sound guy Xmas idea: APx515 2-Channel Audio Analyzer

Posted on by

This would be a dream for the test bench.  Simple, robust effective analysis tools!   I would be happy with an old system one… but this would be on the shelf in a heartbeat.

The APx515 is a high performance audio analyzer optimized for production test. APx515 has a typical THD+N of –106 dB, a one million point FFT with 24-bit resolution, and 192K digital I/O. It is a best-in-class instrument for its combination of speed, performance, automation, and ease-of-use.

APx515 is a significant product because it delivers the performance and reliability of Audio Precision at a production-level price.

APx is the fastest audio analyzer in the world, returning 21 audio measurements in as fast as 1.2 seconds. It is also the easiest to use, with one-click measurements, custom reporting and sophisticated automation without any programming. A full API and LabVIEW driver is also provided.

This speed and ease-of-use means test will never be a bottleneck, and production line managers can achieve reliable, consistent results compared to the current low-cost alternatives like a distortion analyzer.

For companies outsourcing their production, requiring APx515 on the production line gives tighter control over production, ensuring manufacturers are meeting their contractual requirements.

Moving stuff across the country

I most certainly had a busy “reading week”.  It started with finishing up a job My brother Mike started.  Moving 7 pallets of equipment from my moms garage in Saskatoon.    Followed by great visits with Family and friends.  I’m sorry I did not get the chance to meet with everyone I had planned to visit with.  Things got a little busy in the IT support world and there was so much family to visit!

Modules were packed, boxed and palleted.  A small fortune in bubble wrap and pallet wrap were employed.

I’m excited to work on these projects again in my “Spare time”

Stay tuned for updates of what’s happening with this lot.  We’re very excited for what’s planned :-)

Working on the new Ward-Beck Systems “DINNER BOXES”    dB-4

Because there’s real Meat in it… Because sometimes I skip lunch… Because they don’t serve lunch at 4AM… Because I eat lunch for breakfast…

It’s a backplate to simply wire and power up (4) WBS filters and Compressors.  M466, M466M, M462, A, B or M464 Filter.   A balancing card for M472 eq modules is on the drawing board too! Screen Shot 2014-08-21 at 9.06.06 AM Screen Shot 2014-08-21 at 9.05.24 AM

RLC calculator for components in series

I’ve been calculating a lot of components in series lately for an ECR255 class. I’ve also had to graph them on impedance diagrams and a power triangle.

In an effort to better understand the math I made a calculator for myself. Here is it for you to use and enjoy. If you see any problems please let me know. It was designed in excel 2011 for mac… there WILL be compatibility issues and I hope they’re minor.

How it works:

You can fill int the info you have in the orange boxes. Once the boxes are filled in the calculator should fill in the rest.

If you need to modify anything else, it’s all dependant on the orange boxes. I suggest a goal seek by modifying and orange cell.
