HE 60
HEV 70
The HEV 70 amplifier has been developed
especially for use with the HE 60. As a high
voltage/semi-conductor amplifier it supplies
the polarisation voltage needed for the
electrostatic headphone HE 60 and amplifies
the incoming signal.
Connections and operating elements
2-channel-switch for volume control (high
qualitiy ALPS potentiometer)
Volume control
volume control button right
volume control button left
The control buttons
joined by a sliding clutch, this way
they are operating simultaneously.
Channel differences of a sound source
can be compensated by holding tight
the control button
correction at the same time with the
controll button
Operating and
overmodulation indication
This LED is emitting green light when
the amplifier is operating.
If the LED begins to emit
sometimes red light the amplifier is
overmodulated. Reduce the volume!
On/off switch
Connection socket for HE 60. This
socket supplies the signal and
polarization voltage for the headphone.
Power supply, connection for the
cable of the power supply unit NT 20.
