PLACEMENT OF THE TURNTABLE

Placement of the turntable

The suspended Sub chassis

The

Thorens TD 1600

and

TD 1601

are equipped with

a spring-mounted sub chassis that neutralises mechani-

cal disturbances from the ground and resonances of the

drive motor.
This sub chassis consists of a specially shaped MDF

board, which stands on three damped cone springs,

which are bolted to the bottom plate of the turntable.

This principle of spring and damper is best compared

with a suspension in the car, here is a spring combined

with a shock absorber to prevent an uncontrolled swin-

ging. Platter bearing and tone arm board are mounted

on the sub chassis, while the motor and cover plate are

connected to the bottom or the frame. Thus, the moving

parts are isolated from the solid.
The sub chassis itself must be tuned to the particular

turntable, the spring tension is regulated so that it vibra-

tes evenly and as if piston-like with a stimulation without

breaking laterally and the height must be adjusted so

that when the device is aligned horizontally, turntable

and tone arm board are parallel to the fixed top board

and the platter. Platter must not touch top board in ope-

ration.

The correct settings are already made in the factory and

normally must not be changed by the user of the turn-

table. If something has to be readjusted, the necessary

adjustment screws are accessible from the underside of

the turntable. A qualified retailer or our service specialist

will be happy to help if a readjustment is required later.

Placement

Turntables with sub chassis require a different kind of

installation than record players with a fixed chassis or

so-called mass drives, which prefer a stable base with

high mass. However, sub chassis drives like Thorens

TD 1600

and

TD 1601

can be placed on a light but sta-

ble surface. A light, stable table, with the plate and legs

firmly connected, fits very well, for example.
It is important that the turntable is in the balance. For

this it is possible to screw the feet up or down.
