THORENS TD 700 - Manual (Page 20)

Thorens record players are relatively insensitive when sub-
ject to foot-fall shocks or airborne resonance. 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 choose a sturdy piece
of furniture for placement and to avoid the proximity of the
record player to the loudspeakers.
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 for the sonic
properties of the record player if it is placed on such a shelf
or console.
The many possibilities of grounding an audio chain may
sometimes cause trouble in so far that a certain hum
can be heard through the speakers. This humming
noise becomes louder if the volume knob is turned
up. If there is audible hum we advise to re-check the
ground connection if it is securely fixed, or if perhaps
an alternative ground spot may remedy the problem.
In the event that causes for hum cannot be localised
and eventually eliminated please contact your Thorens
dealer for help.
When placing the record player onto its final position make
sure that it is a fair distance away from your other audio
devices, such as amplifier, receiver or CD player. This
measure is to avoid electro-magnetic interferences which
can yield a distorting effect in the sensitive pickup car-
tridge. This 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 devices.
