Changing The Group Setting; (For Operation With 2 Receiving Modules); Setting The Squelch; Operating The Bluetooth Receiver - Monacor TXA-1022CD Bedienungsanleitung

1) The receiving units A and B of the mod-
ule provide a control (2), CH.A and CH.B
respectively, to adjust the volume and
to switch them on and off. To switch a
receiving unit on, advance the corre-
sponding control from the position
"OFF". The left half of the display (1)
applies to receiving unit A, the right half
applies to receiving unit B. When a
receiving unit has been switched on, the
corresponding half of the display will
indicate the transmission channel. To
indicate the radio frequency, press an
arrow button ( for unit A,
The previous indication will reappear
after 2 seconds.
2) Use the buttons (3) of the module to
set the transmission channels, either
manually or by means of an automatic
scan. Leave the corresponding transmit-
ters switched off for the time being.
Channel scan:
Keep the buttons and
ously pressed for approx. 1 second until
appears on the display. The scan
will start: The receiving units will be set
to free channels without mutual interfer-
ence. If no free channels are found, the
channels set will be kept.
Manual channel selection:
If both receiving units A and B are
switched on:
1. Keep the button SET pressed until the
channel indication for receiving unit A
starts flashing on the display.
2. Select the channel for receiving unit A
with the button or
firm with the button SET.
3. The channel indication for receiving
unit B starts flashing on the display.
Select the channel for receiving unit B
with the button or
firm with the button SET.
If only one receiving unit A or B is
switched on:
Keep the button SET pressed until the
channel indication starts flashing on the
display. Select the channel with the but-
ton or and then confirm with the
button SET.
If a channel is not confirmed within
10 seconds with the button SET, the set-
ting mode will be exited and the channel
previously set will be kept.
Note: The receiving units cannot be set to the
same channel.
If, with the transmitter switched off, the
respective segment bar A or B on the
display indicates reception, interference
signals or signals from other transmit-
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 dis-
play 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.
for unit B).
– 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
simultane-
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
2) Use the button
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
and then con-
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-
and then con-
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
via channel scan,
(with the number flashing).
or to switch to .
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: (for Squelch") and the
current value (flashing) will appear on
the display.
3) Use the button or to set the value
(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
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 (16) pressed for
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
will restart flashing, and the "pairing"
process must be performed again.
6) To switch off the Bluetooth receiver,
briefly press the button . The button will
not be illuminated anymore.
