Solution
Check fuse, mains plugs and socket.
Switch to "ON".
Check input connections, exchange RCA con-
nector, check source signal (is a different audio
component fed by the same source playing cor-
rectly?).
Check and increase level adjustment at the
source device.
Increase the volume of the digital output at your
source.
Reduce the level of the source to appr. 50%,
switch the gain control switch of the powered
speaker to a more sensitive position until a
comfortable volume is reproduced within the
room.
Reduce the gain of the powered speaker to min-
imum; increase the output level of the signal
source to appr. 50%; now increase the gain of
the powered speaker until a comfortable volume
is reproduced within the room.
Select other channel on both speaker's channel
switches.
Check all connections; reduce the level at ELAC
speaker to min., the outer rings of the RCA
plugs may have to be readjusted.
Check of ELAC speaker for inherent hum: dis-
connect all inputs, switch power ON, normal set-
tings.
Now, with the ear near the speaker there may
be a soft hum, but none at the listening place.
