The ADN-N is a high quality selectable Moving magnet/Moving coil phono preamp to allow use of a record deck into a normal high level amplifier input. It is powered by a separate toroidal power transformer in order to keep the audio circuit as quit as possible.
It has been designed to cope with both Moving Magnet and Moving Coil type cartridges. Both gain and load are selectable via dedicated switches accessible from the back of the panel.
The ADN-N chassis is made of aluminium with a front panel of 8mm.
The whole circuit uses only discrete components. Passive RIAA construction.
