3 Applications and Accessories
GB
In combination with a receiver tuned to the same radio
frequencies, this PLL multifrequency transmitter allows
to set up a wireless mono audio transmission system.
The signal of the transmitter can be sent to any de sired
number of receivers. Thus, the system is ideally suited
for applications where the signal of an audio source is
fed to several people, e. g. guided tours or multilingual
lectures. For radio transmission, 16 channels in the
UHF range from 863.1 MHz to 864.9 MHz are available.
The transmitter can be combined with the following
MONACOR receivers:
Unit Type
TXA-800 battery-operated active speaker
system with receiving part
TXA-800CD battery-operated active speaker
system with CD player and
receiv ing part
TXA-802CD battery-operated active speaker
system with CD player, transmit-
ting part, and two receiving parts
TXA-800R pocket receiver
ATS-16R pocket receiver
The transmitter has two microphone inputs (balanced
and unbalanced, with +5 V T-power to be activated)
and an input for a unit with line output level (e. g. CD
player) to be monitored via headphones. A line output
allows connection of an amplifier or a sound recorder.
Installation material is provided for installing two
TXA-800ST transmitters into a rack. The second trans-
mitter can be supplied with power via the DC voltage
output of the first one.

3.1 Conformity and approval

Herewith, MONACOR INTERNATIONAL declare that
the transmitter TXA-800ST is in accordance with the
basic requirements and the other relevant regulations
of the directive 1995/5/EC. The declaration of conform -
ity can be found in the Internet via the MONACOR
INTERNATIONAL home page (www.monacor.com).
The transmitter is generally approved for operation
in EU and EFTA countries; it is licence-free and re -
quires no registration.

4 Rack Installation

Two TXA-800ST transmitters can be installed into a
rack for units of a width of 482 mm (19") via the instal-
lation material provided. In the rack, 1 RS (rack space
= 44.5 mm) is required.
Connect the transmitters by means of the two
adapt ers on the upper and lower sides, then fasten the
two brackets with four screws each to the left and right
sides of the transmitter pair and install the transmitter
pair into the rack via the brackets (→ see figure 3).

5 Connection
1) Screw the antenna provided onto the TNC jack
ANTENNA (14) and put it in a vertical position.
2) The transmitter has two microphone inputs MIC IN
for connecting a microphone:
When the microphone is balanced, use the XLR
jack (17).
When the microphone is unbalanced, use the 6.3 mm
jack (19); in case of a 3.5 mm plug on the micro-
phone, insert a corresponding adapter.
In case of an electret microphone requiring a 5 V
operating voltage, switch on the +5 V T-power for
the 6.3 mm jack: set the switch (18) next to the
Order No.
jack to ON.
17.2220
Caution
G
Do not activate the T-power when a dynamic
17.2230
microphone is connected to the 6.3 mm jack,
otherwise it may be damaged!
G
Only activate/deactivate the T-power when the
17.2240
transmitter is switched off, otherwise this will
cause loud switching noise.
3) The stereo input LINE IN (16) allows to connect an
17.2590
audio unit with line output (e. g. CD player, cas-
sette recorder, radio).
24.4680
To monitor the input signal of the jacks LINE IN
[unaffected by the volume control AUX (4) and by
the position of the button TX (5)], connect head-
phones to the 6.3 mm jack
4) The output LINE OUT (15) will get the same signal
as the transmitting part [i. e. the signal of the audio
source selected with the button TX, (3) or (5), or the
mixed signal of the audio sources when both but-
tons TX are pressed]. A mono signal is available at
both phono jacks, e. g. for connection of the line
input of an amplifier or sound recorder.
5) For power supply, connect the power supply unit
provided to the jack POWER IN (21) and to a mains
socket (230 V~/50 Hz).
If a second transmitter TXA-800ST is used, it
can be supplied with power via the first transmitter:
connect the jack POWER OUT (20) of the first
transmitter via a cable with low voltage plugs (plug
dimensions → chapter 7) to the jack POWER IN
(21) of the second transmitter.
6 Operation
Prior to switching on, turn the volume controls MIC (2)
and AUX (4) counter-clockwise to the left stop.
1) To switch on the unit, press the POWER switch (1):
The switch will light up.
2) Adjust the transmission channel on the correspond -
ing receiver (→ see operating instructions of the
receiver).
3) Turn the control (11) of the transmitting part clock-
wise until it is switched on: The transmission LED
TX (7) will light up and the display (6) will indicate
the channel currently adjusted.
