Spinsub fits perfectlyon the bottom shelf
of
Spinstand without causing vibrations
that

LOW-PASS
FREQUENCY
-Use this
to
adjust the low-pass crossover
of
the subwoofer
amplifier. Sound above the selected frequency is attenuated at 12dB per octave. The
recommended setting for use with Spinbase is 80Hz, which is achieved with the knob
adjusted
to
the center position. You may prefer a differentsetting, so feel free
to
adjust
it
to
your taste.
SUBWOOFER
LEVEL
-Adjust the volume level
of
the subwoofer
to
your preference.
Leaving
this
control centered will typically provide a good sonic blend with Spinbase.
However, the
optimum
setting will depend on the room, and placement
of
the unit
within the room.
POWER
INPUT -Connect the power cable into the wall outlet. Spinsub is compatible
with worldwide voltages
from
100v-240V
AC
at
50 or 60 Cycles. A suitable plug
adapter will
be
required for use in areas outside North America.
LINE/
SIGNAL INPUT -Use this input
to
connect your Line-level source to Spinsub.
POWER
STATUS
LED
-The
LED
illuminates brightly when Spinsub is on and active,
and will extinguish when Spinsub enters Standby mode.
POWER
SWITCH -Set
to
the
ON
position for normal use. Spinsub has a signal sens-
ing standby
mode
that
consumes lessthan 0.5 Watts when idle, so power may
be
left
on. Set this switch
to
the
OFF
position
if
you will not be using Spinsub
for
an
extend-
ed time,
or
to
protect
it
from power surges during electrical storms.

How
to
Connect
your
Source
Spinsub has beed optimized
for
use with Spinbase, but
it
also may be used with
othersource components. It requires a source component
that
has a line-level
output controlled by its volume control. This may be labeled
in
a number
of
ways,
depending on your source component.
Most
common are:
Pre-Out (or Preamp out)
• Subwoofer
Line Out
Aux Out
An
RCA
to
Miniplug adapter cable is included with Spinsub
to
facilitate use with
sources otherthan Spinbase. Spinsub does
not
accept speaker-level inputs.
If
you wish
to
add Spinsub
to
a system that has only Speaker level output, you
must
use a Line Output Converter accessory.
IMPORTANT
NOTE
Spinsub is compatible with Spinbase units
that
have a separate Line output only.
Earlier Spinbase units with only a Headphone
jack
output are
not
compatible, but
may
be updated
at
a nominal cost. Contact [email protected]
for
more
information.
Using
Spinsub
Turn on the main power using the rear panel switch. The green
LED
will illumi-
nate.
It is not necessary
to
switch the power
off
between listening sessions. Spinsub
has automatic signal sensing. When a signal is present, Spinsub will wake from
standby and begin playing. It will reenter standby aftera
few
minutes
of
no sig-
nal.
If
there is excessive hum
or
noise in the input signal, Spinsub may
not
enter
standby.
If
this occurs please identifythe source
of
the noise and eliminate
it
for
the
most
satisfying experience.
The
LED
indicates status. The
LED
glows brightly when Spinsub is active, and
will extinguish when the unit is in standby.
If
the
LED
remains
off
when signal is
present, Spinsub is
not
receiving power orthe main power switch has
not
been
turned on.

Room
Placement
and
Tuning
As with any speaker, its location in your room affects howthe sound fills the
space. Sound is emitted
from
both sides
of
Spinsub, so be careful
not
to
block
the sides.
Thanks
to
lsogroove vibration reduction technology, Spinsub may be placed on
the bottom shelf
of
Spinstand
without
disturbing phono playback.
The long wavelengths
of
low frequency sounds exceed the dimensions
of
most
domestic rooms. As a result, the sound reflected
from
the walls create
"standing waves" which reinforce bass in some locations, and cancel bass in
others. Understanding howthese standing waves work within your particular
room is important
to
getthe
most
satisfying overall performance. Movingthe
Spinsub a
few
feet either way can have a dramatic effect on perceived bass
response. There is no "one size fits all" solution
that
is best
for
every room, so
experimentation in your specific room is essential.
Pracing the subwoofer directly in the center
of
a wall can often make the effect
of
standing wave reflections more pronounced. It is usually best
to
place the woofer
a
few
feet
to
either side
of
center.
Corner placement will yield the strongest reinforcement
of
bass within the room,
but mayalso further exacerbate standing waves.
You
will need
to
try
various
locations
to
determine
what
location works best in your particular room.
Depending on the location you choose, you may require a longer cable than
the one supplied. Make sure whatever cable you purchase is a shielded type
to
prevent excessive noise pickup.
Make final adjustments
to
the Low-Pass crossoverfrequency and level once you
have determined thefinal location. The
most
satisfying performance will occur
when the subwoofer is loud enough
to
add foundation
to
the music, without
drawing attention
to
itselfas a separate source.
In
most
rooms, setting the
Low-Pass Frequency and Subwoofer Level controls
to
their mid positions will
provide an ideal blend with a Spinbase unit. However, do
not
hesitate
to
adjust
these controls
to
your preference,
or
to
compensate
for
room acoustics.
You
will
probably find yourselftweaking the settings quite a bit overthe first
few
hours,
or
even days, but eventually you will find settings
that
please you and further
adjustment will
not
be
necessary.
