Connecting the amplifiers
Connect the DC power input of each amplifier with the supplied large 24 V AC
adapter (wallwart). The use of a surge protector is recommended to protect the
amplifiers from power surges which may damage the amplifiers and connected
speakers or may cause audio dropouts.
Each amplifier connects to regular passive loudspeakers via the supplied speaker
cable. Observe the correct polarity when connecting the speakers.
Connect the left speaker to the amplifier marked "LEFT". Connect the right
speaker to the amplifier marked "RIGHT".
ATTENTION!
Never short circuit any amplifier audio output since this may
damage the amplifier. A clicking noise may be generated during
amplifier power up. Therefore, it is recommended to connect power
to the amplifier prior to connecting the speakers.
Speaker connections:
Amplifier for left speaker
Left speaker
Connect the right speaker to the amplifier for the right speaker similarly.

Solution
In some cases, there may be
strong interference preventing
proper reception of the audio
signal which can be caused
by 5.8 GHz cordless
telephones or 5.8 GHz
wireless networks. Either
eliminate the interference,
locate the base unit of the
cordless phone in another
room, set the wireless
network to use the 5.1 GHz
frequency band rather than
5.8 GHz, relocate the
transmitter, relocate or
reorient the amplifier to
improve reception.
Ensure that the power outlet
delivers a stable voltage. Very
strong surges or voltage
fluctuations may cause audio
dropouts. Try using a surge
protector.
See under "Strong
Interference" above.
Adjust the transmitter volume
control.
See under "Audio signal too
weak" on previous page.
See under "Strong
Interference" above.
Audio will drop out if there are
too many obstacles between
the transmitter and the
amplifier (see page 4), try
relocating the amplifier or
transmitter to improve
reception.
