Input Sources:
Any B&O radio or TV speaker out source.
Any analog audio source like a TV, a Sonos system,
an Apple AirPort Express, a Bluetooth receiver, a DAB
receiver or similar.
POWER LINK SPEAKER ADAPTOR
The PowerLink Speaker Adaptor makes it possible for two different sound sources to share one set
of active (powered) speakers, like Bang & Olufsen PowerLink speakers.

The PowerLink source will always have
priority over the AUX source. See the truth
table.
When detection of sound on the AUX input,
the Speaker Adaptor will power on the
speakers and loop the AUX source to the
speaker.
The speakers will remain powered on, until
no sound has been detected on the AUX
source for about a minute.

PLUG & PLAY OPERATION
There is no programming needed to make the adaptor work. When connected sound from one
connected device is lead to the speakers in accordance with below truth table.

FEA T U RES
GAL V ANI C ISOLATION
Using galvanic isolation the input signals are completely kept separate from each other.
This prevents problems with floating grounds and the two separate ground potentials for data and
audio.
Signal switching is made with a mechanical relay.
Data ground signal is switched with a mechanical relay.
Analog ground signal is switched with a mechanical relay.
Digital data signal flow via galvanic isolating optocoupler.
LOS S L E S S P OWE RLINK A UDIO PASS
The PowerLink audio signals pass without any modification; the output of the switch is the same
as the input.
DATALINK PASS
Datalink signals are passed to the output when the PowerLink source is active.

INS T ALLATION
The OneRemote PowerLink Switch is easily installed.
1. Connect the speakers with PowerLink cable(s). Not included.
2. Connect the two sound sources with appropriate cables. Not included.
3. Connect the mains adaptor.
CAB L E Q UALITY
Make sure to use good quality PowerLink cables, preferably double-shielded types, especially if
long cables are used. Do not use un-shielded cables for any connection.
PowerLink MKII with 4-wire mounted is not recommended.
Badly or non-screened cables pick up noise from the surroundings.
AUX S O UR CE N OISE REDUCTION
The AUX input can connect to any audio source. A regulated line output from a
preamplifier is one type of signal, a headphone output on a TV is another type.
Use the two NR DIP switches on the PowerLink Adaptor to match the source,
and thereby reduce noise. The switches must both be either up or down. Use
the position with the best result.
If noise disappears when pulling out the AUX plug, the noise is either being
picked up from cables, or the quality of the source may be poor.
In rare setups a humming low pitched noise can appear due to problems with ground planes. If
this occurs, an audio transformer can solve the problem.
AUX SOUND LE V EL
Use the two adjustments to align the level of the PowerLink and the AUX
source.
This adjustment also sets the maximum volume for the AUX source.

Non B&O TV, all Beo4 controlled
When the B&O radio is powered up,
sound from the radio is automatically
routed to the speakers.
When only the TV is powered up,
TV sound is routed to the speakers.
If Beo4 is modified with a OneRemote RMB4
converter, it can operate both the TV and the radio.
B&O system with PowerLink Speaker Adaptor
connecting:
AirPort Express, Bluetooth adapter, DAB+ tuner ….
Add music to any Bang & Olufsen system
wirelessly using Apple Airplay, Bluetooth
or cabled:
