Thorens turntables are relatively resistant to vibration.
However, vibration can have adverse effects on any
turntable, particularly if a high-quality pick-up cartridge
is used. You should therefore place the turntable on a
sturdy piece of furniture, ideally at some distance from
the loudspeakers.
older houses with beam floors, however, this may not be
enough to properly isolate the turntable from vibrations.
In this case we recommend placing the turntable on a
wall shelf that is attached to a supporting wall.
When siting the turntable, make sure that it is at a rea-
sonable distance from any existing electronic equip-
ment
(such as amplifiers, receivers or CD players) so
as to avoid electromagnetic interference in the pick-up
cartridge, which could cause a hum in the signal. The
same applies to the cable connecting the turntable to
the amplifier.
You can detect and eliminate electromagnetic inter-
ference by changing the position of the turntable with
respect to other pieces of equipment.
