Found a drawing for the m464F cinema filter that allowed sweepable frequencies for the M646 style hp LP filter
Original m464 without the switch d resistor switches.
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.
Today I had the good fortune of meeting with Derek Heimlich of McDSP. Derek introduced me to a solution to a grief I’ve always had with software plugins. After his introduction and chat about this product, I blurted out that “Software has sucked, until now”
Until now no software allowed users to switch the character of an equalizer and compressor without loosing their settings. Modeled after some of the industries most revered equipment, McDSP comes through with another must have studio essential tool. This functionality gives you a true A/B between different compressors and equalizers. A unique experience. “I know what I want to achieve when I compress and eq, all I ever want to do is change the character”. As far as I know this is the only piece of software that keeps the EQ and compression setting between plugins. A+ work in my opinion.
I would suggest you give them a shot today for your next project. McDSP offers a free demo that is a worthwhile experience and great investment, check it out.
I was reading http://professional-sound.com/ (like I do every month plug plug) and saw Joels lovely new studio and Neve Console. Front an centre I was happy to see the set of WBS pre-amps I wired up for him a few years ago. Glad they’re making great records! And congrats to Thomas, who was apparently a regular at Revolution Recording… I just kept my head down and in the back
To better understand the behavior of a Passive Resistor Inductor / Resistor Capacitor I built another excel calculator….
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.
Loading up the studio on the last night got some AA stickers with numbers to follow! Most of this stuff is for sale with the exception of a few things…
I was talking with one of my teachers today about gold in ICs. All the gold is in the wires of big chips…
so I looked around and found another video about the PCB plating
THEN, blessings to youtube, there is a guy smelting it
The day Google unplugs, is the day the worlds knowledge disappear
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
you know… I love this man and am forever in his debt. He’s made laboratory grade audio equipment available to music / broadcast industry for many years and his standards and interests have grown since his beginning. Truly a childlike interest in pushing the boundaries of the craft he practices. He applies raw physics to sound and you should watch this as a whole to appreciate the brilliance of his passion and dedication.
I’m glad someone as enthusiastic as Hutch Hutchison is at his side absorbing it all. (though he left RND)
Long live limitless analog technology!
Long live the passionate, curious and boundary pushing!
Long live Rupert Neve
Top shelf tube gear has never sounded so good and been so reliable. Tristan has redesigned a classic and made it a price that’s hard to pass up.
Two channels of Passive and Inductor based Program Equalization!
Heavily modified version of the Pultec EQP-1, adding much more flexibility in the Low-End Boost/Cut, and in the High-Cut sections, with excellent Sowter inductors used in the High-Boost.
Single tube design, using one NOS Tesla/Sabre 6DJ8 per channel.
Hammond Transformers isolating both Inputs and Outputs.
You can buy one here: http://audioaholics.com/peers/catherine_north for MUCH cheaper than most mono tube filters!
You know you want one…
The Manley Massive Passive Stereo Tube EQ is a two-channel, four-band equalizer (with additional high pass and low pass filters) that can handle radical EQ sometimes needed for tracking as well as the most subtle shadings for vocals and mastering. It is designed to be a fundamentally different EQ but incorporates the best strengths of Pultecs, choice console EQs, parametrics and graphics. The difference is that the Massive allows twice as much EQ with half the coloration. It delivers huge HF boosts without sibilance problems and extreme fatness with impressive clarity.
Manley Massive Passive Features:
All-Passive tone sculpting circuitry
Unique Shelf curves use the “bandwidth” control
Overlapping and Interleaved Frequency choices
Every band switchable to shelf or bell
Vacuum tube make-up gain and line drivers
Parallel symmetrical topology
Premium components throughout
HP and LP Filters plus gain trims
Modular design allows future upgrades and special functions
