System Configuration #3
System: A stereo preamp or processor that has line-level connections to a separate
power amp but lacks a separate subwoofer output.
Connections:
•
Disconnect the outputs of your preamp or processor from the inputs of your power amp and
connect them to the Left Input and Right Input on the Flex Sub.
•
Connect the Left Output and Right Output of your Flex Sub to the left and right inputs on
your power amp.
Configuration:
•
Set the Power switch to Auto so your Flex Sub will turn on automatically when the music
starts.
•
With the Phase switch, try both settings, and leave it set in the direction where you hear the
most low bass (at your listening position).
•
Set the High-Pass Crossover Frequency switch to select the bass management crossover point
for your system. The industry standard setting is 80 Hz, which is a good starting point, but you
may find that one of the other settings provides for a smoother transition with your particular
speakers.
•
Start with the X-Over control set to the same frequency as you've chosen for the High-Pass
Frequency setting. However, you may need to adjust it so you get the smoothest transition
between the Flex Sub and your main speakers. The correct setting will depend on your room
and your other speakers.
•
Adjust the Volume control so that the level of the Flex Sub matches the level of your other
speakers. The output of the sub should blend smoothly with your other speakers and you
should not hear the sub as a separate source of sound.
Notes:
•
For best noise performance, try to keep the cable lengths between your source, your amplifier,
and your Flex Sub as short as possible.
