Question about Sony STR-D565 Receiver
That model of receiver goes into protect mode when there is really
resistance or a short on your speakers/wires. It does it to protect the
final drivers in your amp. Does it do the same thing with all of your
speakers disconnected? If it doesn't then you might have a problem with
one of your speakers or wires. Check your wires for shorts in them
first. That may be the only problem. That model is designed for 8 ohm
speakers, but you can go down two 6 ohms safely. I have a STR -D865 that
has been running 6 ohm speakers safely for almost 3 years now. A way to
check your speakers out is to take an ohm-meter across the terminals on
them(with the receiver unhooked). They should read anywhere between 8
and 4 ohms. Check with the manual on your speakers to see if they
correspond. If the resistance is really low, you may have a short in
that speaker. it is also possible that if they are 4 ohm speakers, you
could have damaged the drivers in your receiver. I know the model above
mine, (the 965) has a 4-8 ohm speaker selection switch on the back. The
lower models were not designed to run 4 ohm speakers. Hopefully this has
been of some help.
