Specifications
In
order
to
determine
the
polarity
of
your system, you
IJI1St
find
out
which
pieces
in
your system
invert
the
signal,
and
wch
ones do
not.
This information
is
sanetimes given
in
owners manuals.
Othemse,
you can
contact
your
dealer
or
the
manufacturer,
or
look
in
AUDIO
Magazine's Annual Equipnent
Directory
(in
each
year's
October
issue),
which
lists
the
inversion
status
of
sane
units.
Once
you have
this
information,
its
easy
to
determine
the
polarity
of
your system
and
correct
it,
if
necessary,
by
reversing
the
connections
of
the
sPeaker
wires
to
each Angelus.
Make
a
list
of
nunbers
that
correspond
to
each
piece
of
equipnent
in
your
system,
including
everything
from
the
source
to
the
speaker
outputs
of
your
receiver
or
power
amplifier.
If
the
unit
inverts,
give
it
a
value
of
1;
if
it
does
not,
give
it
a
value
of
O.
For
VCRs
and (])
players,
it
is
probably
safe
to
assune
that
they do
not
invert.
Now
add up
all
the
mmbers.
If
the
result
is
an
even
nunber
or
0,
your system
is
positive
polarity,
and no change
is
required.
If
the
result
is
an odd
nmber,
you should
reverse
the connections
to
each Angelus
at
its
input
terminals.
On
Tone
Controls,
Loudness Switches,
and
Runble
Filters
The
so-called
'loudness'
control
found
on
receivers
(and
sane preamps)
is
intended
to
make
the
perceived
tonal
balance
of
lJI1Sic
sound
more
natural
when
it
is
played
at
low
volme
levels.
When
engaged,
the
10ldness
control
boosts
the
extreme
bass
and
trebles.
When
playing
your system
at
mediun
to
high
volune
levels,
this
can gobble up a
lot
of
amplifier
power
and
place
unnecessary
demands
on
the
excursion
of
the
Angelus' woofer,
so
MAKE
SURE
'!HE
LOUDNESS
OONTROL
IS
SWlTOiED
OFF.
If
you
are:
>
playing
a
record
that
is
badly warped,
>
playing
your system
VERY
loud
with
a
record
as
the
source,
or
>
boosting
the
bass
a bunch
with
your
bass
tone
control,
then you should
consider
engaging
the
rmble
filter
on your preamp/
receiver
if
it
has
one. Otherwise,
it
should
be
left
off.
