Are there passive attenuators that don't zero volume and only offer one input ?


I am not sure how many people would like those features, but its worth asking in case someone would try to sell such a thing.

Which is to say it is essential I should think  to be able to zero volume, and have more than one input, do you agree ?

Let him go ieales, never have I met such a persistent BS'er as him, for years now on many forums trying to make a quick buck from the gullible, he’ll self implode one day.

Cheers George

@dbxrecord OP

Please deny again for the record

1: That you are Chris Daly
2: Have any associations with
a: Stereo Coffee
b: Java Preamps
c: Opamp Pass transistors
3: That this you https://ibb.co/yqH11rj

See ieales BS baffles the gullible, that’s his game.

Cheers George


He a shyster ieales, and known all over other forums
All you have to do is see how he disowned his own name and product, in the proof I posted up.

This was the best one he tried to sell on ebay and diyaudio he called a "Pass Transistor opamps" https://ibb.co/Db3yj9s see the little smd transistor squashed under the opamp with the "snake oil" he tried on

There’s only one reason he is here, to promote snake oil he makes.

Chris Daley? JAVA ldr passive preamplifier $3.5K!!!!!!

dbxrecord OP (aka Chris Daly)
I have no association with either name, please stick to the subject rather than libel.
How’s that for a outright lie!! How does he live with himself? Chris! you are certifiable.

From his Stereo Coffee website contact info https://ibb.co/hDwKkVV
and him preaching his snake oil at the NZ coffee shop Java ldr release. https://ibb.co/yqH11rj

Chris Daly has been criticize by some very knowledgeable electronic designers on many forums for his BS trying to get sales from the gullible, he’s even tried to claim the Lightspeed Attentuator, it’s about time he disappeared.

You’ve been caught out sunshine, you want more posted up from diyaudio also

And this is the "Chris Daly" famous opamp "pass transistor" con job, which you use as an avatar!!!! here https://ibb.co/HKwPhsh

These are my last words, I'll leave the rest to admin come Monday if you continue.



Whatever, why did you start this thread, if you know all the answers 


The S3 ’s are widely all over the place, almost impossible to get few "quad matched sets" to do a Lightspeed properly with close to zero volume low volume, unless they are forced matched with servo feedback arrangement and by over driving some which "raises the distortion substantially" to meet the others which will kill them over a very short period.

But what I observe is other LDR attenuators, based on what I have learned may be the NSL32SR3 type of LDR, apparently these can offer better audio characteristics, namely lower distortion, the manufacturer Luna Inc stating "best distortion characteristics" and also as I understand, providing wider resistance range.
This is BS, do your own homework.
The very best is the NSL32SR2S and is the most expensive, second is the NSL32SR2.
The R3 is the cheap one and doesn’t go low enough in volume unless over powered/stressed and won’t last if done so.Cheers George
I personally never liked TVC units myself.

I agree, TVC passives are usually colored, softened in dynamics, also in the frequency extremes. I would say they might appeal to those that like laid back SET tube amps.

BTW: before anyone sez anything "snidely"
I’m NOT trying to sell the OP a Lightspeed Attenuator (I’m sure he can find a used one somewhere) As all my production has stopped, till this Covid mess sorts itself out, so OS shipping is back to being reliable, as the last one took 3mts to get to the customer.

Cheers George
I don’t know either, maybe a safety factor against accidently leaving things running, works for me sometimes when I’ve had a few too many🤷‍♂️🤷‍♂️

Are there passive attenuators that don’t zero volume and only offer one input ?

The op wants a passive pre with one input, that doesn’t go to zero, all the ones mentioned above do zero the volume.
As far as I know only the Lightspeed at minimum volume still has a small amount of output, as Light Dependent Resistors (ldr) can’t attain absolute zero impedance.

You've just described the Lightspeed Attenuator to a tee.
