Transmitter Module
863 – 865 MHz
These instructions are intended for experts (installation) and for
users without any technical knowledge (operation). Please read
these instructions carefully prior to installation /operation and
keep them for later reference.
1 Applications
This transmitter module can be used for wireless transmission of
audio signals to a receiver matched to the same radio frequencies
(e. g. pocket receiver TXA­800R or receiver module of a portable am­
plifier system of the series TXA­820 or TXA­1020).
The module is especially designed for installation into an am­
plifier system of the series TXA­820 (for replacing the transmitter
module or for retrofitting) but may also be installed into other units.
1.1 Conformity and approval
Herewith, MONACOR INTERNATIONAL declare that the transmitter
module TXA­820MT complies with the directive 2014 / 53 / EU. The EU
declaration of conformity is available on the Internet:
www.monacor.com
The transmitter module is generally approved for operation in EU
and EFTA countries; it is licence-free and requires no registration.
Do not make any modifications to the printed circuit board of the
transmitter module! The modification may render the approval of
the module invalid and the guarantee will become null and void.
2 Important Notes
The module corresponds to all relevant directives of the EU and is
therefore marked with .
•
The module is suitable for indoor use only. Protect it against drip­
ping water and splash water, high air humidity and heat (admissi­
ble ambient temperature range 0 – 40 °C).
•
For cleaning the front, only use a dry, soft cloth; never use water
or chemicals.
•
No guarantee claims for the module and no liability for any result­
ing personal damage or material damage will be accepted if the

is not correctly installed or operated, or if it is not repaired in an
expert way.
If the module is to be put out of operation definitively, take
it to a local recycling plant for a disposal which is not harm­
ful to the environment.
3 Installation
The unit into which the module is to be inserted must be switched
off and disconnected from the mains!
3.1 Installation into an active speaker system
of the series TXA-82 0
1) If the module is to be used as a replacement for the transmitter
module installed in the unit TXA­822CD, screw off the transmitter
module installed and remove it from the compartment.
If the module is to be installed as a retrofit in the unit TXA­820
or TXA­820CD, screw off the cover of the insertion compartment
located directly above the mains jack.
2) Insert the module into the compartment. Make sure to correctly in­
sert the printed circuit board into the lateral guide rails of the com­
partment. Then screw the front plate of the module to the unit.
3.2 Installation into another unit
Make sure to observe the CE directives. Establish the connection via
the contacts of the printed circuit board:

ter module for the time being; first, set the appropriate receiver to
an interference­free transmission channel (
tions of the receiver). Then switch on the transmitter module with
the control and use the buttons to set it to the same channel
( ☞ table "Overview").
Please note: At the active speaker system into which the transmitter mod­
ule has been installed, the transmitter module and the receiver module
must be set to different channels; otherwise there will be feedback.
to adjust the volume of the audio signal transmitted.
Overview
Display to indicate the transmission channel (channel 01 ... channel 16)
Transmission indicator;
will light up when the transmitter module is switched on
Level indicators for the audio signal at the input of the transmitter module
yellow LED: will light up when a specific minimum level has been reached
red LED: overload indicator, should only light up briefly for signal peaks; if it
lights up continuously, reduce the volume of the respective audio source(s)
Buttons for setting the transmission channel:
1. Press the button SET: The channel indication on the display will start flashing.
2. As long as the channel indication flashes (10 seconds), the arrow buttons
can be used to select the channel.
3. Confirm the selected channel with the button SET (otherwise, the transmit-
ter module will return to the previously set channel after 10 seconds).
To briefly indicate the radio frequency during operation, keep one of the
arrow buttons pressed: The display will indicate the frequency instead of the
channel while the arrow button is pressed.
