Setting The Squelch - Monacor TXA-1022CD Manual De Instrucciones

ters are being received. In this case,
select a different channel.
3) Switch the transmitters on and set them
to the channels of the receiving module:
Set one transmitter to the channel of
receiving unit A and set the second
transmitter to the channel of receiving
unit B.
The respective segment bars on the
display will indicate the strength of the
radio signals received. Use the controls
(2) to adjust the desired volume for each
receiving unit.
If no reception is indicated or if the re -
ception is poor, check if:
– the batteries of the transmitter are dis-
charged.
– the reception is disturbed by metal ob-
jects or other high-frequency sources.
– the distance between the transmitter
and the receiving module is too long.
– the threshold value for interference
suppression (squelch) is too high (see
chapter 7.1.2).
7.1.1 Changing the group setting
(for operation with 2 receiving modules)
The unit can be extended by another
2-channel receiving module (available as
article TXA-1020MR). To set the four trans-
mission channels via channel
change the group setting of both receiving
modules:
1) Switch off the receiving units A and B.
Then keep the button SET pressed
while switching on a receiving unit. The
display will indicate the current group
setting (with the number flashing).
2) Use the button or to switch to
3) Press the button SET to exit the group
setting mode. The squelch setting mode
will be activated; to exit the mode, press
the button SET.
Note: The setting modes will be automatically
exited after 5 seconds if no button is pressed.
Any settings made will be saved.
Perform the channel scan for the first
receiving module, switch on the appropri-
ate two transmitters and set them accord-
ingly. Leave the two transmitters switched
on so that channels already used will be
skipped during the channel scan for the
second receiving module. Then perform
the channel scan for the second receiving
module, switch on the two appropriate
transmitters and set them accordingly.

7.1.2 Setting the squelch

The squelch function will mute the respec-
tive receiving unit when the level of the
radio signal falls below the threshold value
adjusted. Thus, interference signals will not
cause noise when the transmitter is
switched off or when its radio signal is
insufficient: If the levels of the interference
signals are below the threshold value, the
receiving unit will be muted.
A high threshold value offers high inter-
ference resistance, but it will also reduce
the transmission range. Thus, when the
reception is good, a high threshold value
can be used; however, when the transmit-
ter and the receiver are far apart, a low
threshold value is recommended.
1) Switch off the receiving units A and B.
Then keep the button SET pressed
while switching on a receiving unit. The
display will indicate the group setting
( or , with the number flashing).
2) Press the button SET to exit the group
setting mode and to activate the squelch
setting mode:
current value (flashing) will appear on
the display.
3) Use the button
(level 7 = highest threshold value).
Press the button SET to exit the squelch
setting mode.
Note: The setting modes will be automatically
exited after 5 seconds if no button is pressed.
Any settings made will be saved.
7.2 Operating the
Bluetooth receiver
The Bluetooth receiver can be used to
establish a wireless connection to a Blue-
tooth audio source (e. g. smartphone,
tablet PC, MP3 player) which allows the
scan,
amplifier system to replay audio data.
Note: The Bluetooth source must be compatible
with the A2DP protocol (Advanced Audio Distri-
bution Profile); otherwise, no wireless connec-
tion will be possible.
1) To switch on the Bluetooth receiver,
keep the button
approx. 2 seconds. The button will start
.
flashing to indicate that there is no con-
nection to the Bluetooth source and that
the Bluetooth receiver is ready for "pair-
ing" (linking the Bluetooth source to the
Bluetooth receiver).
2) At the Bluetooth source, switch on the
Bluetooth function and perform the
"pairing" process (see the instructions
of the Bluetooth source, if required).
On the display of the Bluetooth source,
the Bluetooth receiver is indicated as
"TXA SERIES". The button
continuously illuminated once the link-
age has been completed.
3) At the Bluetooth source, start the replay
of audio data. The Bluetooth source can
be operated as desired (title selection,
volume adjustment, pause, etc.).
4) At the active speaker system, use the
control AUX (8) to adjust the volume.
Note: The volume control will also apply to
the unit that is connected to the AUX input
(15); therefore, do not use this input during
Bluetooth operation. Otherwise, both audio
sources will be reproduced at the same time.
5) When the Bluetooth connection is dis-
connected (e. g. when the Bluetooth
source is moved outside of the range
of the wireless connection), the button
6) To switch off the Bluetooth receiver,
