The power supplies for the analogue and the digital circuits are strictly separated

The power supply unit has three separate power supplies on board One power sup-
ply is dedicated to the analogue section of the phono preamplifier 750/751 exclu-
sively another power supply takes care of the relais and the controller unit In
standby operation still another power supply is used
The power supply for the analogue sections guarantees optimal condition for the op-
eration of the phono preamplifier 750/751 It has the following features:
- Extremely stable on irrespective of the load with a maximal deviation for the
+/- 15V supply voltage of 5mV (load regulation)
- Lowest influence to changes in the mains supply voltage (line regulation)
- Nearly not measurable noise of the supply voltage (AC < 2µV
RMS
)
- High current supply for short load changes of max 12A
A multi stage filter network protects the audio circuits from potential interferences
with noise present in the mains
