AC POWER CONNECTION AND AUTO ON/OFF
Your VULKKANO SUB8 subwoofer features auto on/off circuitry, marked
“auto” on the power switch, which automatically turns your subwoofer on
when it senses a program signal. We recommend the “auto” setting if your
subwoofer is always receiving power (ie, if it's plugged into a wall outlet).
When no signal is present, the circuit turns the subwoofer off after 15
minutes. If you are concerned about the brief delay between when the
music starts and when the subwoofer turns on, simply leave your
subwoofer in the “On” position. You may want to leave your VULKKANO SUB8
system unplugged during extended periods of non use, such as during a
vacation.
FINE TUNING YOUR SUBWOOFER
Volume - Adjust by ear using a wide variety of CDs and video sources.
Adjust for deep, powerful bass without “boomness”.
Low Pass - NOTE: This control adjusts the frequency range over which
the subwoofer operates.
When using smaller main speakers, the upper range of the control will
probably yield the best results. With larger speakers, the lower end of
the control range will probably sound best, but always let your ear be
the final judge. If male vocals sound “thin”, turn this control up until the
voice sounds rich but not “boomy”. If male vocals sound too “thick” or
“chesty”, turn this control down until the voice sounds natural.
Phase Switch - Sit in your favorite listening position. Play music (not a
movie) with a walking bass line. We recommend playing jazz or country
music. Now listen carefully for the point at which the subwoofer
transitions to your main speakers. This is the crossover point, and this
point should be below the frequency of a male human voice. Whichever
phase setting sounds louder or fuller at the subwoofer’s crossover
(transition) point is the optimum setting. Sometimes no difference will
be heard.
