Subwoofer Input connection
Some receivers, amplifiers or sound processors have
low-level, monophonic subwoofer outputs. If your
equipment has this type of an output, conect it to either
of the Low Level inputs. Be sure to set the Bass Mode
switch
9 to EXT.
Note: When the Bass Mode switch is set to the EXT posi-
tion the subwoofers Crossover Frequency control 8 and
the Level Control 4 are bypassed. The electronics sup-
plying the signal controls the crossover frequency and
the subwoofer level. If the crossover frequency of the
component providing the subwoofer output signal is not
adjustable, it may not produce the best subwoofer-to-
main speaker transition. In such cases it is better to use
a full-range low level input from the source electronics
and let the subwoofer amplifier control the crossover.
Low Level connection
Whenever possible connect the subwoofer to
the system through low level (also called line
level) input and output connections. Even if you
do not have a separate preamp and power amp,
many receivers and integrated amplifiers include
Preamp Out and Amplifier In connectors.
Connect the Preamp Outputs of your system to
the Low Level In connectors of the subwoofer
amplifier. When using the low level connec-
tions, the signal from the High Pass Outputs is
returned to your amplifier which will drive the main
speakers in the system. This output is high pass filtered
to remove sound below frequency set by the Crossover
Low Pass Filter Control. See the Fine Tuning section of
this manual for more information.
