Hi Geoff,
I have followed this thread where you made a comment about the Loudness-function on Beovision 11 and Beoplay V1.
I have a question to you regarding Loudness-function on the Beosystem 3 (or Beovision 7-55):
How much does the Loudness-function (Swithed "ON") boost the bass and treble on the Beosystem 3 mark III (or Beovision 7-55 3D)? Is it the same boost as with Beovision 11 (+12db bass/+9db treble), or is it more or less?
I hope you have the possibility to answer me.
Regards Martin Ström

Hi Martin,
The simplest answer is "I don't know".
However, the answer is actually more complicated than this, since the auto-loudness function on the BeoSystem 3 also has different turnover frequencies on its filters, and the actual gain applied to those filters at any given volume step will be different. So, a direct comparison of the maximum boost, applied by the systems at the lowest volume settings is only a very small part of the picture.
I'm curious as to why you ask. . .
Cheers

Thank you for Your answer. The reason I ask, is if it is "bad" for the sound-picture if the Loudness is set to "on". The speakers have their own calibration-system, and maybe all "tweaks" should be set to zero to get the most correct sound-balance from the speakers.

It may sound glib - but my honest recommendation is to set the Loudness to whatever you like better. Personally, I leave Loudness set to ON on any device unless I can hear it working too much at low volume settings. If you can hear the Loudness working, then it isn't working properly.
As I can remember loudness was "invented" to compensate the human ear, which is less sensitive for low/high freqencies at lower volumes.
So, a correct loudness function depends on the level of the volume control.
and on the ear and the room and the recording...

You can't design (loudness) filters based on the infuences of room reflections and or mixed recordings with personal and/or commercial infuences.
Room reflections are only corrected as done with the Beolab 5 internal DSP.
The first function of loudness is to compensate characteristic of sensitivity of the human ear.

Yup, only to compensate for the Fletcher Munsen curves.

I'm afraid I'm recovering from the BeoVirus.

Which is why it was called "physiological" filter in many implementations...
Anybody know how the "bass extension" function in Beolab 3000/5000/4500 panel speaker works? I suppose it predates the ABL concept as the service manual doesn't call it such. As I had to do some repairs to my 5000s, I studied the schematic and block diagrams. It has a 4-bit / 16 level control circuit for (apparently) the bass level, directly driven by the microprocessor. What puzzles me is that I can't find any input for the control loop - all the feedback from the output comes in the form of binary "turn the whole bloody amp off now!".
