humm…interesting…

The document I found on the internet mentions on page 15 the impedance of 5.7 Ohm for the midrange and 3.0 Ohm for the tweeter. Furthermore, just to record here, 3.1 Ohm for the lower bass and 5.0 for the upper bass. NTC sensor 470k Ohm @ 25oC.

Anyway, i just found out that the problem resides in my Beosystem 3.

I changed the powerlink port and the problem was solved. I don’t understand why…

Are both speakers set to the same line input voltages, 0-2V RMS or 2-4V RMS?

I had the same problem here with one of my BL5.

Solved it by “regluing” the top sensor in place. It was too sensitive to the touch and when the ambient temperature was warmer, it was activating by itself due to thermal expansion of the aluminum plate.

Just open the top plate (lift and twist), heat it with a hair dryer and lose the sensor. Then let it cool down and put the sensor back.

Two years already and the problem never came back here…

Anyone knows if the IC304 is the responsible for storing calibration data?

[DanteM]

Flashes green only? Looks like it didn’t store the calibration parameters.

Could be a fault in a memory chip in the chassi.

Have you checked the distance settings of your speakers?

[DanteM]

Yes, but my point here is about using other speakers to improve the sound coming from a different speaker.

I think Geoff mention something like this in the past for B&O, but Dirac launched it first?

[DanteM]

That’s a great idea! I didn’t think of that before!

I’ve easy access to a guy who paints with powder. Will check on that.

Thanks for the tip!

After the cleaning…

Regarding Atmos speakers, can’t we use the Beosound Shape on the ceiling?

I’m using a bluetooth receiver with RCA out to connect my Lg to the BL8000.

My TV only have optical and hdmi out, hence the solution.

I had the same problem with my BL5 some years ago. First I thought that the problem was the 96kHz spdif signal, as the BL5 has a 88.2kHz limit written in the manual.

One speaker was fine but the other sounded weird in the tweeter. I found out that when daising chaining the spdif signal, the output from one speaker to the second one is limited to 44.1kHz, even when the original signal in the first speaker is higher.

However, looks like someone updated the eletronics to allow 96kHz input, but forgot to mention that in the manual.

 

In the end, i found out that the distortion was from bad cable. I was using ordinary analog audio cable, which has good shielding up to 50 kHz signal. As I was feeding 96 kHz signal, lots of distortion came up. The second speaker didn’t show any distortion because the signal was reduced to 48kHz.

So I changed my spdif cable to a digital one and then everything was great.

 

Steve from Sounds Heavenly can help you with that.

Gluing some basstraps on the corners and praying for wife to allow them…

Does anyone knows how far the room compensation of the theater goes?

Does it correct all channels when vintage Beolabs are connected to it or just its own sound?

the compensation is done just in frequency or in time domain as well?
