Hi Geoff, 

In the sound guide for Beolab 50 I think there is some technical spec for Beolab 90 instead of Beolab 50:

10.2.3 DigitalSignalProcessor
Model AnalogDevicesADSP-21489 Number 2 InstructionRate 400MHz Samplingrate 192kHz(fixed) Notes 32-bitfloatingpoint

Here it should be ONE Digital signal processor for Beolab 50. 

10.2.4 DigitaltoAnalogueConverters
NotethatthesespecificationsincludetheanaloguestagesthatfollowtheDACoutputs. Model TexasInstruments/Burr-BrownPCM1798 AudioChannels 18 Samplingrate 192kHz(fixed) Wordlength 24bits FrequencyResponse 0Hzto40kHz(+0dB,-1dB) FrequencyRange 0Hzto75kHz(+0dB,-3dB) THD+N 0.004%(997Hz,-1dBFS,22Hz–20kHz) DynamicRange 122dB(A)(997Hz,-60dBFS,20Hz–20kHz,AES17) ChannelSeparation 110dB(20Hz–20kHz,AES17) LevelLinearity ±1dB(at-120dBFS)

For Beolab 50 it is not 18 audiochannels, it should be 7 instead. 

Im I right?

Best Regards
Martin Ström

Hi Martin,

You're right... One of the problems with being my own editor is that it's difficult to see my own mistakes.  Thanks for spotting these!

Cheers

Are you planning to do more youtube episodes as well? As a complete audio dummy I find myself well educated by you.

"Planning" and "Doing" are so far from each other these days...

The acoustic tutorial videos are a hobby thing, not a work thing - and the weather's been too good here lately... so my weekends are filled up with dog walking and grass mowing and standing around with a high-pressure washer instead of traipsing around with a camera, making funny noises... :-)

So, to answer your question, yes. I'm planning on it. But I make no promises on WHEN it will happen...

cheers

I've watched these videos and found it a nice visible way to see what happens with the acoustics in different rooms. Much more easy way to understand than years ago where you needed to draw and calculate yourself on a piece of paper. Call it the advantage of nowadays simulation programs. I've pointed others in this YouTube direction if they want more insight/understanding of what happens in different rooms. 

Just wondering whether you still have your "home loudspeaker" (looks like an inflated Beolab 1/Beolab Penta) or whether it is replaced by a nice pair of BL50/90

Isn't there a word for this? Procrastination..😎   Something I always have due to the pile of things I want to do and learn.

Hi Geoff, 

One for the plan and do (unless im doing something incorrect) is to overcome a bug on start-up volumes. (as opposed to default volume).

My BL90s love going to full tilt (Vol 90) when I play via an Auralic Vega G2 DAC and XLR. 

You have to be very tentative on the B&O App that the slider does not move all the way to max.

Another "Bug" is the trigger sensitivity of XLR - I have this on at -76db but usually I get 20-30 seconds into a track before the BL90s fire up. This may be the processing time, it may be the noise floor - which will be very low on the Auralic.

Any thoughts?

I still have the "homemade" speakers - although they're disconnected.

My wife told me that I was not allowed to NOT buy a pair of 90's. I promised to love and obey. ;-)

I prefer to think of it as "prioritisation" instead. This is a form of rationalisation...

Or, as Bernard Williams said "I like the word indolence. It makes my laziness seem classy."

The disadvantage of this is that, if this wakes your loudspeakers, and you never turn off the Auralic, the 90s will always be on, which is a stupid way to heat your house.... Cheers -geoff
