform these
steps. It is necessary to use the imaging Extender Module to access the
potentiometers (refer to the frame’s Guide to Installation and Operation for more
information).
1. Referring to Figure 2.5 next page, install a jumper on the appropriate
connector LK1 through LK4. LK1, LK2, LK3, and LK4 correspond to inputs
R1, L1, R2, and L2 respectively.
2. Install the analog audio input.
3. Turn on the AMX-101i.
4. Using a technician's screwdriver, slowly tune the corresponding
potentiometer until the PEAK LED turns on. PEAK 1 LED is used to adjust L1
or R1 and PEAK 2 for L2 or R2.
5. Now, carefully reverse the tuning direction of the potentiometer stopping as
soon as the corresponding PEAK LED turns off.
6. Remove the jumper.
7. If you wish to calibrate all four inputs, repeat steps 1 to 6.
