The signal generated in each of the three channels (2 microphone and 1 micro/line) pass to the
mixer circuit and then, after passing through a limiter, are sent to the A/D converter on one
hand, and to the foldback circuit on the other.
The foldback circuits allow the continuous adjustment from only Program go to Return signal,
i.e. any mix between both.
The channel levels are adjusted by the Mic1, Mic2 and Mic/Lin potentiometer.
The signal, once it has been limited, passes to the analogue-digital converter and is processed
in the DSP, that is programmed for transmission by ISDN or CTN (Commuted Telephone
Network).
In the former case, the signals reach the TA (terminal adapter) which is controlled by the
communication controller, this accepts user instructions entered through the keyboard with this
information being shown on the alphanumeric display.
In the latter case, the signals are sent to the CTN telephone socket through the D/A converter
and analog hybrid instead of the ISDN adapters (TA).
In both cases, a return signal travels in the reverse direction from the communication interface
to the DSP, from where it passes to the D/A converter that generates the Program return signal.
This signal may be heard in the commentator’s headphones.
The Unit in turn has a data and control port, to send and receive auxiliary data and for
equipment configuration and upgrading.

2. POWER SUPPLY
2.1. General
The power supply connector (1) is found on the rear panel of the unit.
2.1.1. Unit power supply
The AEQ TLE-02D can be powered by standard batteries or an external source.
If an external power supply is to be used it must be connected to the 12V DC-INPUT (1).
The power supply unit supplied with the equipment, or an alternative unit capable of delivering
the correct voltage and current, must be used.
The cable supplied with the power supply unit is fitted with a standard pin plug, which is
lockable to prevent accidental disconnection.
If a standard alkaline battery power supply is to be used:
8 standard 1.5V AA (LR6) alkaline batteries must be fitted to the AEQ TLE-02D, this will allow
approximately 1h30m autonomy at 100% yield. AEQ recommends DURACELL batteries.
2.1.2. Switching on
Before connecting the power supply ensure the on/off switch is in the OFF position.
Once the lockable plug is correctly connected to the unit, it should be connected to the network
supply.
Turn the power supply switch to ON. If all the previous steps have been correctly followed, the
display will illuminate, indicating that the equipment is receiving power.

3.2. Description of the rear panel
A series of combo XLR3-Jacks (1 and 2) are found on the front panel, one is connected to each
channel of each input. This type of connector allows the connection of male XLR3 or ¼” male
telephone type jack plugs, therefore admitting balanced or asymmetric signals.
The headphone outputs (4) are provided with ¼” stereo telephone jacks.
The Mic/Tape channel possesses a micro/line level selector switch (3).
The numbered elements and their use are described in the following selection

Microphone Inputs 1 and 2
The microphones are normally supplied with the appropriate connectors for direct connection to
the Audiocodec. The connector wiring is shown below:
XLR connectors ¼” Jack connectors
1: ground sleeve: ground
2: microphone V+ tip: microphone V+
3: microphone V- ring: microphone V-
Mic/Line Input
A cable with either a male XLR3 or ¼” stereo Jack must be used. The connector wiring is the
same as that for the microphone inputs.
Mic/Line switch
To select microphone input level, the switch is set to the rest position (switch button out), and to
select line input level, the switch is set to the activated position (switch button in).

Heaphones Outputs
A standard TRS ¼” headphone output jack is fitted. The connector wiring is shown below:
¼” Jack connectors
Tip: Left earpiece
Ring: Right earpiece
Sleeve: Common ground
Connections for Control and Data port (RS232 port)
The unit has a female DB 9 chassis mounted connector for configuration and transmission of
auxiliary data in conjunction with an external computer communicating through RS 232 protocol
(a cable fitted with male connector must therefore be used). The active contacts are:
TX 2
RX 3
GND 5
A Pin-to-Pin Male-Female cable must be used and connected to the PC serial port.
For details of the PC serial communication port, consult the user manual supplied with the
computer.
RJ45 chassis connector wiring
The RJ 45 connector connects the terminal adapter, which is included in the
equipment, with the ISDN access point (Network terminal). This connector wiring
is standard according to the following diagram.
For connection to the ISDN line socket the cable supplied with the equipment, or
similar, must be used.

RJ11 chassis connector wiring:
Connection to the telephone line is by 4 contact RJ11 type connector. The telephone line must
be connected according to the standard for RJ11 connectors (using the two centre contacts, 2
and 3).
For connection to the telephone line socket the cable supplied with the equipment, or similar,
must be used.

Selector Switch for ISDN-Analogue Telephone Line Mode (MODE SELECT ISDN/ANALOG
TELEPHONE LINE):
This selects the required line type (ISDN - CTN).
Important: To change the line type selection the equipment must be switched-off and restarted
with the new configuration.
.
Dial mode selector switch Pulse – DTMF Tones in CTN mode:
This switch selects the dial mode by Pulse or by DTMF Tones, allowing generating DTMF tones
to effect remote control operations in mode CTN.
4 Wire Interface
Full Bandwidth (20Hz-20KHz). Whether the unit is used as an Audiocodec on ISDN or as a
portable Telephone Hybrid on CTN, the transformed balanced 4W input/output is always
available, being operative to use it simultaneously with any of the two modes.
The return input has a level adjustment (TRIM) and it is permanently routed to the headset
outputs. Therefore it can be used for the connection of other Auxiliary signals that could be
required to be monitored by the reporters, such as Guides, Cue, P.A., International Sound, etc.
The Aux. out has also a mix control for the send and return signals (SOURCE), in this way
increasing the possibilities of the equipment which can be used as per the following examples:
- As a conventional 4W circuit, or a pre-mixer, setting the associated control knob
SOURCE in TX position.
- As a recording output, setting the associated control knob SOURCE in an intermediate
position TX/RX. This way, both program and return signals are available at the Output.
- As an auxiliary output of the digital hybrid, setting the associated control knob
SOURCE in RX positions. This way the unit can be connected to other equipment or to
a loudspeaker in order to use the hybrid as a hands-free telephone.
4 Wire Interface Auxiliary Input level adjustment:
The 4 wire interface auxiliary input level can be adjusted with the Trimmer (LEVEL TRIM)
located next to the interface.
Power supply:
Power is delivered to the Unit by the supplied AC-Adaptor or another suitable power supply,
through the DC-INPUT connector.
DC Voltage 12 V.
Polarity: V+ : centre pin; V- : exterior
Current: 0.52 A. @ 12V
Connector: Standard cylindrical DC, 2 mm internal, 6 mm external
Power consumption: Approx. 6W.
If the unit is to be powered by batteries, 8 standard 1.5V AA (LR6) alkaline batteries must be
fitted. The batteries are inserted through the top of the unit. AEQ recommends DURACELL
batteries. Correct polarity must be observed. Batteries must be inserted as indicated in the
diagram in the battery compartment.
