Here it is: the JCQS-440 A.F.V. also known as the Wurlyscope.

I have a question. If you are using the line level feed to the scope, how are you getting them back into the stereo/quad inputs? Are you splitting all of them to feed the scope and your stereo?

No need for splitter cables!

Each input have a pass-thru output.
Plus input gain presets are provided to best match your equipment.
Have a look at the back plate markings.

WooHoo! Great! Thanks!

Can this also be used as an oscilloscope?

No

No, the display is not working with a time base like an oscilloscopeand is not X/Y based Like a crt.
It is specially designed to display the interactions between two or more signals. I call it an AFV. Audio Fields Visualizer.
An oscilloscope cannot show audio quite like this.

I do not have videos of the new and improved model but you can still see some videos of the previous model in the last pages of this previous thread: My DIY Audio Scope so far (will update)
And at the beginning of this thread.

I guess the mk-III is the one to go for you as it is as capapble as the mk-II for quad display (4.0)

The JCQS-440 is not a kit, it's a completely assemble and tested unit. I design and built them by hand few units at a time.

I will put your name on the list and contact you when i will have one for you

Excellent on it being a finished unit. I think I was on the list on Dec 3, but it's good either way.

What do the back 4 channels do in the mark 3 for "matrix?"

Thanks.

 

[Wurly1]

I will copy here the answer i gave in a private messager earlier.

Both models are not limited to quad, they all accept up to 9 channels.
the main difference for the mk-III is the channels 5 to 8 are fed through a matrix and fed to the Channels 1 to 4. The ninth channel is for the sub and they both have it.

For example, the ch 5 (center front) input is fed to the FL and FR ch 1 and 2,
the ch 7 (Left) is fed to the FL and RL ch 1 and 3 and so on.

in the mk-II, there is a switcheable » Matrix » mode which do just that.
Otherwise the mk-II have some bi-color LEDS for ch 5 to 8.

A new beginning…

mk-II screen taking shape!

Only a few more to go!
Have you got a simple jig to test every LED before soldering it in?

For the first mk-I last year, i did but i quickly realized the tester would wear out very quickly plus it is so time consuming that it became simpler to just replace the defectives ones if any.
The only test i do is a colors check when i change batch.

That would be cool to have a “demo mode” on the Wurlyscope. Something to impress your friends, or more importantly.......the ladies. Because as everyone knows, it is impossible for a woman to not fall under the spell of a functioning Wurlyscope. It is fullproof and scientifically proven, time and time again.

I must be using mine wrong!

The ideal demo mode would be to post videos of your best multi-channel audio file displayed on your Wurlyscope.
The Wurlyscope is a hard-wired analog computer designed to do only one thing. It add, subtract, differentiate complex analog values, ie audio signals, and finally display the results at near light-speed!
Maybe i could produce a dvd with testing signals for a 5.1 demo.
But now all my energy is on the assembly.

Not really knowing what I am talking about, but since it is an analog device it would probably require at the least a small ROM chip with the demo routines programmed in. And of course a ‘Demo’ button on the panel to disable regular “Wurly mode.” But how that would all work past that is beyond me. Maybe a very, very, small traffic cop inside to route the signals? It might work.

Analog devices have no use for ROM chip

That's analog all right!

 

[Wurly1]

The sub is hot!

 

[Wurly1]

More pcb!

Now that i have all the pcbs for the mk-II
The 3D jigsaw puzzle begin

 

[Wurly1]

The first input amplifier is completed!

...too tired to test it tonight

Believe it or not, it was cheaper to buy already assembled Chinese relay module than buying the relays alone.
