SUB
Q CONTROL
The Q control allows you to tailor the bass's
character to your particular tastes and room
characteristics. (See the chart on page 2.) When
you make sensitivity or polarity changes, you may
also need to readjust the Q setting. These are
user controls and will not have any effect on the
room EQ settings. This control is adjusted while
listening to the plucked bass on test disc tracks 13
and 14. Bass should be one instrument and equal
weighting top to bottom of the scale.
INSTALLING THE SPIKES
When the best location for the SUB THREE(s) has
been found, turn the SUB THREE(s) over onto a
soft surface and install the spikes with the jam nuts
tightened against the bottom of the subwoofer. If
the SUB THREE(s) will be on a hardwood floor, a
spike shoe (available from the dealer) should be
placed under each spike to reduce the likelihood of
damage to the floor. With the spikes installed and
the placement finalized, the cables from the main
amplifier to the SUB THREE(s) can be shortened
as needed.
CROSSOVER OPTIMIZATION
Once the subwoofer(s) is broken-in, you should
again use the provided jazz recording with a stand-
up bass to evaluate the blend between the SUB
THREE(s) and the main speakers. Using the
switches inside the M5-HP crossover turn off amps
and set one setting above turn on the amps and
then listen. Then turn off the amp and reset one
setting below the original setting and turn the amps
back on and listen to the jazz recording. (Some
adjustments to the level and Q controls may be
necessary.) When you determine the best
crossover selection between the preamplifier and
power amplifier setting for your system, you are all
done.
SERVICE
In the unlikely event that your SUB THREE Subwoofer
System requires service, please follow these
procedures
1.Verify that the SUB THREE has been set up and
connected according to the Instructions In this manual.
Review the troubleshooting guide on the next page.
2.Download the R.M.A. Form and the Repair Instruction
Form and follow the troubleshooting.
3.The SUB THREE is a modular system.
4.Return the damaged or defective module and the
completed Return Authorization Form to Vandersteen
Audio. Any shipment of a complete SUB THREE to the
factory will be refused.
MAINTENANCE
All system connections should be cleaned periodically
with alcohol or a solution made specifically for cleaning
electrical contacts. The wood veneers are lacquered at
the factory and can be maintained with a light
application of Pledge or a similar product. The grille can
be vacuumed using a brush attachment that will not
snag the cloth. Care should be taken that objects that
could mar the finish are not placed on top of the SUB
THREE. The subwoofer should not be exposed to
excessive sunlight or heat, which can damage the fit
and finish of the veneer.
PACKING THE SUB THREE
To prevent physical or cosmetic damage, always pack
the SUB THREE in its original box with complete inner
packing prior to transportation or shipment. The proper
method of packing the SUB THREE is shown in the
illustration below. When you pack the SUB THREE, be
sure that the top and bottom spacers are oriented, as
shown in the illustration.
