    Layout Layout The preamplifier 720 is realised as asymmetrical dual mono circuit. Left and right audio channels (incl. phono mc stage) each have identical circuit boards. Resulting in a channel separation of >105 dB, prerequisite for a three dimensional spatial re- production.

  • Page 11: Output Stage

    Power supply Power supply The preamplifier 720 has two separate power supply units, one for the supply of the audio section, another for the supply of the digital circuits. The stringent separation of the power supply units is amended with a multi stage filter network. Interference between digital and analogue circuits is thus minimised.

    > 15 mV is detected a high quality capacitor is switched into the signal path for op- timal protection of the preamplifier soulution 720. The display shows the symbol for the capacitor (╪). If the DC-offset has disappeared for at least 15 seconds the ca- pacitor is switched out of the signal path.

  • Page 21 The current input remains active until the new input has been selected and the In- put-knob was not turned for ca. 3 sec. All other inputs remain completely disconnected from the preamplifier 720. Signal and ground are (dis)connected by top class relays. Hum noise originating from even- tual equalising currents between connected audio components is thus effectively eliminated.
