Step 1Step 1 Connecting the transmitter
The transmitter connects either to a standard line-out audio interface via the
supplied RCA cable or to an amplified speaker output via the supplied short
speaker cables.
If the transmitter is connected via speaker cables, observe the polarity of the
cable connection to ensure that the transmitter will be fed with a correct
polarity signal. If one of the cables is switched (reversed), one speaker will
receive an opposite polarity signal which will degrade sound performance.
The transmitter can also be connected to other audio outputs by using an
appropriate adapter.
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 5.8 GHz Digital Audio transmitter, one 5.8 GHz Digital Audio receiver,
two AC adapters, two dual RCA audio cables.
ATTENTION!
Do not use both the speaker cables and RCA cable. Do not
connect speakers to the transmitter.

Step 2Step 2 Placing the transmitter
The operating range essentially depends on how many obstacles there are
between the transmitter and the receiver. Therefore, it should be carefully
considered where to place the transmitter.
Below, two examples are given. In the first example, there are 4 walls
between the transmitter and the receiver. The transmission may be
interrupted. By locating the transmitter such as in the second example,
reliable transmission to all of the 6 rooms is possible.
Also, the elevation of the transmitter as well as the presence of reflecting
walls will influence the range.
It is suggested to experiment in order to find the best location for the
transmitter.
Example 1: Poorly chosen
transmitter location Example 2: Improved
transmitter location

Step 3Step 3 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.
For best reception, the receiver should be placed right side up and with the
front of the receiver facing toward the transmitter. The receiver employs a
directional antenna which prefers signals arriving at the front of the receiver.

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.

Step 4Step 4 Operating the transmitter and receiver
After powering up the transmitter, the transmit light will light for
approximately 5 seconds while the transmitter initializes.
After initialization, the transmit light will go out.
Once audio is detected at the audio input, the transmit light will light and the
transmitter will transmit the audio signal.
Switch on the speakers connected to the receiver. The audio will now be
played back through the speakers.
In order to properly set the transmitter volume control, turn the volume of the
speakers connected to the receiver to a low setting. Then feed a signal with
the highest possible volume to 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 connected speakers to the desired
level.
When no audio is present anymore, the transmitter will
go into standby mode after approximately 1 minute. The transmit light will go
out. During standby mode, no signal is transmitted.
Once the receiver is powered up and a valid audio signal is detected, audio
will be output at the receiver line output. When no valid audio signal is
received, the receiver audio output will be muted and the receiver will go into
standby mode.
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.
