Klas, I guess that they initially planned to implement a standard 48 V
phantom power supply. Obviously they faced some technical problems in the
electronic circuit due to the low battery voltage and the limited space
available in the small housing. A standard phantom power supply must be abl=
e
to provide 48V at a current of 10mA for each channel. The required DC/DC
converter circuit would theoretically draw a current of at least 200mA out
of a 4.8V battery. That's a pretty high current for the small-sized battery
and the switching transistors that must perform the voltage conversion (hig=
h
currents lead to unavoidable voltage drops).
Regards,
Raimund
