Operating The Receiving Module; Changing The Group Setting (For Operation With 2 Receiving Modules); Setting The Squelch - Monacor TXA-1020 Manual De Instrucciones

Volume adjustment of the audio sources:
– for the two receiving units of the
2-channel receiving module (opera-
tion chapter 7.1), use the corre-
sponding volume control (2), CH.A
or CH.B
– for model TXA-1020USB:
for the integrated audio player (oper -
ation chapter 1.1), use the volume
buttons at the player or on the remote
control
– for a unit connected to the input AUX
IN (15) and the Bluetooth receiver
(operation chapter 7.2), use the
volume control (8) of the operating
panel AUX
Note: The control will determine the vol-
ume of the mixed signal of both sources
when they are used at the same time.
– for a unit connected to the input LINE
IN (13), use the volume control (7) of
the operating panel LINE
– for a microphone connected, use the
volume control (10 or 9) above the
corresponding input
CAUTION Never adjust the active
speaker system to a very
high volume. Permanent
high volumes may damage
your hearing! Your ear will
get accustomed to high
volumes which do not
seem to be that high any
more after some time.
Therefore, do not further
increase a high volume
after getting used to it.
4) Use the high frequency control TREBLE
and the low frequency control BASS (6)
to adjust the tone of the active speaker
system.
5) Use the button VOICE PRIORITY (12)
to activate the microphone priority func-
tion. When the button is pressed (LED
beneath the button illuminated), the vol-
ume of the music currently played will be
substantially reduced while announce-
ments via a microphone connected or a
wireless microphone are being made.
To deactivate the function, disengage
the button again.
Note: The function will also have an effect on
the output signal of the jacks LINE OUT and
AUX OUT (14).
7.1 Operating the
receiving module
Using the 2-channel receiving module and
two appropriate transmitters (e. g. pocket
transmitter TXA-800HSE, wireless micro-
phone TXA-800HT), two transmission
paths can be established.
1) The receiving units A and B of the
module provide a control (2), CH.A and
CH.B respectively, to adjust the volume
and to switch them on and off. To switch
a re ceiving unit on, advance the cor re-
sponding control from the position "OFF".
12
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 correspon-
ding half of the display will indicate the
transmission channel. To indicate the
radio frequency, press an arrow button
( for unit A, for unit B). 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
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
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-
and then con-
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

setting mode and to activate the squelch
