DIY Audio Analyzer with AK5397/AK5394A and AK4490

Hi mbrennwa,
Have you tried to run it under Wine? It should either abort or run.

-Chris

 

[zfe]

No the firmware upgrade does not work with wine - I needed to find a windows computer to do it.

 

[anatech]

That's too bad.

A windows laptop would probably be the easiest unless you take the RTX to a friend's with a windows computer.

I just think it's wrong to limit the performance of the RTX6001 by the availability of a given computer operating system (especially if it is proprietary and not free). There were some mentions of using Python to upgrade the firmware on the RTX. Did anyone follow up on this?

It is basically free for this purpose. You don't need an activated copy to run the firmware update.

Now there's some clever thinking! Nicely done Chris.

[mlloyd1]

yes, it is the same.
it comes with the updates already installed.
and comes with a calibration certificate.

Hi niner,
It should be the same. I would expect it will be fully up to date as far as modifications and firmware is concerned.

You're going to love it!

Thanks guy for the confirmation! I missed the GB last year. Now I just need to save up a few more bucks to get one from RTX.

Good idea regarding the Windows update

At the moment there are no planned firmware updates though.

I think mbrennwa refers to free as in free bear not as in free beer

I meant free as in free speech, not as in free beer.

I have run into a situation. After adding the components of the upgrade kit, I get over voltage in the right input channel. Any ideas what I should look for?

 

[anatech]

Hi soogsc,
I guess it's down to checking your work.. Look for correct positions of the wire and shorts between pads. I would remove all the flux in order to see the board clearly. A magnifying glass wouldn't hurt either.

Good hunting, I hope you find it easily.

-Chris

 

[JensH]

Please check wires for shorts and/or missing connections.
If you can post a sharp picture of the PCB and the connections, I might be able to help identify the problem.

In what situation do you get overload on the right channel? Is it always in the overload condition, even without an input signal?

 

[soongsc]

Yes, it is always overload without connection.

 

[JensH]

On the main board two resistors have to be removed (per channel, shown as R521 and R522 in the mounting instructions). Could the pads of one of these resistors have been shorted in the process?

 

[soongsc]

I did not see the instructions to remove resistors.

 

[JensH]

Please take a look at the document provided here:

GB for RTX6001 Audio Analyzer with AK5394A and AK4490

 

[zfe]

There are two modifications, the early overvoltage and the later oscillation modification. Are you sure that you speak from the same mod!

 

[soongsc]

I was talking about the mods using the kit mailed to us. I guess I have to check again.
