The SPEAKERS A and B switches allow you to
switch between the speakers connected to the A
SPEAKERS
terminals or the
B SPEAKERS
termi-
nals on the rear panel of the Akai amplifier.
If only one set of speakers is connected to the rear
SPEAKERS terminals, simply set the other switch
to OFF. When listening through headphones, set
both speaker switches to OFF.
Protection circuit
_
When the Akai amplifier is turned on, no signal will
be output to the speakers for a few seconds. The
power indicator will first light up red for a few
seconds, then change to green when the Akai
amplifier has gone into normal operation mode.
This is due to the protection circuit which prevents
output of noise when the Akai amplifier is turned
on.
The protection circuit also functions during play-
back to protect the speakers from overloading, and
to protect the circuit from damages. When speak-
ers with less than rated impedance are used, the
protection circuit will short-circuit the + and —,
speaker cords.
When
the protection
circuit
is engaged,
the
POWER
indicator will change from green to red
and output signals will be cut automatically.
Should the sound be cut during playback and the
power indicator changes from green to red:
1
Turn off the Akai amplifier.
2
Check for and correct the cause.
3
Turn on the Akai amplifier.
