Martin Logan Aerius problem

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.

Regards

Paul

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.

Mlogan,

The red LED lights up when the circutry detects an input
signal. It sounds like you've got a bad connection or a
blown component somewhere.

The red LED should light up and stay lit if the speaker is
receiving a signal of sufficient level.
