sound guy Xmas idea: APx515 2-Channel Audio Analyzer

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!

Three consoles were packaged and palleted up for shipment across the country.

Custom made dollies were built for the two large sections of console frames.

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 :-)

Visualization of what’s on your hard drive

I was introduced to “Disk Inventory X” that displays a visual representation of what’s on your hard drives. Within minutes I identified HUGE files that were plugging up my laptop. The worst culprit is parallels… but I already knew that virus was huge!

By selecting a file, you can reveal it in the finder and see what it’s really doing!

I would recommend checking it out, just for fun!

Herman Miller Chair repair

My Old Herman Miller wheels were really ruining my floor.  This is something you don’t really think about until it’s too late…
I ordered hardwood floor safe wheels for my chair.  I really recommend them for any surface… the soft rubber really keeps your floor looking new.

While I had the chair upside down I thought I’d share a mod I do to them.  If you’ve spent a lot of time in these chairs you’ll know the KLANG the legs make… to keep that klang down to a minimum I Supper 77  in some scrap acoustic foam to the legs.  2014-07-31 22.18.32

Due to popular demand: Ward-Beck Systems RTO-214 Rack Mount Chassis

Due to popular demand:

Introducing: the Ward-Beck Systems RTO-214 Rack Mount Chassis


APKaudio and Ward-Beck Systems are excited to announce a new lineup of retro products. Started with possibly the most requested and in demand item the WBSps.ca has needed: 

a 2RU rack enclosure for (2) 14″ WBS modules.

Most rack users have a 3RU box to enclose (2) WBS modules. With Studios shrinking in size and gear filling up the cramped racks with all the killer deals these day… there has been a need for this enclosure. 

Originally designed by veteran WBS fabricator Erwin S. for the current lineup of WBS AMS-8 products. The design updates and fabrication are carried forward by Shop Manager and Mechanical designer at Ward-Beck systems Dave Adams. Dave is a master metal smith utilizing the tools that built the modules WBSps users want to have rack mounted. Dave has been working with APKaudio to create a stable platform in a 2RU enclosure.IMG_0573-2014-05-05 IMG_0577-2014-05-05 IMG_0584-2014-05-05 IMG_0585-2014-05-05 IMG_0586-2014-05-05 IMG_0589-2014-05-05 IMG_0596-2014-05-05



The BUM (Back Unit Mount) will be pre-punched for however you decided to wire it. Power options and i/o varieties make for easy design.

Future options will include:
– Internal Power supply
– DB25 pre-wired breakouts
– DB25 to EDAC connectors for the modules of your choice

It’s a banana now, but it will be ripe summer 2014!

Going to re-manufacture some WBS daughter boards

As a part of my school program, I’ve decided to take a shot at re-designing 2 WBS components.

First the 4-110 mic pre-amp for the M460 – M461. In the 90s WBS redesigned the card using 5534 but I’m looking at something even more modern.

Second the 109 cards. While at Revolution Recording, Joe D redesigned his version of the 109 card and it was a HUGE improvement. He described it as “taking the cheese cloth off the audio” and he was right.

The idea is to have a plug and play module available for users with a few new features not incorporated in past designs.

Once they’re done I hope to have them for sale on www.AudioAholics.com

Had a date with a dream machine

I did a house call this weekend on a sick A80. Track 2 was being glitchy so it was replaced with track 15s chassis and pulled for bench service. It’s really nice to see these machines still kicking like it’s 1974! Making great records still!

A project I’ve been working on has come… full circle ;-)

Congrats to Kevin Park and the Lacquer channel team for getting the Neumann VMS70 back in the game. A fantastic project to have been a part of! We recapped the entire audio electronics for Kevin before he had lathe aficionado Chris Muth calibrate it. It’s a fine precision piece of audio electronics and Kevin is one HELL of a lathe mechanic and cutting engineer! It, and he, are in good hands over at Toronto’s Lacquer Channel. I’m excited to cut a few plates myself!
