Operating The Receiver; Channel Scan - Monacor International TXA-802SR Mode D'emploi

5 Setting the Receiver
into Operation
1) Place the receiving antennas (5) in a vertical po-
sition .
2) To connect the receiver to the subsequent audio
unit, e . g . mixer or amplifier, use one of the two
audio outputs:
– either connect the XLR output (6) to a balanced
microphone input
– or connect the unbalanced 6 .3 mm jack (7) to
a line input; depending on the sensitivity of the
line input, set the switch (8) next to the output
to "LOW" (low output level) or "HIGH" (high
output level) .
3) For power supply, connect the power supply
unit provided to the low-voltage jack (9) and to
a mains socket (230 V / 50 Hz) .
Note: The power supply unit has a low power con-
sumption even when the receiver is switched off;
therefore, disconnect the power supply unit from the
mains socket when the receiver is not operated for a
longer period of time .

6 Operating the Receiver

To switch on the receiver, set the POWER switch (1)
to "ON" . To switch off the receiver, set the POWER
switch to "OFF" .
Each receiver unit (A and B) provides a control (2)
to switch it on and off and to adjust the volume .
To switch a receiver unit on, turn the control clock-
wise from the position "OFF" . The left half of the
display (3) applies to receiver unit A, the right half of
the display applies to receiver unit B . When a receiver
unit has been switched on, the corresponding half
of the display will indicate the transmission channel .
Note: To briefly indicate the radio frequency for a re-
ceiver unit, briefly press the button  (for unit A) or 
(for unit B) .
6.1 Establishing
wireless transmission paths
The distance between the transmitter and the re-
ceiver should be at least 2 m; the distance between
the individual transmitters should be at least 0 .5 m .
1) Set the transmission channels for the receiver
units A and B via channel scan or manually
( ☞ chapter 6 .1 .1 or 6 .1 .2) . Do not switch on
the two corresponding transmitters for the time
being . If one or more segments of a reception
indicator light up on the display, interference
signals or signals from other transmitters are
8
being received . In this case, select a different
channel for the respective receiver unit .
2) Switch on the transmitters and set them to the
channel of receiver unit A and receiver unit B
respectively . The segment bars A and B on the
display will indicate the strength of the radio sig-
nals received .
Use the controls to adjust the volume for each
receiver unit .
If no reception is indicated or if the reception is
poor, check if:
– the (rechargeable) batteries of the transmitter are
discharged
– the reception is disturbed by metal objects or other
high-frequency sources
– the distance (transmitter — receiver) is too long
– the reception can be improved by turning the
receiving antennas (5)
– the squelch value is too high (
Note concerning multichannel operation:
The number of channels to be used in parallel depends on
the conditions at the place of application (e . g . on inter-
ference due to other wireless systems or high-frequency
sources such as fluorescent lamps) . In ideal conditions,
up to four channels can be operated at the same time
without mutual interference . Two examples of a suitable
channel selection for four wireless transmission paths:
Example 1:
channel 01 – channel 03 – channel 06 – channel 12
Example 2:
channel 06 – channel 09 – channel 15 – channel 16

6.1.1 Channel scan

Keep the buttons  and  simultaneously pressed
for approx . 1 second until
display . The scan will start: The receiver units A
and B will be set to free channels without mutual
interference . If no free channels are found, the set
channels will be kept .
Note: It is also possible to perform a channel scan for just
one receiver unit: Keep the appropriate arrow key (  for
unit A,  for unit B) pressed for approx . 1 second until
appears on the display .
Operation with two receivers TXA-802SR:
When two receivers TXA-802SR are simultaneously
operated and the four transmission channels are to
be set via channel scan, change the group setting
of both receivers:
1) Switch off the receiver units A and B . Then keep
the button SET pressed, while switching on a re-
ceiver unit . The display will indicate the current
group setting (with the digit flashing) .
2) Use the button  or  to switch to
