While locking to a source or changing some settings (e.g. Filter), the
microcontroller inside Elgar Plus is busy and will not respond to new
commands for a few seconds.

If the Mute fade-out rate is set to Mute-Slw, the unit may be unresponsive
for a few seconds while slow muting is in progress (see page 22)
•
Short mains supply drop-outs may cause the microcontroller to lock up.
Switch off the unit, wait 10 seconds then switch on again. If this does not
clear the fault, please contact your dealer.

The digital audio cable connecting Elgar Plus to the source may be
damaged, intermittent or of the wrong type. Some expensive cables are not
correctly designed for digital audio use. Try another cable.
