A722 output connector

Please note that the polarity of the DIN speaker output sockets is reversed
compared to the standard. Common ground is on the round pins.

This may be a problem if you use your standard selfmade lab adaptors
and connect the outputs to a common ground input i. e. a scope input
for example. The same may happen using active subwoofers with
common ground.

The amp channels will usually not fail if driven with the same (mono)
signal but show erroneus behaviour.
