Possible problems Solution
No signal
No mains connection or fuse blown Check fuse, mains plugs and socket.
Power switch in OFF position Switch to “ON”.
No input signal
Check input connections, exchange RCA con-
nector, check source signal (is a different audio
component fed by the same source playing cor-
rectly?).
Level is too low
(analogue input) Source (mobile phone, mp3-player,
CD-player) has too low output level Check and increase level adjustment at the
source device.
Level is too low
(digital input) There is an attenuator at the source
side working Increase the volume of the digital output at your
source.
Sound is too quiet or
distorted Gain of the powered speaker is set
to a low level
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.
Even at low output
level of the source,
the sound pressure
level in the room is
too high
Gain of the powered speaker is set
to a high level
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.
The right channel can
be heard on the left
side and vice versa
(digital input)
Channel switch is switched to the
wrong positions. Select other channel on both speaker’s channel
switches.
Loud hum
Contact problems with connectors
(especially RCA or adapters for ex-
tensions) Check all connections; reduce the level at ELAC
speaker to min., the outer rings of the RCA
plugs may have to be readjusted.
Soft hum (during
pauses) Hum of source, ground loop with
RCA multi-connections
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.
Soft noise Source reproduces noise
Check of ELAC speaker for inherent noise: dis-
connect all inputs, switch power ON, normal set-
tings.
Now, with the ear near the speaker there may be
a soft noise, but nearly none at the listening
place.
