Subwoofer adjustment options
Level
The level control on the C 80 SUB controls the volume.
Phase
When all the speakers in your system and the subwoofer have been connected it is
very important you have them connected in phase.
It is easier to adjust the phase on the subwoofer if you have someone helping you.
Sit in the listening area and ask your helper to turn the phase control while you’re
playing back bass-heavy music or the test frequency fi les found at www.Jamo.com
or on the CD-rom which came with the product. Turn the control back and forth to
determine the position where the overall bass level sounds the loudest; that’s when
you’ll know the subwoofer is in correct phase.
Note that it may help to turn the volume of the subwoofer up when correcting the
phase. Regardless, you may also need to turn the subwoofer volume down after
fi nding the correct phase position, as it increases the overall bass output from the
subwoofer.
