Connect the turntable to the line input of
your pre amp _OR_ switch the internal
phono pre amp to "THRU".
Swap the two RCA plugs (left and right
channel) which are plugged into the
turntable's RCA jacks.
Check all connections; for acoustical
check relating major problems reduce
the amp's volume level to minimum.
Possibly the RCA plugs ground rings
should be readjusted.
In certain cases, it makes sense to
connect the metal parts of the turntable
to signal ground of the (phono-) preamp.
On the rear side of the turntable there's
an earthing screw for this purpose.
Please use the wire attached to the
included RCA cables for this.
Check which speed should be chosen
for playing the current record. There
are also records on the market which
have the same diameter as an LP (30
cm) but must be played at 45 rpm (e.g.
maxi singles). On the other hand, there
are also records in single format (17 cm)
which should be played at 33 ⅓ rpm (so
called "EPs").
