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.
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.
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
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.
- 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
voltage 100-230 V
input frequency 50-60 Hz
output voltage adjustable from 100 to 230 V
output frequency adjustable 50 or 60 Hz
frequency in vari-speed +/- 10%
dimensions 36 x 10 x 37 cm
