Place the speakers on an even surface and align
them to the ears of the listener. The tweeters
should be at earʼs height, if possible.
Do not place the speakers too close to walls or
in corners as this will falsify the frequency response
and impair the heat dissipation of the installed
amplifier.
4.1 Connecting the right speaker system
Connect the amplifier output SPEAKER OUT (9) on
the rear side of the left speaker system to the input
of the right speaker system. Pay attention to the
polarity (connect terminals of the same colour).
4.2 Connecting the signal source
Connect the output of a signal source with line level
(e. g. CD player, mixer output, line output of a com-
puter or TV set) to the RCA jacks (7) on the rear
side of the left speaker system (L = left channel,
R = right channel).
Alternatively, connect the computer via the jack

been connected to the computer being operated,
the operating system of the computer recognizes it
as a USB audio unit (sound output). If required,
install the drivers required by the operating system
and restart the computer.
The USB interface is equipped with a function
to reduce the dynamic range of the audio signal
(DRC = dynamic range control). This function is
switched on automatically, but can be deactivated
via the Windows operating system (not possible
for Mac OS ). Screenshots as examples of the
steps required under Windows XP and Windows 7
(German version) can be found on the last pages of
this instruction manual.
In the Control Panel ("Sounds and Audio
Devices" or "Hardware and Sound"), select "USB
Sound Device" for "Sound playback" (this is usually
made automatically after connection to the com-
puter). Via the advanced settings of the volume
control in the window "Advanced Settings for
Speaker", uncheck the box under "Other Settings"
or on the tab "Custom" for Windows 7 .
4.3 Power supply
Connect the plug of the mains cable (6) to a mains
socket (230 V~ / 50 Hz).

5 Operation

CAUTION Never adjust the audio system to a
very high volume. Permanent high
volumes may damage your hearing!
The human ear will get accustomed to
high volumes which do not seem to be
that high any more after some time.
Therefore, do not further increase a
high volume after getting used to it.
Note: To prevent switching noise, always switch on
the speakers after the units connected and
switch them off first after use.
1) Set the control VOLUME (1) to MIN (left stop)
first and switch on the speaker system with the
POWER switch (4). The LED on the front side
lights up.
2) Adjust the desired volume with the control VOL-
UME (1). Only turn up the control so far that the
sound will not be distorted.
3) Adjust an optimum sound with the controls TRE-
BLE (2) and BASS (3).
4) After use switch off the speaker system with the
POWER switch.
