(9). Otherwise it may be defective.
Unit fuse or amplifier is defective.
The audio source currently selected at the
preamplifer is giving no signal.
The output of the source device is not connec-
ted or is wrongly connected e.g. not connec-
ted to the selected input channel terminal of
the preamplifier.
