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.
