Protective Circuits - Monacor SAM-2 Manual De Instrucciones

free-standing speakers are optimally comple-
mented with a crossover frequency adjusted
between 60 Hz and 100 Hz .
4) Adjust the volume ratio to the other speakers
with the control SUB LEVEL (3) . Thus, a natural
or a deliberately amplified bass reproduction
can be adjusted .
5) Adjust the phase for the subwoofer with the
control SUB PHASE (7) . Depending on the acous-
tic conditions, this adjustment is more or less
audible . The phase can best be adjusted during
a music piece with an electric bass, a contrabass,
or a deep bass voice . Set the control SUB PHASE
to the bass reproduction of the highest volume .
Then slightly turn back the control SUB LEVEL,
if required .
6) Use the control SUB-BOOST LEVEL (6) to boost
certain frequencies in the low bass range up to
6 dB . Adjust the frequency for the bass boost
with the control SUB-BOOST FREQUENCY (5) .
7) Use the control SAT CROSSOVER (8) to adjust
the lower crossover frequency for the satellites,
i . e . the frequency not to be reproduced any
more by the satellite speakers . Thus, the am-
plifier for the satellite speakers will be relieved
from the low frequencies .

7 Protective Circuits

For protecting the power amplifier of SAM-2 and
the subwoofer connected, various protective cir-
cuits are provided:
1 . In case of a short circuit or direct voltage content
at the output for the subwoofer, the module
will immediately go on stand-by . Switch off
the module with the switch POWER (10) and
ask skilled personnel to eliminate the problem .
Switching off the module will reset the protec-
tive circuit .
2 . In case of overheating, the module will also go
on stand-by . Ventilation of the heat sink (1)
must be improved . After cooling down to nor-
mal operating temperature, the module will be
switched on again .
