6 Troubleshooting
Symptom Possible Explanation
There is no sound after switching
the Amplifier on (sound worked
previously).
The volume may have been set to minimum,
or the Amplifier may have been Muted (on a
Desktop Amplifier) before the Amplifier was
switched off.
The default volume, bass or treble
settings have changed (when
switching the Amplifier on).
If a power failure occurs when the Amplifier is
on, the volume, bass and treble settings are
saved and become the new defaults.
An Amplifier switches off,
particularly when the volume is
loud.
If insufficient current is available for the
Amplifier, it will switch itself off.
This may occur if the Amplifier receives its
power from a Matrix Switcher.
Cannot hear any sound when
using the optical input
Some digital audio formats (such as surround
sound) are incompatible with the MRA
system.
