Audio Precision SYS-2722 Service Manual

Does anyone have Audio Precision SYS-2722 Service Manual available?

Hello,

Even though there is a document named "service manual" for the system two range of analyzers, there is nothing available that is useful for repairing.
I have this manual and it only contains the calibration and adjustment procedures. Don't be fooled by the drawings - they don't show anything. And it is difficult to get and expensive.

Perhaps the end of the AP2700 series (and previous ones a long time ago) would let AP to publish actual service manuals (like for the  system one devices), but I'm not very hopeful...

I no longer have access to the SYS-2722 anyway.. great piece of equipment though!

Hi Jerome,
Is there anyway you can share a copy of this manual with me? I have a 2222A that needs some post-repair adjustments and AP is not willing to help.
Many thanks,
Duong

After a couple years, just checking if anyone has SYS-2722 from Audio Precision service manuals.. AP has really seriously stopped support for this model. A unit I have just started giving connection errors:

• Incident code 66646 on startup
• Error 8501: undefined DSP error
• Error 8611: an error has occurred, probably APIB

AFAIK Ap did not release the service manual for sys-two after IP was stolen by competitors via the sys-one service manual that was available to the public.

When my SYS-2322 got broken I had to reverse engineer part of the board and thankfully it was just an op-amp to be replaced.

If something containing a software (a CPLD) got broken in your device, you are basically screwed. On the auction site there are spare boards for sale. Think about that.

There was a old AP box group on linkedin but I am not able to find it anymore. There is an ex AP employee checking the forum. Maybe he will step in. I know he offers repair service for the discontinued models.
