3 Applications and Accessories

In combination with a receiver tuned to the same radio frequencies, this PLL multifrequency transmitter allows to set up a wireless mono audio transmission system. The signal of the transmitter can be sent to any de sired number of receivers. Thus, the system is ideally suited for applications where the signal of an audio source is fed to several people, e.g. guided tours or multilingual lectures. For radio transmission, 16 channels in the UHF range from 863.1 MHz to 864.9 MHz are available.

The transmitter can be combined with the following MONACOR receivers:

UnitType
ATS-16R pocket	receiver
TXA-800R pocket	receiver
TXA-802SR main	s-operated two-channel receiver
TXA-820	battery-operated active speaker system with receiver
TXA-820CD
TXA-822CD	battery-operated active speaker system with two-channel receiver
TXA-1020	battery-operated active speaker system with two-channel receiver
TXA-1020USB
TXA-1022CD

The transmitter has two microphone inputs (balanced and unbalanced, with +5V T-power to be activated) and an input for a unit with line output level (e.g. CD player) to be monitored via headphones. A line output allows connection of an amplifier or a sound recorder.

Installation material is provided for installing two TXA-800ST transmitters into a rack. The second transmitter can be supplied with power via the DC voltage output of the first transmitter.

3.1 Conformity and approval

Herewith, MONACOR INTERNATIONAL declare that the transmitter TXA-800ST complies with the directive 2014/53/EU. The EU declaration of conformity is available on the Internet:

www.monacor.com

The transmitter is generally approved for operation in EU and EFTA countries; it is licence-free and requires no registration.

4 Rack Installation

Two TXA-800ST transmitters can be installed into a rack for units of a width of 482mm (19^ ) via the installation material provided. In the rack, 1 RS (rack space = 44.5mm ) is required. Connect the transmitters by means of the two adaptors on the upper and lower sides, then fasten the two brackets with four screws each to the left and right sides of the transmitter pair and use the brackets to install the transmitter pair into the rack (figure 3).

5 Connection

1) Screw the antenna provided onto the TNC jack ANTENNA (14) and put it in a vertical position.
2) The transmitter has two microphone inputs MIC IN for connecting a microphone:

• When the microphone is balanced, use the XLR jack (17).
• When the microphone is unbalanced, use the 6.3mm jack (19); in case of a 3.5mm plug on the microphone, insert a corresponding adapter.

In case of an electret microphone requiring a 5V operating voltage, activate the +5V T-power for the 6.3mm jack: set the switch (18) next to the jack to ON.

Caution

• Do not activate the T-power when a dynamic microphone is connected to the 6.3mm jack; otherwise it may be damaged!
• Only activate/deactivate the T-power when the unit is switched off; otherwise, this will cause loud switching noise.

3) The stereo input LINE IN (16) allows to connect an audio unit with line output (e.g. CD player, tape deck, radio).

To monitor the input signal of the jacks LINE IN [unaffected by the volume control AUX (4) and by the position of the button TX (5)], connect headphones to the 6.3mm jack (13).

4) The output LINE OUT (15) will get the same signal as the transmitter section [i.e. the signal of the audio source selected with the button TX, (3) or (5), or the mixed signal of the audio sources when both buttons TX are pressed]. A mono signal is available at both RCA jacks, e.g. for connecting the line input of an amplifier or sound recorder.
5) For power supply, connect the power supply unit provided to the jack POWER IN (21) and to a mains socket (230V / 50Hz)

If a second transmitter TXA-800ST is used, it can be supplied with power via the first transmitter: connect the jack POWER OUT (20) of the first transmitter via a cable with low voltage plugs (plug dimensions chapter 7) to the jack POWER IN (21) of the second transmitter.

6 Operation

Prior to switching on, turn the volume controls MIC (2) and AUX (4) counter-clockwise to the left stop.

1) To switch on the unit, press the POWER switch (1): The switch will light up.
2) Adjust the transmission channel on the corresponding receiver (operating instructions of the receiver).
3) Turn the control (11) of the transmitter section clockwise until it is switched on: The transmission LED TX

(7) will light up and the display (6) will indicate the channel currently adjusted.

4) Adjust the same channel as on the receiver:

a) Press the button SET (9) until the channel indication starts flashing on the display (6).
b) While the channel indication keeps flashing (for approx. 10 seconds), the arrow buttons (10) allow to select the channel: button for upward selection of channel, button for downward selection of channel.
c) Confirm the channel selection with the button SET (9). If the selection is not confirmed within 10 seconds, the transmitter section will switch back to the previous channel.

Note: In case of receiver ATS-16R, the channels are marked 0 to F: Channel 0 corresponds to channel 01, channel 1 corresponds to channel 02, ..., channel F corresponds to channel 16.

During operation it is possible to briefly indicate the radio frequency for the channel adjusted: As long as the button or (10) is kept pressed, the display will indicate the frequency instead of the channel.

5) To switch an audio source to the transmitter section and at the same time also to the line output (15), press the corresponding button TX: (3) for the microphone, (5) for the unit at the line input. When a button is pressed, the corresponding LED ON will light up.

With the corresponding volume control VOL, adjust the level at which the signal of the audio source is fed to the transmitter section and the line output: (2) for the microphone, (4) for the unit at the line input.

6) The LEDs AF LEVEL (8) will indicate the level of the audio signal fed to the transmitter section:

The yellow LED will light up when the signal has reached a defined minimum level.

The red LED will light up when the signal has reached the maximum level at which it is close to distortion. The LED should not light up at all or only light up briefly with signal peaks; if it lights permanently, the signal is distorted. In this case, reduce the volume of the corresponding audio source / sources accordingly.

7) Use the control (11) of the transmitter section to adjust the volume at which the audio signal is transmitted to the receiver.
8) When headphones are connected, adjust the headphone volume with the control PHONE VOL (12).

Caution! Never adjust the headphones to a very high volume. Permanent high volumes may damage your hearing!

9) For switching off the transmitter section turn its control (11) counter-clockwise until it is switched off.

For switching off the unit completely, press the switch POWER (1). If the unit is not used for a longer

period, disconnect the power supply unit from the mains socket as it will even have a low power consumption when the unit is switched off.

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 interference 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
