5. Adjust the volume of your radio to approx.
90 % of the max. volume and playback an
appropriate test tone, e.g. pink noise (0 dB).
6. If the clipping indicator in the DSP PC-Tool
already lights up (see picture below), you
have to reduce the input sensitivity using the
scroll bar until the indicator turns off.
7. Increase the input sensitivity until the clip-
ping indicator lights up. Now turn the control
back until the indicator turns off again.
10. Configuration of the internal DSP
The general amplifier settings should be
conducted with the DSP PC-Tool software
before using the amplifier for the first time.
Now you are able to configure your UP 8DSP
with our intuitive DSP PC-Tool software. Useful
hints for the correct setting can be found in our
knowledge base at www.audiotec-fischer.com.
Caution:
We highly recommended to set the
volume of your car radio to minimum position
and to mute all signal outputs. Especially if the
UP 8DSP will be used in fully active applica-
tions, a wrong setup can destroy your speakers
right away.
11. Analyzing the input signal
Check the input signal for factory-set equal-
izing and all-pass filters using the Input
Signal Analyzer (ISA) of the DSP PC-Tool
software. Information about the ISA can be
found in the extensive Knowledge Base on
our website
www.audiotec-fischer.com
.
Caution:
We highly recommend to set the
volume of your car radio to minimum position
during first start-up. Additionally no device
should be connected to the amplifier until gen
-
eral settings in the DSP PC-Tool software have
been made. Especially if the UP 8DSP will be
used in fully active applications, a wrong setup
can destroy your speakers right away.
12. Optional: Connecting the pre-amplifier out
-
put
The
Line Out
is a mono floating-ground low level
output for connecting an additional power am-
plifier. This output can now be connected to the
pre-amplifier / lowlevel / RCA input of the exter
-
nal amplifier using an appropriate cable (RCA /
Cinch cables).
The output provides a maximum output voltage
of 3 Volts RMS.
Please make sure that you always turn on / off
the external amplifier using the remote output
(
REM OUT
) of the UP 8DSP in order to avoid
interfering noises.
