1. DESCRIPTION
1.1. The AAP1221C01
The AAP1221C01 is a monophonic analog audio preselector for twelve inputs to one
output.
Selection of the input that will be connected to the output is done remotely, either from
a PC or using a control keypad for the Albalá Ingenieros line of terminal equipment.
Multiple AAPXX2X and AVPXX2X family preselector modules can be configured to switch
simultaneously when installed in the same mounting frame. This functionality is
especially useful when working with multichannel audio or with material that contains
both audio and video.
It is possible to monitor the AAP1221C01 status remotely using a communications
controller module installed in the same mounting frame. In addition, certain controller
modules provide SNMP management and the ability to record events in a file including
date and time information for further analysis.
The AAP1221C01 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 AAPXX2X series is a family of analog audio preselectors, with the following
variations:
• AAP0621C01: An stereophonic analog audio preselector for six inputs to one output.
• AAP0622C01: An stereophonic analog audio preselector for six inputs to two outputs.
• AAP1221C01: An monophonic analog audio preselector for twelve inputs to one
output.
• AAP1222C01: An monophonic analog audio preselector for twelve inputs to two
outputs.

3. INSTALLATION
THE AAP1221C01 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 AAP1221C01 module is composed of two parts: one AAP1221P01 main board and
one XAP122XP03 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 AAP1221P01 main board and one XAP122XP03 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.
11
Albalá Ingenieros | Manual AAP1221C01
• The AAP1221C01 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 AAP1221C01 modules as
will fit in them.
3.5. Installing the module in the mounting frame
The steps needed to install the AAP1221C01 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 AAP1221C01 in the mounting frame.
3 - Install the XAP122XP03 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 AAP1221P01 board (main board of the AAP1221C01 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 AAP1221C01 module rear board connector layout.
Rear view of the AAP1221C01
The AAP1221C01 module has twelve inputs (IN1 to IN12) and one monophonic analog
audio output distributed to two connectors (OUT1, OUT2).
The balanced outputs of the distributor have been designed with two independent
amplifiers with gains of +1 and -1, respectively. When used as two monophonic,
unbalanced outputs the number of output per channel is doubled, however the
maximum signal level cannot exceed 18dBm for a load of 600Ω. It should be noted that
the output marked with the negative (-) sign will be reversed by 180o in phase with
respect to the output with the positive (+) sign.
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.
14
Albalá Ingenieros | Manual AAP1221C01
3.6.1. Analog audio connections
Analog audio inputs are high impedance, balanced and use 3.81mm 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.
The analog audio outputs are balanced, use 3.81mm pitch terminal block connectors
and their characteristic impedance is 73Ω.
For analog audio connections two-wire shielded cable is preferred. The GND terminal
allows connection of the cable shield.

4.2. Functional description
Selection of the input for connection to the output is done remotely, either by a PC or
with a control keypad. The following section will explain the various ways to connect the
preselector to PC or control keypad.
The AAP1221C01 has two functional modes, depending upon how it will be used.
When only one preselector module is being used then the AAP1221C01 operates in
Master Mode. In Master Mode the AAP1221C01 only responds to commands received
from the internal communications bus of the mounting frame directed to the slot where
the preselector is installed.
In systems that use multiple preselectors that must all switch at the same time, either
because there are multiple audio channels being processed or because the switching
must synchronize to a video preselector the module can be operated in Slave Mode, in
which it responds to commands sent to a module in Master Mode installed in a different
slot. In Slave Mode the module continues to respond to commands sent to the slot
where it is installed.

4.3. Module remote control and supervision
The AAP1221C01 requires remote control for configuration.
In order to perform remote configuration and supervision of the module an optional
TL3000 family remote communications controller must be installed in the mounting
frame.
The main function of the communications control module is to interface between a
10/100 Ethernet port, an EIA-RS232 or an EIA-RS485 serial port and the internal bus of
the mounting frame. The following illustration shows the most common control
situations: from a computer or control panel via Ethernet, from a computer via an
EIA-RS232 serial port and from a control panel via an EIA-RS485 serial port.
Certain communications control modules provide additional, more advanced functions
such as an SNMP agent, logging of status changes of the modules and a Web interface
for remote control, etc.
Software for simple configuration and supervision with a GUI for multiple modules can
be downloaded from the Albalá Ingenieros website.

The following functions of the AAP1221C01 can be performed remotely:
- Selection of the functional mode.
- Selection of the input to be connected to the output.
4.3.1. Details of the AAP1221C01 registers
The AAP1221C01 module provides control and status registers that can be read and
written by means of specific commands described in the communication control
module user manuals.
The parameter information grouped in the CONTROL or RAM sections is stored in
volatile memory. Any modifications to the parameters will be lost when the module
power supply is disconnected unless the "EEPROM Save" button within the software
has been pressed.
The STATUS section parameters are read-only and cannot be modified.
The EEPROM section parameters are rarely used and are stored directly in non-volatile
memory.
The parameters that can be controlled and supervised remotely for each version of
the firmware are listed below:
