Step 1
Connecting the transmitter
The transmitter connects to a line-out interface via the supplied RCA cable.
Most audio devices provide a line-out interface.
If no line-out interface is available, the transmitter can also be connected to
other audio outputs by using an appropriate adapter. It should be noted that
the audio level of the audio output should conform to the standard line output
level (V ± 2.8 V maximum).
pp
If the audio level is too low, the dynamic range of the transmitter is not fully
used. If the audio level is too high, clipping at high audio levels may occur. If
clipping occurs, either use an adjustable output (such as a headphones
output) or use an Amphony audio level attenuator.
Connect the DC power input with the supplied AC adapter. The use of a surge
protector is recommended to protect the transmitter from power surges.
ATTENTION!
Never connect the DATA OUT output to an audio source since this
may damage both the transmitter and the audio equipment !

Step 2
Placing the transmitter
The operating range essentially depends on how many obstacles there are
between the transmitter and the headphones. 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.
If sufficient coverage can not be achieved by changing the location of the
transmitter, then the use of RangeBooster transmitters is suggested. These
RangeBooster transmitters are available as an accessory for your 2.4 GHz
Digital Wireless Headphones from Amphony and can be located in areas
where signal reception is difficult. RangeBooster transmitters connect to the
DATA OUT output of the transmitter and receive the signal in a digital format
without any degradation. Any number of RangeBooster transmitters can be
used to extend the operating range almost indefinitely.
