Hi all!
I was given a Audio Precision sys 2522. It's got all the parts and cables, but I can't seem to find the software anywhere. Darn discontinued equipment. Looks like they could have an archive of old software.
Anyway, Does anyone have the installer for this beast?

If you create a log in at ap.com , they have all the software for download you want.

That's what I thought .. they dont have any for discontinued products. They hit EOL and it seems they just delete everything 🙁
It's still available:

Edit: looks like for 2522 you need Ap2700 V3.3 SP2 (Jan is right):

The 2522 will run on ApWin 2.24 or 2700 software. You need an interface from the PC to the AP.
1. Old PC with motherboard for AP card.
2. APIB USB ADAPTER with ApWin 2.24 XP, Vista, Win 7,8 or 10 I have the ADPTIORS in stock
3. USB BOX from AP and 2700 software.

Hello,
I join this dicussion. I will get an AP SYS-2522 soon but without any cable.
Is there any solution ? Build one for example ? But then I need a special card inside PC if I understand well.
The solution is probably the USB adapter. I found 2 kinds of them:

Any advise ?

Hello All
Your best solution to run the System One, Two or Cascade or ATS2 is an APIB USB ADAPTER (INTERFACE) from PC to AP is USB. Like i said in previous replays. AP has no current support for the older products. I have the adapters in stock I sell them $375.00 and also have them on EBAY $425.00 duke.aguiar@ieee.org

oooh, that is old junk, prepare yourself to repair that soon! I bought the same(made in 2000) 3 years ago and did replace some Fairchild logic(stop working when getting warm) on the DSP board 3 times!
So the good idea was to replace all these logic chips at once, but an even better idea do not buy astronomically overpriced AP at all because you can easily outperform SYS2 performance level today with ADC/DAC 😉

My 2722 has developed a problem ... The output levels are about 1/3rd of the settings in the gen panel.
Single ended as well as balanced, and for both channels.
Setting output to 1V gives about 354mV. The distortion/noise performance is not affected, only the level.
I was thinking, 1/3rd is close -10dB, which is 316mV, so maybe some 10dB attenuation relay got stuck.
Looking at the documentation (I have the S1 schematics, which are largely also valid for S2), I don't see any 10dB attenuator or gain setting.
Any idea where I should start looking?

Ahem ... My face is deep red ...
For some reason I inadvertently set the output level to Vpp instead of Vrms ...
I should have more trust in the people at AP.

Jan, I like people can tell the truth about themself 😉 Did you repair your AP yet? My 2522 is 22 years old so I am always expecting some troubles.
No I never had to repair it. I think it is from 2004.
But I am very nice to it, never insert a signal into the output!

Hi Jan
One thing about the AP is the DUAL BANANAS on the Generator outputs as it gives me LOTS OF REPAIR WORK from inexperienced technicians.

1/0.354 is 2.824859. Which is a lot like 2.828... (0.01% error) I admit this did not strike me at first read.
Is there any major difference between APWIN and AP2700?
Regarding soundcards vs AP I do believe there have been wonderful cards for the past 10 years already, but the main issue with them, at least in my experience, is the output noise of the generator and offset when you use it to measure a phono amp, and the fact that al measurements are really highly level dependent.

My 2522, and I believe 2722 the same thing, has residual analyzer's THD+N -120db@1k with the sine source DAC+LPF(THD+N something like -135db, Cosmos APU shows me -132db). APx555 about -125db.
However, 2522 loopback THD+N just -117db in the best case i.e. AP's gen is worse than its analyzer. About the performance level, I don't know any sound card with ADC's THD+N close to -120db. External ADC based on modern ESS chips may have THD+N -125db@1k without notch filter.
PS: for all AP analyzers is a good idea to use a higher input range than auto-selected one, in case if you evaluate the H3. If you looking for the 2nd harmonic, better to keep auto-selected or lower range(the same for the THD+N to minimize the noise).

Thx for the reply!
I am about to get a 2522 just this weekend perhaps. I thought TDH+N on the AP was -113db and -120dB for the APx555.
I have been successfully using a simple combo with emu0204 plus spectraplus for analysis. I observeddistortion is level dependent, plus you are limited with the max input (1-2VRMS)when you try to evaluate something. Also I have problem measuring a transimpedance stage Thwt has very low input impedance using a sound card. The generator will produce a bunch of harmonics.
Since you have a sys2522 would you ever consider selling it and only use the audio card or a QA403?
Can you think of any pro and cons of ap vs a sound card based system?
Thanks!
