SP amplifier power saving
It is the pin which controls power
saving by the SP amplifier. At the time
of on in addition to the control in case
of automatic distinction function off,
too, power saving on by pin 50 has
priority over.
The entry impedance: About 137 kΩ
Standard bias source for EVR:
It is possible to use as GND (the DC
bias source) AC when connecting
external EVR. It is possible to attenuate
attenuate in the AC signal without
cutting a signal system in "C".
The output impedance:
Output pins for the HP amplifier:
It is output pins for the external
HP amplifier. The signal which was
adjusted in the volume in EVR can
be output by the low impedance.
The output impedance:
Equal to or less than about 10 Ω
Equal to or less than about 10 Ω
