Thanks for the list.

I have a BV7-40 mk. IV type 9440, but local B&O service center told my that I need the hardware update. Is that true?
I am confused, and must say that I tend to believe more in what I read here than what I am told in stores or by a repair man.

Any one who knows this, or should I just pay the 700 €? 🙂

I am no expert, but based on what I have read, and what my dealer told me when I was considering adding AST to our MKIII, your TV, being a MKIV should only need a software update.

Thanks. I a just wondering, that my TV being one of the first mkIVs to leave the factory, has been shipped without the new sound board.

I will try to have another talk with my dealer in the coming week.

I am about to upgrade my BV9/BS3 with the new Digital Surround Module and latest s/w build. Can anybody answer if the attached loadspeakers to the BS3 can simply be "daisy chained" in a single "loop" from the BS3 or if they need to be at least Right and Left seperated in two "loops".

Hope that the question is understandable.

Here in the US only two can be daisy chained, just as you say, front  left and right, rear left and right, surround left and right.

Hi Geoff,

Is there value in AST if you have a simple BV7-40 and BL7.2 set up?

Thanks for your advice.

Stephen

Hope you do not not mind somebody else giving you an answer. Obviously the best answer would be from Geoff, but the instruction guide for AST on the B and O web page mentions that it should not be used if there are only a "few" speakers.

Hi Stephen,

If you have only the BL7.2 and no other loudspeakers, then you will not be able to turn AST on. AST requires that you have at least 3 loudspeakers connected in order to enable it (it will be greyed out in the menus with fewer than 3 loudspeakers). Also, I would say that it's probably not worth turning on without at least 4 loudspeakers - more is always better ;-)

To be clear, a BL7.2 is considered by AST to be 2 loudspeakers. The exception to this statement happens if you have 6 other loudspeakers enabled in an AST setup, then the BL7.2 gets a one-channel feed from the AST algorithm.

Hope this helps

Cheers
