Hi, everybody.

Long time no speak.

Sorry for the absence. Since last post, 31st of Jan 2010, I was busy in experiencing a DIY plasma tweeter.

As a matter of fact a driver that could...

Dynamic Transducer Selection, part 2.

Sorry to have been absent for a while, but I was quite busy in gathering information on the plasma tweeter.
If there is a single possibility to have a no...

Here is what I meant by a small plug in circuit.

It is just a bit bigger than a standard regulator and the shielded wire (+12V and Gnd) from PSU 1 is connected to the top of this circuit.
See...

Low Noise Regulators.

When someone wants to get ridd of his dog, he says that it is sick of rage…

I have been on the URL where noise measurements on different regulators have been recorded.,...

Good you ask. All of us have pre-understanding on about anything according to our past.
Every body believes that such a driver would not work. Because of that this full range (20EX Model 7) is a...

Hi Vbro, pleasure to read you at night.

Obviously I was not clear enough on what I call a surroundless driver.
Thanks to point that out.
I believe the B&W midrange you speak of is the FST (Fixed...

Dynamic Transducer Selection.
Some would say it is a matter of personal taste.
But as said Audiophool, this taste might be helped with technical facts from technical experiences.
We have spoken a...

Hello, Scratchy.
I read AN4 again but did not find any answer on the possible link between input NFB and Modulator NFB.
May be I overlooked something there. Could you help me ?

T amps with Output Transformer.

Yes Vbro, I should have thought of that : Why not driving a pair of electrostatics (which start with an impedance transformer) by the 41Hz amps ? I’ll do that.
...

Well, well, it does'nt seem that DCX PSU inspire anyone.

Then let's go back to main purpose.

There is certainly more to recall about amps and speakers.
In active multi-way system, with...

Hi everybody.

Here is the same PSU with all calculated values.

Please note that there are two more 5VA regulators which should...

Thank You Vbro. I think I got it.

Please see on that URL the schematic of the PSU for the DCX as you just tought me. It look a bit complex but it proved to be appropriate :...

Could anyone tell me how I could join a pdf to my posts ?
Would it be taken as an image ?

Hi Vbro.

I have tried the different upgrade kits by Selectronic.
On power supply I am not convinced by what they propose. Linear Technology propose much more modern low noise, low drop regulators...

Ok Krilli, try that kit, you might love it.
But as I said the LM4562 do not drive anything else than the CS3318, that is the CS3318 that drives the amps.

Isomeblocke.

Correction, I mixed myself up.
The U6 and U12, OPA1632 are two differential OPA’s for the analog inputs and for referencing DSP inputs to 2.5 Vdc.
U1 to U3 are three dual OPA’s...

Hi, Isomebloke.

I am finishing myself a Linearaudio tweak kit for a friend.
Very nice kit. The IR volume control is a very interesting one.
Jan Didden, who built the kit, don’t give the...

OK, Tim, here is what I know on the DCX2496 available on the Net at 269 €

Inputs.
They are on XLR plugs that you could combine in different ways.
Three analog balanced inputs;
Two balanced...

Speakers
I think the best way to understand how and why we have to experience the properly phased multi-way system is to start with the simplest system, i.e. the full range driver system.
I am sure...

Hi Tim. Happy to read you.

When I said in this thread for other Knights of the Solder iron (How many are you ? Twelve ?) that I knew other knowledgeable people on this forum were interested in DSP...

Back to main purpose.
So this thread is about combination between amps and drivers on one side and DCX and the amps on the other side.
As a whole I propose a non exhaustive list of chapters to...

Krilli & Vbro.

No I don’t think we are far away of all the good things we have to test. I would like to thank you both for your comments.
After all balanced signal or not might be left as an...

Thanks Krilli to be more precise.

I do understand that single rail chips have already “bridged” outputs. I remember to have seen that on datasheets. I am discovering here that bridging does only...

Correction.

Would that simply means that dual rail chips may be bridged by having outputs in serie or in reverse polarity in parallel while single rail chips can be bridged by having only reversed...

Happy to hear from you Krilli.

I believe that we have never been closer of the future music in original digital format delivered by a computer in WiFi digital transfer to DSP close to the amps....
