JL Sub-Woofer

Took a look inside a JL subwoofer… quite the coil and suspension system.  http://www.jlaudio.ca/home-audio-powered-subwoofers-fathom

JL audio dominates the Car stereo market in terms of driver quality.  The salesman said the best line “We learned a lot from our 12 Volt line of products in designing this home theatre sub”  so from now on, Car audio will be forever “the 12 volt industry”

rom the sale:

 

Up for sale is a rare 1970’s Philips LDC25 console. The console features 24 transformer balanced mic/line inputs, great sounding 3 band EQ, 2 aux sends per channel and 4 transformer balanced output busses. 16 of the input channels are early discrete LDC modules and the last 8 feature later 1970’s IC based modules – both sets of modules sound, for all intents and purposes, identical. The sound of this desk is punchy, clean and very hi-fi sounding – easily on par with anything built by Neve/Api/Studer from the same era. These were built by Philips in Holland for recording mostly classical music, but were built to a very high standard and also sound fantastic on modern tracks which require a very forward sounding mix with a very low noise floor. I bought this to use as the main console in our studio due to the high build quality, high track count, compact size, multiple sends and versatile output options – but I need to raise money for the completion of our house restoration which takes priority to the studio build out. All the manuals and module documentation are included. The console will be fully gone through by a qualified technician prior to shipping and/or pickup. All input/output wiring is terminated to panel mounted XLR connectors, so all you need to do is connect the console to your DAW/tape machine and you are ready to record – no wiring necessary.
The console is located two hours west of Chicago in IL. I’m happy to assist with freight shipping, but please understand due to the fragile nature of vintage electronics any risk associated with shipping is going to be your responsibility. Local pickup is welcome. Payment by check or wire transfer only for this listing. Please feel free to contact me with any questions you might have. I hope this console finds a good home!

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!

Ward-Beck Systems “DINNER BOXES” dB-4

Well after some time away, I’ve gotten back to the Dinner Box

The dinner box is a PCB that users can solder EDAC connectors that mate with Ward-Beck Systems Auxiliary modules.

With a standardized 5 PIN XLR power connector, users can simply power up (4) WBS filters and Compressors.

In Addition to power and audio, there is the interconnections stereo linking of the M466 compressors using either M466M OR M467 Noise gate modules.

the dB-4 also allows user to mix and match equalizers: any of the M462, M462A, M462B or M464 Filter interchange seamlessly into this bucket.

A balancing card for M472 eq modules is on the drawing board.

Here is a revised version.
The major change is the addition of XLR connectors… The idea of using a dB25 connector is now optional!

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

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


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.
