Martin Logan Aerius problem


Hi,

There is almost no sound coming from the electroststic panels on my speaker. The sound can only just be heard by placing your ear next to the panel and then it sounds more like a kazoo then a speaker. There is almost no difference when the AC is disconnected and if the input is connected to the electroststic posts only the sound is as described above. Has anyone elese had a similar problem and is there a simple fix.

I have checked that the power is being supplied to the speakers and that the internal fuse is live.

Regards

You could have a bad panel -- but did you check the continuity of the internal fuse with a meter or simply look at it? I've had blown fuses that didn't look blown...
Is this from a single speaker in which case the problem likely is with the speaker itself, or from both speakers, which implies the problem could be with some other part of your system?
I'm an Aerius owner but you must enunciate your problem. Geeez. What the hell are electrostatic posts?
Hi All,

Thanks for your interest and help. To answer your questions:

Plato: I checked the continuity of the fuse and it was OK.

Rmrobinson1957: The problem is from both of the speakers. They were connected to a quad 33/303 pre/power amp and I always thought that the poor sound was because the amp under powered (45 WPC)and could not drive the electrstatic panels. I have just upgraded to a Primare A30.1 and the complete lack of mid range and treble was unchanged with the upgrade.

willhitx: Sorry for the confusion. I am not sure of the correct terminology. by the elctrostatic posts I am referring to the speaker input connections to the electrostatic panel.

I have also checked that the AC supply was reaching the internals (it is) but when doing this I noticed that there is a red LED on the printed circuit board which illiminates for about 30 seconds and then goes out. I am not sure if this is normal. I have had other feedback which suggests that the panels are only good for about 8 years and then need replacing and so far this seems to be the most likely cause. I have lodged a call to ML service department for their advise.

Did you vacuum the panels? Dust accumulated in the holes and on the panels will cause this to happen to some extent. Be careful and use the brush attachment when doing so.
