1. DESCRIPTION
1.1. The AAD3001C01
The AAD3001C01 module is an audio amplifier-distributor from input to six outputs.
Both the input and the outputs are transformer isolated, making this device ideal for
signal distribution applications with high common mode voltages.
Each output has a level adjust that is accessible from the front panel of the module; this
range goes from -4 to +12dB. Each output also has its own amplifier circuitry, so that a
short circuit at one output will not affect the others.
The AAD3001C01 is a TL3000 terminal line module and can be housed in a three rack
unit (3 RU) UR3000 mounting frame or a 1 RU UR3100 mounting frame.
The AAD300X family contains a group of analog audio distributor modules, with the
following variants:
•AAD3001C01: An analog audio distributor from one input to six outputs with
transformer balancing for the input and each output along with independent level
controls for each output.
•AAD3002C01: A dual analog audio distributor from one input to three outputs per
channel with transformer balancing for the inputs and all outputs along with
independent level controls for each output.

1.2. Features
• Analog audio signal distributor.
• Distributes one audio input to six outputs.
• Transformer isolated inputs and outputs.
• Low noise.
•Each channel provides independent gain adjustment with a range of -4 to +12dB via
front panel potentiometers.
• Low impedance outputs can drive loads of up to 600Ω at maximum signal levels.
•One UR3000 mounting frame can house up to 12 AAD3001C01 modules. If power
supply redundancy is required and FA3000 or FA3001 modules are used then only 10
modules can be housed in the mounting frame. If PSU3300 or PSU3301 modules are
used for this purpose then up to 12 modules can be installed.
• One UR3100 mounting frame can house up to three AAD3001C01 modules.
• Low power.

3. INSTALLATION
THE AAD3001C01 MODULE CONTAINS ELECTRONIC DEVICES SENSITIVE TO
ELECTROSTATIC DISCHARGE. Always use antistatic bags clearly identified
with a high degree of shielding for storage and transportation.
The AAD3001C01 module is composed of two parts: one AAD3001P01 main board and
one XAD3001P02 rear board. Both parts must be installed in a UR3000 or UR3100
mounting frame following the instructions in the corresponding section of this chapter.
3.1. Initial inspection
Verify that the package has been properly handled during transport. After opening the
packaging, check that one AAD3001P01 main board and one XAD3001P02 rear board are
inside.
You must notify your Albalá Ingenieros distributor or dealer of any damage or defects
observed.
Follow the instructions in this manual to install this module in the mounting frame.
3.2. Safety instructions
•This equipment must be connected to a mains outlet with a protective
earth connection. Never use extension cords that do not have protective
earthing connection. The lack of an effective electrical connection between
the ground pin in the mains input connector of the equipment and the
protective earth of the electrical power distribution can cause serious harm.
•All modules of the Albalá Ingenieros TL3000 terminal line can be
hot-plugged or unplugged without suffering any damage or affecting the
processes that are currently taking place in other modules in the same
mounting frame. When a module is installed in an empty bay of a mounting
frame, it is necessary to mount the rear board that is part of that module.
Prior to installing this board, the mounting frame must be disconnected
from the power supply network. This is required because in addition to the
risk of electrocution for the person handling the device it is possible that a
high instantaneous current coming from the power supply could damage
the connectors and components of the mounting frame and/or the rear
board.

Albalá Ingenieros | Manual AAD3001C01
•The AAD3001C01 module and the mounting frame should always be
installed, maintained, operated and removed by personnel with sufficient
technical qualifications. The equipment should never be placed in damp
areas, near splashing liquid, or in explosive or corrosive atmospheres.
Neither modules nor mounting frames can be used in applications that
could endanger human life.
3.3. Environmental considerations
This symbol indicates that this equipment must be deposited at a collection
point for proper waste treatment once it has reached the end of its useful
life.
3.4. Power considerations
The UR3000 and UR3100 mounting frames can house as many AAD3001C01 modules as
will fit in them.
3.5. Installing the module in the mounting frame
The steps needed to install the AAD3001C01 module with the rear board in the
mounting frame are:
1 - Disconnect all power cords from the power supplies of the mounting frame.
2 - Remove the blank panels covering the front and rear of the empty bays chosen for
installing the AAD3001C01 in the mounting frame.
3 - Install the XAD3001P02 rear board ensuring that its 12-pin connectors are properly
aligned with the mounting frame´s mating connectors. Check that the orientation of
the board is correct by looking at the placement of the text printed on it according to
the illustration below.
4 - Attach the rear board to the mounting frame with two M3 metric screws and tighten.
5 - Insert the AAD3001P01 board (main board of the AAD3001C01 module) into the front
of the mounting frame. The edges of the card slide into two plastic guides inside the
mounting frame.
6 - Affix the main board to the mounting frame using the two screws included on the
front panel.
After these steps, the module is ready to be connected to other equipment.

3.6. Interconnection
The following figure shows the AAD3001C01 module rear board connector layout.
Rear view of the AAD3001C01
The AAD3001C01 module provides one analog audio input (IN-A) and six outputs (OUT1,
OUT2,OUT3,OUT4,OUT5,OUT6).
The rear interconnection board is not designed to withstand mechanical stress. The
wiring must be fastened properly to the frame where the mounting frame is housed to
prevent the rear board from supporting the weight of the cables.
3.6.1. Analog audio connections
Analog audio inputs are high impedance, balanced and use 3.81mm pitch terminal
block connectors. If another termination resistance is required, a resistor with the
desired termination value can be externally mounted between the + and - terminals.
14

Albalá Ingenieros | Manual AAD3001C01
The analog audio outputs are balanced, low impedance and use 3.81mm pitch
terminal block connectors.
For analog audio connections two-wire shielded cable is preferred. The GND terminal
allows connection of the cable shield.

4. OPERATION
This section describes the significance of the front panel indicators of the AAD3001C01
module and their remote control and monitoring ability.
4.1. Front panel description
The appearance of the front panel and the elements it contains are shown in the
following illustration.
Front panel of the AAD3001C01
The AAD3001C01 provides six gain adjustment trimmer potentiometers on the front
panel - one for each output.
