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.

the optical input.

Some digital audio formats (such as surround

sound) are incompatible with the MRA system.
