GROUND LIFT switch
If your system only takes audio sources from CD or DVD,
set this switch to ‘
GROUND ’. In more complex setups which
involve satellite inputs or radio aerials, grounding the unit may
actually increase the level of background hum or buzz in the
loudspeakers, in which case set the switch to ‘
GROUND LIFT ’.
REMOTE CONTROL INPUT
This input is connected to the output of an infrared receiver. The
remote control input is usually used in custom installations. Ask
your dealer or custom installer for further details.
