FYI, Amazon is now accepting pre-orders for AverLAB. They actually have units in inventory right now but I guess their holiday inventory preparations have slowed them down a bit. Units can also be ordered directly through us. BTW, since we are doing Fulfillment by Amazon, Prime members get free shipping.

Checked Amazon.
It seems that it does not ship to Hong Kong.

Maybe, I need to order it from Avermetric directly.

Great, but Amazon also don't ship to Denmark, I assume I can order one directly ? Actually, I don't understand why you're using Amazon at all, they really are consumer oriented and the AvarLAB I wouldn't call a consumer product.... You really should just set up your own little webshop with credit card processing, it's not that complicated nowadays....

And if they're shipping, what about putting the full manual up so we all can take a look ?

B&W Arthur, thank you for noticing this. Our Amazon export setting was disabled. I have enabled it but it could take 24 hours for this to take effect.

Søren, we are feverishly working to get the manuals ready. There should be some documents up by the end of the week.

Just wanted to let people know that the first pass of the user manual will be posted this weekend. Also, we just added the feature to compensate for the use of external attenuators in time for Burning Amp this weekend. The new release should be available tomorrow.

folks, what does this mean? autoranging vs single range? What's the residual nosie actually?

SNR, +26 dBu out, autoranging, typical: 145 dB
SNR, +26 dBu out, single range, typical: 126 dB

I too could be interested in something like this. Been scouring ebay for a good deal on an AP or dScope for quite a while.

Are the inputs and outputs isolated from ground ?

cheers

The power supply for AverLAB is an inline switched supply with a 2-prong plug. So in essence it is isolated but of course there are always stray currents. Good grounding practices are always important with any measurement system. Is there a specific scenario you are concerned about?

I believe the Audio Precision analog inputs are floating because some amp outputs have a large DC offset value above ground.

Also is the signal generator digitally generated or done by analog means ?

cheers

All AP's utilize a 3-prong plug and good grounding is an issue with their systems too. There is a limit to how much common mode they can handle. I can't recall what it is but I recall it becoming an issue in some situations.

AverLAB uses a DAC to generate signals just like most of the APx models. There are only two current AP's (the 2722 and APx-555) that still contain an RC oscillator. RC oscillators outperform DACs when it comes to residual distortion and noise but they have certain drawbacks. First and foremost is the cost. Either of those APs start around $30K.
