Getting started

Setting up the Bluetooth® Audio Transmitter
  • Choose a suitable place near your audio source.
  • Avoid placing the transmitter and other wireless devices too close to one another to prevent interference.
  • Do not place the transmitter close to metal objects such as shelf bars, reinforced concrete walls, etc. as this can decrease the transmitter’s range.

Connecting the Bluetooth® Audio Transmitter to an audio source

You can simultaneously connect 2 different audio sources (e.g. a TV or PC and a stereo hi-fi system) to the transmitter. The transmitter features a digital as well as an analog audio input. If you connect 2 audio sources, you can toggle between them using the Input Selection switch (see page 15).

  • Switch your audio source off before connecting the transmitter.
  • Check the connection options available on your audio source (for analog audio connection, the audio output is usually marked “OUT”).
  • Select the corresponding connection cable and, if necessary, a suitable adapter.
  • Once the cable is selected, slide the Input Selection switch toward the correct input.

Connection to an audio source using the digital optical cableTo achieve the best possible listening experience, we recommend that you connect the Bluetooth® Audio Transmitter to your home cinema or hi-fi system using the supplied digital optical cable.

Your Bluetooth® Audio Transmitter allows digital audio streaming using only PCM audio output from devices connected through the digital optical input. Refer to the sound menu or the instruction manual of your TV to change from another audio stream (e.g. Bitstream) to PCM.

* The appearance of the Sound menu can vary depending on the device used.

Pull off the clear protective caps from both plugs of the digital optical cable before connecting to the TV and transmitter.

  • Switch your audio source off before connecting the transmitter.
  • Slide the Input Selection switch toward the Digital Optical IN input.
  • Connect one end of the digital optical cable to the Digital Optical IN the input of the transmitter and the other end to the optical output of your TV.

Connection to an audio source using the 3.5 mm analog audio cableSome TV models mute the loudspeakers when you connect the transmitter to the headphone socket. Check in the menu of your TV to see if the muting function can be deactivated.

  • Connect the 3.5 mm plug of the analog audio cable to the Analog input of the transmitter.
  • Connect the other end of the analog audio cable to the 3.5 mm headphone socket of the TV or PC.

Powering the transmitter
  1.  Connect the USB micro B plug of the supplied USB power cable to the USB-B port of the transmitter.
  2. Connect the USB plug to the USB port of your TV or PC. For older TV models without a built-in USB port, connect the USB plug to an external USB power adapter and connect to the power source. The transmitter automatically switches on.

 

Pairing the transmitter to the headphones

CAUTIONThe danger of malfunction!The transmitted radio waves of Bluetooth devices can impair the operation of sensitive and unprotected devices.

  • Only use Bluetooth devices in locations where wireless transmission is permitted.

The transmitter can save the connection profiles of up to eight Bluetooth headphones. If you pair the transmitter to the ninth headphones, the saved connection profile of the least used headphones will be overwritten.

If you are watching/listening from your home entertainment system, the transmitter can connect to up to 2 headphones simultaneously.

Pairing the transmitter to the headphones

  1. Set your headphones to pairing mode. If you are using Sennheiser headphones, the headphones’ LED usually flashes blue and red during pairing.
  2. Press the Multifunction button on the transmitter for 4 seconds. The transmitter goes into pairing mode and the LED flashes blue and red. If pairing is successful, the LED flashes and then lights up blue for approximately 3 minutes.

 

 

If no connection is established within 5 minutes, pairing mode is terminated and the transmitter goes into standby mode. If necessary, repeat the pairing procedure.

Using the transmitter

Switching the transmitter on

The transmitter goes into pairing mode when switched on for the first time.

  1. Press the Multifunction button for seconds. The LED lights up red.

 

 

Switching the transmitter off
  1. Press the Multifunction button for 3 seconds. The LED switches off.

 

Selecting an audio input

If both the analog and the digital audio input are connected to an audio source, the transmitter allows you to toggle between the two inputs.

WARNINGDanger due to high volume levels!Listening to high volume levels can lead to permanent hearing defects.

  • Before putting the headphones on and before toggling between your audio inputs, adjust the volume on the headphones to a low level. Toggling between inputs may cause enormous volume jumps that can damage your hearing.
  • Do not continuously expose yourself to high volume levels.
  • Slide the Input Selection switch toward the Digital Optical IN input to listen to an audio source connected using the digital optical cable (see page 10).
  • Slide the Input Selection switch toward the Analog 3.5 mm IN input to listen to an audio source connected using the analog audio cable (see page 11).
Connecting the transmitter to the headphones

Connect the headphones to the transmitter to watch a movie or listen to music from your TV, PC, or home entertainment system.

  1. Switch the paired headphones on.
  2. Switch the transmitter on. The LED lights up red. Once the connection is established, the LED lights up blue.

 

Connecting the transmitter to the second pair of headphones

The aptX Low Latency codec is not supported when 2 headphones are connected to the transmitter. With this configuration and depending on other factors, such as the models of the headphones used, the synchronization of audio to the TV picture may not be completely guaranteed.

You can quickly connect another pair of headphones while the first pair of headphones is streaming audio. While the second pair of headphones is connecting to the transmitter or is leaving the transmission range or re-entering it, the first headphones may experience an audio interruption until both pairs are connected to the transmitter.

  1. Set the second pair of headphones to pairing mode.
  2. Press the Multifunction button of the transmitter for 1 second. The LED lights up red. Once the transmitter detects that 2 pairs of headphones are connected, the LED lights up purple for 3 minutes.

*1 Set to pairing mode.

Playing music/videos

If your audio source and headphones support the aptX or aptX LL codec, the Bluetooth® Audio Transmitter plays your music wirelessly in stunning audio quality. If the audio source and headphones do not support any of these audio codecs, the audio is played in standard quality.

When watching videos from a TV/PC that supports an aptX Low Latency codec, the synchronization of sound to the visual media is automatically optimized. This means that the audio remains in sync with the video all the time.

When the transmitter is connected to 2 pairs of headphones, the audio on both headphones will be played in either aptX or standard quality. With this configuration and depending on other factors, such as the models of the headphones used, the synchronization of audio to the TV picture may not be completely guaranteed. 2-headphone configuration is best utilized especially for home audio listening.

  • Pair and connect your headphones to the transmitter, and then connect the transmitter to the TV/PC, see page 13.
  • Play music/videos from your TV/PC.

Care and maintenance

CAUTIONLiquids can damage the electronics of the product!Liquids entering the housing of the product can cause a short circuit and damage the electronics.

  • Keep all liquids away from this product.
  • Do not use any solvents or cleaning agents.

To clean the Bluetooth® Audio Transmitter:

  • Switch the transmitter off and disconnect it from the power source before cleaning.

Troubleshooting

 

Leaving the Bluetooth transmission rangeWireless streaming is only possible in the Bluetooth transmission range of your Bluetooth devices. The transmission range largely depends on environmental conditions such as wall thickness, wall composition, etc. With a free line of sight, the transmission range of most Bluetooth devices is up to 30 meters.

If the headphones leave the Bluetooth transmission range of the transmitter, the sound quality deteriorates until the connection breaks down completely. You can re-establish the connection when you re-enter the Bluetooth transmission range of the transmitter.

 

Clearing the previously pairing settings

All previously paired headphones are cleared from the transmitter. Ensure that the transmitter is switched off when performing this procedure.

  1. Press the Multifunction button for 10 seconds. The LED flashes blue 5 times and the transmitter returns to off state immediately.
