Sounds like there is a short circuit on speaker B. The amp is simply protecting itself by shutting down. Have you tried a different cable between the amp and speaker B? If it still happens with different cables, it's likely the speaker needs repair.

ARCAM av receiver says Fault 01 detected .. DC
Hello
I recently purchased two Martin Logan EFX as my left and right channel speakers for living room. I am currently having an issue where only one of two speaker works properly with the AV receiver.
1- Speaker A works with receiver on either front right or front left.
2- Speaker A and B when connected together to right and left or vice versa, the AV receiver trips and goes into standby mode. My ARCAM av receiver says Fault 01 detected .. DC
3 - Speaker B when connected with receiver on either front right or front left, i get the same issue and receiver goes into standby mode.
So what can i do to fix this faulty EFX speaker? Is it the speaker or the receiver issue? Should i run the Dirac?
PS - All cablings are correct. RED is going in RED and BLACK in Black on both ends.

Thanks for the response. So what happened was that i by mistake connected RED with BLACK on receiver side. Do you think if that would have caused a short circuit to that speaker?Sounds like there is a short circuit on speaker B. The amp is simply protecting itself by shutting down.

The only thing that will happen if you connect the speaker cable in reverse is that the speaker will be out of phase, remember it is AC voltage and not DC voltage going from the amplifier to the speaker.Thanks for the response.

Are there any bi-amp bridges on the speakers that are installed the wrong way around?
If you have a multimeter, try and measure the resistance between red and black on the speaker with no speaker cable connected. If it is reporting 0 then it is a short circuit inside the speaker.
Thank you. I will do the same.The only thing that will happen if you connect the speaker cable in reverse is that the speaker will be out of phase, remember it is AC voltage and not DC voltage going from the amplifier to the speaker.

One more thing, the faulty speaker does play but the volume is very low compared to the other channel. If the speaker is truly shorted, would there be any sound coming from it? Whenever i increase the volume on the faulty speaker (more than 55 on Arcam) the receiver trip when connected to that speaker.Thank you. I will do the same.
It could be something with either one voice coil or the crossover that is faulty but not enough to cause a right out short circuit.One more thing, the faulty speaker does play but the volume is very low compared to the other channel.

Once you have the multimeter you can measure and compare both the speakers. At least you have a working reference to compare all measurements with.
