WARNING The power supply unit uses danger- ous mains voltage. Leave servicing to skilled personnel only. Inexpert handling may result in electric shock.

The units are suitable for indoor use only. Protect them against dripping water, splash water and high air humidity. The admissible ambient tem- perature range is 0 – 40 °C.

Immediately disconnect the power supply unit from the mains

if the receiver or the power supply unit is visibly damaged,

2. if a defect might have occurred after the unit

was dropped or suffered a similar accident,

3. if malfunctions occur.

In any case the unit must be repaired by skilled personnel.

For cleaning only use a dry soft cloth; never use water or chemicals.

No guarantee claims for the units and no liabil- ity for any resulting personal damage or material damage will be accepted if the units are used for other purposes than originally intended, if they are not correctly connected or operated, or if they are not repaired in an expert way. If the units are to be put out of operation definitively, take them to a local recycling plant for a disposal which is not harmful to the environment 3 Applications The multifrequency receiver TXA-802SR works with 2 × 16 channels in the UHF frequency range 863 – 865 MHz. With two matching transmitters (e. g. TXA-800HSE, TXA-800HT, ATS-12HT), two wireless audio transmission paths can be established.

3.1 Conformity and approval

Herewith, MONACOR INTERNATIONAL declare that the receiver TXA-802SR complies with the directive 2014 / 53 / EU. The EU declaration of conformity is available on the Internet: www.monacor.com The receiver is generally approved for operation in EU and EFTA countries; it is licence-free and re- quires no registration. 4 Rack Mounting With the mounting material supplied, two receivers TXA-802SR can be inserted into a rack for units with a width of 482 mm (19”). In the rack, 1 RS (rack space = 44.5 mm) is required. Use two connection plates (one on the upper side, one on the lower side) to screw the two re- ceivers together. Screw a mounting bracket onto the left and right sides of the pair of receivers; then insert the pair of receivers into the rack by means of the mounting brackets.8 English 5 Setting the Receiver intoOperation

1) Place the receiving antennas (5) in a vertical po-

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).

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. Toswitch a receiver unit on, turn the control clock- wise from the position “OFF”. The left half of the display (3) applies to receiver unitA, the right half of the display applies to receiver unitB. 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).

wirelesstransmissionpaths 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.

Set the transmission channels for the receiver units A and B via channel scan or manually

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 being received. Inthiscase, select a different channel for the respective receiver unit.

2) Switch on the transmitters and set them to the

channel of receiver unitA and receiver unitB 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 12Example 2: channel 06 – channel 09 – channel 15 – channel 16

Keep the buttons and simultaneously pressed for approx. 1 second until appears on the display. The scan will start: The receiver units A andB 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).

3) To exit the group setting mode and to go to the

squelch setting mode (

chapter6.1.3), press the button SET. To exit the squelch setting mode, press the button SET. Note: The setting modes will be automatically exited after 5 seconds if no button is pressed. Any settings you may have made will be saved. Perform the channel scan for the first receiver, switch on the appropriate two transmitters and set them accordingly. Leave the two transmitters switched on so that the channels already used will be skipped during the channel scan for the second receiver. Then perform the channel scan for the second re- ceiver, switch on the two appropriate transmitters and set them accordingly.

6.1.2 Manual channel selection

If both receiver units A and B are switched on:

Keep the button SET pressed until the channel indication for receiver unit A starts flashing on the display.

Use the button or to select the channel for receiver unit A, then press the button SET to confirm.

3) The channel indication for receiver unit B starts

flashing on the display. Use the button or to select the channel for receiver unit B, then press the button SET to confirm. If only one receiver unit A or B is switched on: Keep the button SET pressed until the channel in- dication starts flashing on the display. Select the channel with the button or and then confirm with the button SET. If a channel is not confirmed within 10 seconds with the button SET, the setting mode will be exited and the channel previously set will be kept. Note: The receiver units A and B cannot be set to the same channel.

6.1.3 Setting the squelch

The squelch function will mute the respective re- ceiver unit when the level of the radio signal falls below the threshold value adjusted. Thus, interfer- ence signals will not cause noise when the trans- mitter is switched off or when its radio signal is insufficient: If the levels of the interference signals are below the threshold value, the receiver unit will be muted. A high threshold value offers high interference 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 transmitter and the receiver are far apart, a low threshold value is recommended.

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 group setting ( or , with the digit flashing).

2) To exit the group setting mode and to go to the
