Owner's Manual
Variable
audio
output
HD4
includes a variable full-range
preamp
audio
output
so you can
connect
a
subwoofer
or
another
music sytem. The
HD4
output
is
adjustable so
the
volume
level can be
controlled
from
the
HD4
volume
control
or
your
phone, computer,
or
tablet.
You
can also wirelessly stream music wirelessly from
HD4
to
other
systems
around
your
house by
connecting
the
Audioengine
W3
wireless
adapter
to
the
audio
output.
The
HD4
system includes built-in
power
amplifiers so
do
not
connect
the
HD4
speaker
terminals
directly
to
the
speaker
outputs
of
a stereo receiver
or
power
amplifier
. Instead use
the
preamp
output
of
your
stereo receiver
connected
to
one
of
the
audio
inputs
of
the
HD4
.
Break-in
period
Your speakers
will
sound great
out
of
the
box and
will
get better over time.
No need
to
do
anything
else
but
listen
to
them,
however, we
do
recom-
mend
that
you give
them
at
least 40
to
50 hours break in ti me before
doing
any critical listening.
Cleaning
We
don't
recommend
using any solvents
or
cleaners. Just
wipe
down
the
cabinets
with
a soft,
dry
cloth
.
