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 and are 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 and realizing the 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.
