Cleaning
Help!
Turn off the subwoofer at the power switch before cleaning.
The cabinet of the M2500 is finished with veneer and can be
wiped clean with a damp cloth.
The heatsink is anodised and painted aluminium which can be
dusted with a paint brush if necessary.
Do not use abrasive cleaners on any part of the M2500.
No Sound.
Check the AC power supply to the M2500. The green light on
the front should be lit.
Check the AC supply to the other units in the system.
Check that the correct source is selected and that the source
itself is producing music.
Check that the interconnections are made to the correct
sockets.
The loudspeaker outputs are protected by a fuse. In the
unlikely event of a fault condition, this will blow to protect the
drive units from damage.
Unit goes silent when played hard.
M2500 has a temperature sensing system on board which
prevents overheating of the electronics. The sound will continue
when the loudspeaker has cooled.
Too little or too much bass when listening.
Have you calibrated the system properly? See the section on
Sensitivity Setting.
Bass sound phasey or hollow.
Your subwoofer may be out of phase with the main system. See
the section on Phase Correction.
Bass sounds boomy when certain notes are played.
Systems containing subwoofers can produce very high levels of
bass which may cause fixtures in a room to rattle and excite
'boomy' standing wave resonances due to the shape of the room.
Correct speaker positioning can help minimise these problems. Try
adjusting the position of the subwoofer. If the subwoofer is close
to a corner, move it further out from the corner if possible.
