Setup and preparation the drive for use:
The assembly step by step:
1. Place the housing (A) at the space, where it should be used.
2. The stands of the drive are adjustable in height. Just turn the corresponding
stand clock/counterclock wise, to adjust for a non-flat surface.
3. Unlock the 3 integrated transport locks as follows:
Attention: The platter can only be installed, when the transport locks are
inactive!
4. Place Platter (C) carefully on motor axle and motor platter. The platter is not
fixed with screws. It lies just with its own weight on the motor platter.
Attention: The complete drive must not be moved with the platter
installed! The heavy platter can destroy the motor bearing in case of
shock during transport.
5. Place platter mat (D) on to the platter.
6. For installing a tonearm, refer to instructions of the tonearm manufacturer. As
an option, langer audio offers adaptor plates (G) for a huge variety of tonearm
brands. There are also raw adaptor plates available for adapting exotic
tonearm types.

7. The signal cables of the tonearm can be routed through a big hole in the
bottom plate of the turntable (refer picture). Usually, there is a ground cable
installed at the tonearm. It must be connected to the turntable chassis ground,
to avoid hum noise. There is a connection point for this cable at the chassis
bottom plate (refer picture).
8. Normally, there is also a ground connection needed between amplifier and
turntable. This is to avoid hum noise. Therefore, use cable (E) and connect it
to the ground point at the backside of the turntable (refer picture below). The
other end of the cable must be connected to the amplifier’s ground clamp.
9. For cartridge installation, please refer the manual of your tonearm
manufacturer.
10. Now you can connect your turntable to mains. Please use the power cable (F)
and connect it with the plug at the backside of your turntable (refer picture
below).
Attention!
Do only use a power cable in perfect
condition, to prevent electric shock
or fire hazard.
