Conformity And Approval; Power Supply - IMG STAGELINE TXS-400SET Mode D'emploi

3.1 Conformity and Approval

Herewith, MONACOR INTERNATIONAL declare that
the units TXS-400SET, TXS-402SET, TXS-440SET
and TXS-442SET are in accordance with the basic
requirements and the other relevant regulations of
the directive 1995/5/EC. The declaration of conformity
can be found in the Internet via the MONACOR
INTERNATIONAL home page
(www.imgstageline.com).
The units are licence-free and generally approved
for operation in EU and EFTA countries.

4 Power Supply

4.1 Microphone
1) Unscrew the screw cap (11) at the lower end of the
microphone.
2) Insert a 9 V battery with the positive and negative
connections as printed in the battery compartment
(12). Screw on the cap (11).
3) With a new battery the microphone can be operated
for approx. 6 – 8 hours. If the power LED (14) does
not light up with the microphone switched on, the
battery is exhausted and must be replaced.
4) If the system is not used for a longer period (e. g. for
more than a week), the battery should be removed
to prevent damage to the microphone due to battery
leakage.
4.2 Receiver
1) Connect the supplied plug-in power supply unit to
the power supply jack SUPPLY 12 V
2) Connect the plug-in power supply unit to a mains
socket (230 V~/50 Hz).
3) The receiver can also be supplied with any other
12 V DC power source of a minimum rating of
300 mA, e. g. car battery or power supply unit. For
connection, a low voltage plug 5.0/2.1 mm (out-
side/inside diameter) is required. The positive pole
must be applied to the center contact.
5 Operation
1) The receiver is provided with two outputs for
connecting the subsequent unit (e. g. amplifier,
mixer):
BAL MIC (10) = XLR jack, balanced
for connecting a balanced microphone input
AUX (9) = 6.3 mm jack, unbalanced
for connecting an unbalanced microphone input
or a highly sensitive line input
If the subsequent unit is provided with a balanced
microphone input, the XLR jack should be used for
an optimum signal transmission.
Connect the subsequent unit. Switch on the micro-
phone system completely before switching on the
subsequent unit or advancing the corresponding
mixer control.

2) Place the antenna/s (6) in a vertical position and
extract them to their full extent. In case of models
TXS-440SET and TXS-442SET turn the two anten-
nas away from each other at an angle of approx.
45° to their former position.
3) Switch on the receiver with the POWER switch (4).
The POWER LED (1) will light up.
4) Adjust the muting threshold. For this purpose leave
the microphone switched off. Use a small screw-
driver to turn the control SQUELCH (7) clockwise to
the position "MAX SENSITIVITY". The reception
LED (2) must not light up:
TXS-400SET, TXS-402SET – "MIC ON" must not
TXS-440SET, TXS-442SET – neither "A" nor "B"
If the reception LED lights up, interferences are
received. To suppress these interferences, only turn
the control SQUELCH counter-clockwise until the
reception LED is extinguished. Do not turn the con-
trol any further otherwise the microphone signal
may also be suppressed.
5) Switch on the microphone: Set the switch (13) to
the upper position. In mid-position the microphone
is mute, i. e. no signal is transmitted. The reception
LED (2) at the receiver must light up:
TXS-400SET, TXS-402SET – "MIC ON" lights up
TXS-440SET, TXS-442SET – "A" or "B" lights up
If the LED remains dark, the reception is too poor:
a Is the microphone battery exhausted? See chap-
ter 4.1.
b Is the distance between microphone and re-
(5).
ceiver too long (max. approx. 30 m)?
c Is the reception disturbed e. g. by objects in the
transmission path?
d Can the reception be improved by turning the
antenna/s?
e Is the muting threshold adjusted via control
SQUELCH (7) too high? See item 4).
6) Switch on the subsequent unit or advance the cor-
responding control of the mixer. If the output AUX
(9) is used, adjust the output volume to the input of
the subsequent unit via the control AUX VOLUME
(8).
Important! Do not set the control AUX VOLUME to
zero (i. e. to its extreme left position) if the signal is
received at the XLR jack (10).
7) If the microphone system is overloaded because
the volume at the microphone is too high, the red
LED AF PEAK (3) will light up – independent of
volume control AUX VOLUME (8). The volume of
the sound source must be reduced or the distance
between the microphone and the sound source
must be increased.
If the volume at the microphone is low, a poor
S/N ratio is obtained. The volume of the sound
source must be increased or the distance between
the microphone and the sound source must be
reduced.
