1 Applications

This active speaker system of the series TXA-1020 is a combination of a two-way speaker system and a class D amplifier and is especially designed for mains-independent operation. For power supply, the unit is equipped with two lead gel batteries that are charged when the unit is connected to the mains. Thus, the unit is ideally suited for mobile PA applications, e. g. at events and lectures.

The active speaker system is equipped with controllable inputs for the connection of two microphones and two audio sources with line signal level (e. g. CD / MP3 player) as well as with two outputs (e. g. for the connection of another active speaker system). Audio data of a Bluetooth audio source (e. g. smartphone) can be reproduced via the integrated Bluetooth receiver. For operation with two wireless transmitters, the unit includes a two-channel receiver module (2 × 16 channels in the UHF frequency range 863.1 – 864.9 MHz). The transmitters of the series TXA-800, for example, may be used as wireless transmitters.

To operate the unit via the mains and /or to recharge the internal batteries, connect the mains cable provided to the mains jack (19) and to a mainssocket(230V/50Hz).

When the unit is connected to the mains, the batteries will be automatically recharged: During the recharge, the LED indicators for the battery status (4) will light up continuously one after the other. It is not necessary to switch on the unit for recharging; however, it can be operated during the recharging process. Once the recharging process has been completed, the LED "FULL" will light up continuously.

After operation or after recharging the batteries, disconnect the unit from the mains to avoid unnecessary power consumption.

5.2 Battery operation

During battery operation, the respective LED (4) will indicate the charging state of the rechargeable batteries:

FULL 80–100% charged
80% less than 80% charged
○ 50 % less than 50 % charged
- 20% less than 20% charged

Important: To prevent damage to the batteries due to deep discharge and to prevent a reduction of their lifetime, please observe the following notes:

• Always fully recharge the batteries prior to initial operation and after longer storage.
• When the LED "20%" starts flashing, the batteries are almost discharged and should be recharged as soon as possible.
  – Fully recharge the batteries prior to longer storage and at least every two months during storage.

6 Audio Connections

Switch off the unit prior to making any connection.

6.1 Inputs

Two microphones can be connected: via an XLR plug or a 6.3 mm plug, to the jack MIC 1 (18) or, via a 6.3 mm plug, to the jack MIC 2 (17).

Audio units with line signal level (e.g. CD / MP3 player, mixer, tape deck, tuner) can be connected to the RCA jacks LINE IN (13) and the 3.5 mm jack AUX IN (15). It is possible to connect both mono units and stereo units; in case of a stereo input signal, the left channel and the right channel are combined to a mono signal.

6.2 Outputs

Additional audio units such as a recorder or another active speaker system can be connected to the outputs LINE OUT and AUX OUT (14). At both outputs, the mixed signal of the audio sources will be available, unaffected by the tone controls (6) and the control MASTER (11). At each output jack – the two RCA jacks and the 3.5 mm jack – a mono signal is available.

7 Operation

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.

1) Prior to switching on the unit, set the control MASTER (11) to "MIN".

2) To switch the unit on and off, use the POWER switch (5). The switch will be illuminated when the unit is switched on. The battery status indicators (4) will indicate the charging status of the rechargeable batteries.

To prevent damage to the batteries by deep discharge during battery operation, a discharge protection will automatically switch off the unit when required. However, due to self-discharge of the batteries, a deep discharge may also occur when the unit is not operated for a longer period of time. Therefore, always observe the box "Important" in chapter 5.2.

3) Switch on the audio sources that are to be audible and then adjust their volume with the corresponding controls / buttons (see below); use the control MASTER (11) to adjust the overall volume for the active speaker system.

Volume adjustment of the audio sources:

– for the two receiver units of the 2-channel receiver module, use the corresponding volume control (2), CH.A or CH.B operation: see chapter 7.1

- for model TXA-1020USB:

for the integrated audio player, use the volume buttons at the player or on the remote control

operation: see chapter 3.1

– for a unit connected to the input AUX IN (15) and the Bluetooth receiver, use the volume control (8) of the operating panel AUX operation of the Bluetooth receiver: see chapter 7.2

Note: The control will determine the volume 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

Switch unused sources off or set their volume to minimum.

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 function. When the button is pressed (LED beneath the button illuminated), the volume of the music currently played will be substantially reduced while announcements 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) as well as on the output signal of the transmitter module.

7.1 Operating the receiver module

Using the 2-channel receiver module and two appropriate transmitters (e.g. pocket transmitter TXA-800HSE, wireless microphone TXA-800HT), two transmission paths can be established.

1) The receiver 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 receiver unit on, advance the corresponding control from the position "OFF". The left half of the display (1) applies to receiver unit A, the right half applies to receiver unit B. When a receiver 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, 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 transmitters switched off for the time being.

Channel scan:

Keep the buttons and simultaneously pressed for approx. 1 second until SCN appears on the display. The scan will start: The receiver units will be set to free channels without mutual interference. If no free channels are found, the channels set will be kept.

Manual channel selection:

If both receiver units A and B are switched on:

1. Keep the button SET pressed until the channel indication for receiver unit A starts flashing on the display.
2. Select the channel for receiver unit A with the button or and then confirm with the button SET.
3. The channel indication for receiver unit B starts flashing on the display. Select the channel for receiver unit B with the button or and then confirm with the button SET.

If only one receiver 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 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 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 transmitters are being received. In this case, select a different channel.

3) Switch the transmitters on and set them to the channels of the receiver module: Set one transmitter to the channel of receiver unit A and set the second transmitter to the channel of receiver 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 receiver unit.

If no reception is indicated or if the reception is poor, check if:

– the batteries of the transmitter are discharged.

– the reception is disturbed by metal objects or other high-frequency sources.
– the distance between the transmitter and the receiver 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 receiver modules)

The unit can be extended by another 2-channel receiver module (available as article TXA-1020MR). To set the four transmission channels via channel scan, change the group setting of both receiver modules:

1) Switch off the receiver units A and B. Then keep the button SET pressed while switching on a receiver unit. The display will indicate the current group setting F (with the number flashing).
2) Use the button or to switch to F2
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 exited after 5 seconds if no button is pressed. Any settings made will be saved.

Perform the channel scan for the first receiver module, switch on the appropriate two transmitters and set them accordingly. Leave the two transmitters switched on so that channels already used will be skipped during the channel scan for the second receiver module. Then perform the channel scan for the second receiver module, switch on the two appropriate transmitters and set them accordingly.

7.1.2 Setting the squelch

The squelch function will mute the respective receiver 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 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 receiver unit. The display will indicate the group setting (Fdr, with the number flashing).
2) Press the button SET to exit the group setting mode and to activate the squelch setting mode: 5 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 Bluetooth 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 Distribution Profile); otherwise, no wireless connection 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 connection to the Bluetooth source and that the Bluetooth receiver is ready for "pairing" (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 will be continuously illuminated once the linkage has been established.
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 disconnected (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.
