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

Bluetooth® Audio Transmitter | 9
Getting started
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).
XSwitch your audio source off before connecting the transmitter.
XCheck the connection options available on your audio source (for analog
audio connection, the audio output is usually marked “OUT”).
XSelect the corresponding connection cable and, if necessary, a suitable
adapter.
XOnce the cable is selected, slide the Input Selection switch toward the
correct input.

Getting started
Connection to an audio source using the digital optical cable
To 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.

Pairing the transmitter to the headphones
CAUTION
Danger of malfunction!
The transmitted radio waves of Bluetooth devices can impair
the operation of sensitive and unprotected devices.
XOnly 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 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.

Using the transmitter
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.
WARNING
Danger due to high volume levels!
Listening at high volume levels can lead to permanent hearing
defects.
XBefore 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.
XDo not continuously expose yourself to high volume levels.
XSlide 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).
XSlide 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 a 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.

Using the transmitter
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 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.
XPair and connect your headphones to the transmitter, and then connect
the transmitter to the TV/PC, see page 13.
XPlay music/videos from your TV/PC.
