output level
Check and increase level adjustment at the

„open“
Place subwoofer in front of a wall or a corner.
Loud hum Contact problems with RCA con-
nector (adapter for extensions) Check all connections; reduce the level an ELAC
sub to -30dB; the outer rings of the RCA plugs
may have to be readjusted.
Soft hum (during pauses)
Hum for source, ground loop with
RCA multi-connections Check of ELAC sub for inherent hum: switch
MODE to OFF, disconnect all inputs, switch to
ON, normal settings.
Now, with the ear near the speaker there may be
a soft hum, but none at the listening place.
