Multiconverter DU 937
This external power supply for EMT 930 and EMT 927
enlarges the application field and offers an improvement in sound under very
quiet listening conditions.
Extended
applications:
 |
Vari-Speed |
For the first
time since we have EMT 930 and EMT 927 it is possible to change the speed by
using vari-speed. With the Multiconverter DU 937 it is possible to change the
speed +/- 10 %. This is very important if you play records which have not been
cutted with the standard speeds, especially for persons with very sensible
ears.
Some
schelllack-records need more than 78 rev/min. Now they can be reproduced by
EMT 930 and EMT 927.
|
Feltbrake
compensation |
It is well known
that EMT 930 and EMT 927 use a feltbrake to adjust the right speed. This
feltbrake generates a constant noise which can disturb the music reproduction
under very quiet listening conditions. Now the Multiconverter DU 937 allows to
adjust the correct speed without the feltbrake for the first time, the
disturbing noise has disappeared.
|
Operation with
50 Hertz or 60 Hertz |
The output
voltage of the Multiconverter DU 937 can be adjusted to 50 or to 60 Hz.
Connection of the
Multiconverters DU 937:
The Multiconverter
DU 937 is connected as a power supply between the turntable and mains.
More advantages:
|
An extremely
low-distortion output voltage guarantees a smooth running of the motors of EMT
930 and EMT 927. |
|
By using the
Multiconverter DU 937 you are independant of variations of the mains voltage
and frequency. |
