Protection circuit
When the Akai amplifier is turned on, no signal will
be output to the speakers for several seconds. 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. Therefore, should the sound be cut
during playback:
1 Turn off the Akai amplifier.
2 Check for and correct the cause.
3 Turnon the Akai amplifier.
