and is set
at

Cau_
tion:
For safety reasons,
the
mains voltage must only
be conver_
ted in
a specialist workshop. please connect
the
speakers
and
program sources (turntable

(19i.
All
speakers with
an impedance
of
g
-
j6
Ohm can be
used.
The cross section of each wire of
the speaker connecting
cables
should be:
at
least 0.5
mm2
up to
a
length
of 5
m, at least
O]75
mm,
up
to
a
length
of

more than 20
m.
ln order to ensure phase-synchronized connection (otherwise the
stereo effect will
be lost), the terminals
on
the speakers
and on
the
receiver
must always be
connected
to
the corresponding
terminars
with the same colors.
The
red terminal must be linked to the connection
on the speaker
