el manual dice esto:
If the core wires touch the rear panel and the screws
etc., or the ± sides touch each other, the protection
circuit will be activated and the power indicator will
flash red at intervals of 0.5 secs.
If the protection circuit is activated, the speaker
output is isolated, and the power supply goes to
the standby state. If the power supply is turned off,
after the power supply cord is withdrawn, please
confirm that speaker cable and input cable are
connected.
Also, if replaying large sound levels by using
a speaker having an impedance less than that
specified (eg, 4 Ω/ohms), the temperature will rise,
and the protection circuit might be activated. The
power supply will go into the standby state, and the
power indicator will flash red at 2 second intervals.
In this case, please switch off the power supply,
and wait until the AVR-1910 has cooled down, and
the surrounding ventilation is good
