No audible signal Blown mains fuse
Check/replace mains fuse
No audible signal No mains connection Check mains switch, plugs and
socket
No audible signal POWER switch in OFF position Switch POWER switch to AUTO or
ON
No audible signal No input signal Check input connections, replace
RCA cables, check signal source (is
a different audio component fed by
the same source playing correctly?)
Output level too low Output level from source is too low
(pre-amp, surround decoder)
Increase output level of pre-amp
(min 0.2 Volts), reduce power amp
again to compensate or: slightly
reduce gain for main (centre, effect)
speakers, to compensate increase
master volume
Max output slightly too
low (living-room)
Placement of subwoofer too ”open“ Place subwoofer in front of a wall or
a corner.
Uneven sound Unfavourable phase Play with phase control adjuster, if
no signal difference, move sub-
woofer by 0.5 – 2m and repeat.
Sound during loud tracks
somewhat distorted es-
pecially loud buzzing
noises in surround mode
Centre or effect speakers are being
overdriven by their power amps
Reduce centre or effect level at sur-
round decoder; use centre mode
‘normal’
Loud hum Contact problems with RCA connec-
tor (adapter for extensions)
Check all connections; reduce the
level on ELAC sub to -30dB; the
outer rings of the RCA plugs may
have to be adjusted.
Soft hum (during pauses)
Hum from source, ground loop with
RCA multi-connections
Check the ELAC sub for inherent
hum: switch POWER to OFF, dis-
connect all inputs, switch to ON,
normal settings.
Now, with the ear near the speaker
there may be a slight hum, but none
at the listening position.
