SETTING
UP
THE
DDL
204
To
achieve
the
best
results
with
the
DDL
204,
the
unit
must
be
connected
properly.
To
start
the
unit
up,
connect
the
enclosed
mains
connection
cable
with
the
DDL
204's
mains
socket
and
your
mains
outlet.
In
order
to
avoid
temperature
problems
the
unit
should
be
ventilated
sufficiently
and
not
operated
at
ambient
temperatures
above
40°C.
Before
you
switch
on
the
DDL
204,
all
connections
should
be
made
according
to
your
required
configuration
and
wiring.
•
Always
use
well-screened
audio
cables.
•
To
avoid
high
frequency
losses,
the
feeding
lines,
especially
to
the
inputs,
should
not
exceed
10
m.
•
Do
not
position
the
unit
directly
on
or
under
a
power
amplifier,
TV
monitor
or
the
like,
as
the
leakage
field
of
the
transformers
in
such
devices
could
induce
hum
into
the
electronic
circuits
of
the
DDL
204.
