Step1
Connecting the transmitter
With the transmitter, you can send music from your iPod / iPhone or from any
audio source that either provides a line-level audio signal or amplified speaker
level signal.
Depending on what type of audio signal you wish to transmit, follow one of the
below guidelines:
a) Transmit music from an iPod / iPhone
Place your iPod or iPhone into the iPod cradle located at the top of the
transmitter. Ensure the iPod / iPhone display faces towards the front of the
transmitter.
b) Transmit music from a line-level audio source
Attach the small silver jack of the supplied Y adapter audio cable to the line
level audio input of the transmitter. Then connect the two RCA plugs to your
audio source.
c) Transmit music from an amplified source
In order to transmit music from an amplified audio source, attach the two
supplied speaker cables to the speaker outputs of your source and then to the
speaker jack of the transmitter. Please ensure the correct polarity of the cable.
The transmitter can also be connected to other audio outputs by using an
appropriate adapter.
Finally, connect the supplied small AC adapter’s barrel-shaped plug into the
DC 9V jack, and then plug the transformer into a standard AC outlet. We
recommend the use of a surge protector to protect the transmitter from power
surges.
Unpacking: Check that this package contains:
One audio transmitter, one audio receiver, two AC adapters, two audio cables.

Step2
Connecting the receiver
The receiver connects to a line-in interface of an active speaker or external
amplifier via the supplied RCA cable.
If no line-in interface is available, the receiver can also be connected to other
audio inputs by using an appropriate adapter. It should be noted that the
maximum audio level of the receiver output is 1 Vrms (V ± 1.4 V maximum).
pp
Ensure that the connected audio device will accept this audio level.
Connect the DC power input with the supplied AC adapter. The use of a surge
protector is recommended to protect the receiver from power surges which
may damage the receiver or may cause audio dropouts.

Step3
Pairing the transmitter and receiver
In order for the transmitter and receiver to communicate, they need to be
paired. To pair the transmitter and receiver, push the transmitter pairing
button. The transmit light will start flashing.
Next, push the pairing button of the receiver which is located on the bottom
of the receiver.
You must push the receiver pairing button within one minute after you have
pushed the transmitter pairing button.
You can add up to 3 more receivers to receive the signal from the transmitter
(maximum of 4 receivers in total). Pair each additional receiver as shown
above.

Step4
Setting the transmitter volume control
The transmitter perfroms advanced analog-to-digital transmission of the
audio signal. In order to achieve maximum dynamic range and avoid clipping
of the audio, the transmitter volume control must be adjusted to your audio
source.
In order to properly set the transmitter volume control, turn the volume of the
device connected to the receiver to a low setting. Then feed a signal with the
highest possible volume into the transmitter. Set the transmitter volume
control to the highest level while there is still no clipping / distortion of the
audio signal. Then set the volume of the device connected to the receiver to
your desired level.
If the transmitter or receiver are not used for an extended period of time,
remove the AC adapters from the power outlet.
If the transmitter level is set too low, the dynamics of the transmission are
not fully used. If the level is set too high, audio clipping (distortion) will occur
inside the transmitter during the analog-to-digital conversion.
ATTENTION! Do not connect the receiver audio output directly to passive
speakers or other low impedance drains as this may damage
the receiver! The receiver audio output cannot drive passive
speakers or headphones directly. For those devices, an
external amplifier is required.

Troubleshooting
Problem Possible Cause Solution
The transmit light
does not go on after
DC power is applied
to the transmitter
Faulty AC adapter
or faulty power outlet
Check the power outlet and
the AC adapter; if possible,
check for correct voltage of
the AC adapter.
No audio present at
audio input
Check the audio connection
to the transmitter and ensure
that there is audio present.
The transmit light
goes out after a few
seconds and does
not light again Transmitter hung up Disconnect and then
reconnect DC power.
Faulty AC adapter
or faulty power outlet
See under “Faulty AC adapter
or faulty power outlet“ above.
Transmitter volume
control set too low
Adjust the transmitter volume

Interference“ on next page.
Transmitter volume
control set too high
Adjust the transmitter volume
control until clipping stops.
Audio is distorted
Strong interference See under “Strong
Interference“ on next page.
Transmitter volume
control set too low
Adjust the transmitter volume
control to achieve the desired
audio level.
Speaker volume
control set too low
Adjust the speaker volume
control to achieve the desired
audio level.
Speaker audio level
is too low

weak
Increase the output level of
the audio source (connect
transmitter to an adjustable
output by using an adapter if
necessary).

POWER SOURCE
To avoid product malfunction, and to protect against electric shock, fire or personal
injury, please observe the following:
• This product has been designed to work with 120-volt AC current using the
supplied AC adapters. Connection to a line voltage other than that or use of non-
compatible AC adapters may create a safety and fire hazard and may damage
the product.
• Do not run power cords under rugs or carpets or place heavy objects on them.
• Damaged or deformed power cords are hazardous and should be replaced
immediately by a qualified service technician.
LOCATION
• Do not use this product outdoors or in cars.
• Air vents are provided at the bottom of the receiver to prevent excessive
temperatures inside the unit. Do not place the receiver in closed spaces, cover it,

• Do not place this product in direct sunlight, or near heat sources.
• Keep this product away from strong magnetic objects.
VOLUME CONTROL
• Do not turn up the volume while listening to a portion with very low level input or
no audio signal to avoid damage to your speakers during a peak level audio
portion.
• Turn the speaker volume control to minimum prior to connecting or disconnecting
the transmitter or receiver and prior to switching audio sources as this may cause
loud clicks which can damage your speakers.
CARE
• Do not insert or drop anything into the receiver through the air vents as this could
cause serious damage, possibly resulting in fire.
• Do not place any object containing water or other liquids on this product.
