THORENS TD 550 - Manual (Page 31)

Take the supplied ground lead and connect the ground
post (8) at the rear panel with the ground post on your
preamplifier/amplifier or separate phono-preamplifier.
When placing your record player onto its final position
make sure it is a fair distance away from other audio devic-
es (e.g. amplifiers, receives or CD players). This measure
is to avoid electro-magnetic interferences which can yield
a distorting effect in the sensitive pickup cartridge which
may be audible as hum during playback.
Electro-magnetic interferences however can be dis-
closed and eliminated by simply changing the position
of the record player with respect to the other audio
components.
Thorens record players are relatively insensitive when sub-
ject to foot-fall shocks or airborne vibrations. Neverthe-
less, a general problem remains when it comes to playing
back vinyl records with a high-quality pickup cartridge. It is
therefore highly recommended to go for a sturdy piece of
furniture or rack for placement, whereby a close proximity
of the record player to the loudspeakers is to be avoided.
Under certain circumstances all these precautions may not
be good enough in older houses with wooden floor con-
struction. Here, in most cases a solid shelf firmly mounted
to a supporting wall can be very beneficial to the sonic
properties of the record player if it is placed on such a shelf
or console.
