Patent input selector by Z audio

Thank's to the Admin.!!!!
If I like the politics I would not be here on the forum.

After 21 posts, everythig is OK.

What hapened with Schematic?

I don't think this idea is anything new. Looks to me to be a set of latching relays, where each momentary switch on the front sets one relay and resets the other four. I briefly considered this setup for one of my projects, but decided against it because of its higher parts count over a microcontroller solution.

Also, you said you didn't want to use a microcontroller because of noise concerns? If so, I would definitely avoid using a (likely switchmode) wall wart power supply. An internal linear supply would be lower noise.

Hello amc184!
First this unit uses simple dual contacts to switch L&R channel and is not latching relays .They are Nais If you want I can give you original part number and they have 8 pins 2 for the coil and the rest 6 for switching!!!!!
I am also using Motorola external power supply but not Switching mode, Just linear, and inside input selector I have Voltage regulator for 5 volts with 2200 input and 1000 microF at the output.
Thank you!

good work and nice box
and good working, too

If was anyone other posting this, we would say Great!
How did you do it .. can we build from your layout.

Nobody can stop you from keeping secret.
Nobody can stop you from paying money for patent.
It is your business.
It is not diyaudio .. at least not for me

Good luck.
Do not listen too much to bad comments, zoran.

Thank you lineup!
Of course that is possible to make this device because it is working and as you can see nothing is fake here I am just telling the truth.
I don't have any job in the present time but I can work with audio things 24 hours and don't get bored.But this situation here is not so good and I don't like to work for 100 euros per month!
The schematic of this is not wrote on a paper or in the computer, I did not have time for that because was occupied with hardware work on this device since I did it first experiment and it worked.
So I need a time to think what to do with this project, everybody wants the schematic, but maybe this is nothing new,perhaps it is done in other fields of industry, I am not sure about that.
I think that this similar can be done by using a logic circuits 4000 or 74...series, but I never tried that, and about a PIC, I eliminated because I am not very big fan of any digital here in my audio system but I also listening music from my Marantz cd 67se cd player, It sounds very close to analog!
So please wait, I need a time for rest and think about this, If you don't believe it I am ready to show this personaly, of course with coffe sum cigarettes and a good music.
Thank you for wishes about our nation.
By best regard.

This is an input selector. The signal will pass through the same relays the exact same way regardless of what drives it - unless you've got some sort of buffers, it's a completely isolated circuit.

What a load of bosh.

[zoranaudio]

Yes, it is just input selectors and it's good you got it.
You can do this manually by connecting and disconnecting cables of all units!

If You wanna patent this - there is my "prior art" . I built this more than 10 years ago. As relays switch I used mechanical switches, but SAS580/590 can also be used (if still avaiable, datasheet is on datasheet4u.com), so it can work like Yours. Beside input switches there are two buffers. One with op-amp for amplifier, and one with these two metal-case transistors (emiter follower) for tape output. Schematic is in my head, but there is nothing more than written above - just input switch and two buffers.



P.S. sorry for photo quality - it is the best than I can get with my cell phone.
