resistor (2.2 MO) and thus , draws no appreciable current. The expiration date
printed on the battery generally coincides with the need to replace the batteries.
Each capacitor position is actually made up of two capacitors connected in
series. The battery voltage is applied to the center connection of the two
capacitors. This produces a voltage potential between the two plates within the
capacitor. When the two parts are taken as a whole, there is no DC voltage that
appears across them, but individually they are each bias ed. The sonic result of
the biasing yields an increase in detail, increased smoothness and considerably
more natural decay of sounds within the music.
