SOURCE: On a aiphone C-ML, when

The system uses slight different frequencies for receiving and emitting - most likely you were unlucky enough to get a unit with the receiver frequency that has a mirror one occupied by a legit public station who doesn't filter it's harmonics correctly.
The dealer is correct, a simple LC filter on the receiver will eliminate the crosstalk and the radio station should fix it for you - contact them , explain the situation and ask them to either filter their emitter better of fix your unit.

Can I connect camera and monitor to existing aiphone Vc-6M intercom?


Aiphone intercom systems are very restricted in what you can and cannot connect. Also the type of functionality you require is determined by the master station that you have. With apartment system VC6M you will be able to configure very specific modules which can be viewed at this site and this is not much.

As the description suggests it is only meant to be a cost effective audio unit. (Video is available in apartment mode with the GT system)

Why aren't you looking at the sub for the reason? It may have the crossover set too high.

If the sub is loud enough during level setting, look at receiver settings, otherwise it's the sub amp.

MEX-BT5700U, no sound in speakers in CD source, tuner source OK.


What many people do on this model is connect the remotes wires improperly. Use the solid blue wire for the amp and the blue with white stripe for the connection to the car.

Bought a used Martin Logan Dynamo subwoofer a couple days ago and have a very loud hum when the ac cord is plugged in, even if the speaker is not connected to an audio source. The "hum" can be heard in any...


Neither the amp or the sub have grounded power cords.

I have discovered the ML Dynamo takes about 30 minutes to switch to standby in auto mode.

With speaker level inputs connected to the Onkyo A807 amp, both units powered from the same wall outlet, Dynamo sub on Auto, the sub hums for about half an hour after the Onkyo is switched off, then the sub goes quiet. Not so good.

I connected a bonding wire between the two units on 3_7_09. If I smoked some old audio gear I could just look at that as an opportunity, right?

Works fine. Now I have the ML powered from the wall and working normally.

Sound shuts off, sub still works


That is a common problem with this radio, for it can not go to loud without going down in volume or shutting down.

It sounds like your sub may have died ,get hold of a mulitimeter and check the impedance it should be 2 or 4 oms depending on the sub.
