Battery life expectancy

The batteries used in the ASR Power supply are completely sealed Gel lead acid Types.
Like all batteries they lose their capacity of storing electrical power over the years.
When the ASR Basis is able to play only one day without recharging, the batteries should
be replaced. To get best results, please replace the batteries after 5-7 years of use.
The batteries can be exchange easily at your dealership.
To lengthen the lifetime of the batteries please do not use the Basis with the ON/OFF-
selector to the "Batt" Position for longer than one day.
Otherwise the batteries may get completely discharged !
The ON/OFF switch can stay in "Line" position. The ON/OFF switch in "Auto" position can
also be used all the time, when you listen to records a few hours per day and there is time for
recharging when the unit is not being used.
Please avoid playing records continuously in Auto Mode, without letting the unit time to charge.
This shortens the life expectancy of the batteries
One hour of charging is equivalent to three hours of playing music.
If however, the unit is left in "Auto" position all the time then you don't need to do anything as it
relates to charging the battery unit.
When you have disconnected the Basis from AC power network cause you are not using it, please
charge the Battery unit at least for one day every month.

7.0 The
6.1 Function of the main unit
The ASR Basis Exclusive is an Phono-Preamplifier for MC and MM. The input stage
is fully balanced and amplifies the input signal linear. Gain, input resistance and input capacity
can be easily adjusted. Either unbalanced mode can be chosen by grounding the negative input.
The signal then passes a passive high frequency RIAA filter.
The low frequency cut OFF is switchable. The following amplifier achieves an active RIAA
equalisation. With its very low output impedance it drives the unbalanced output directly.
The balanced output is equipped with an additionally converter/driver circuit.
The ASR Basis Exclusive has a double-sided layer board with two very thick 105 µ
copper-lead-layers. In the signal path only Polypropylen and Polystyren capacitors are used.
Additional foil capacitors are used to buffer the operational voltage.
The main unit has more than 860,000 µF capacitors.
