This is such a basic question, but please... One name that is repeatedly repeated in all mic forums is 'Alice'. What is the original source for this?

A bit of perspective on component selection: as far as audible performance goes, the only parts that matter are the capsule and op-amps. If this were food, the capsule is the cut of meat and

Indeed they are! That is a very insightful thing to say and I'm glad you're posting such high quality responses.? ;) -Scott -- ---- Scott Helmke ---- scott@... ---- (734) 604-9340

Yea, 40 years ago when I was a younger engineer, metal film resistors were an improvement over carbon composition ones of the day. Same with capacitors etc. I’m certain we will have some golden

Components not compliments wrote:

I have built quite a few of these with absolutely normal 1/4 w resistors from Amazon and they perform amazing. Compliments are really made to a high standard these days and most things will be just

Thanks for the positive feedback on my OPA mic instructable. I will look at the ".22nF" on the instructable schematic. I use metal film resistors and 1% for all of it except for the 1Gig, which is 5%

The importance of matching these resistors is quite exaggerated. For a strat, the legs going to pin 2 and pin 3 are different. One takes its source from the source of the FET, and the other from the

Hi everyone. I'm currently in the process of building an OPA Alice based microphone using a NW-700 body and TSB2555B capsule. Jules instructable is an amazing guide that makes it trivial for anyone

So yeah, I forgot to actually make my real point - what's the current flow for the DC bias? ?What's the best resistor for that Sony wireless, in other words? It might be a little while before any

There can actually be interesting coincidences in life. Ferrari are not very common. But because of the weak yen, Japan is very attractive to international tourists from all over the world since a

Heinz - great catch! And nice feel of the space. This recording is special in several ways - you managed to record not only a Ferrari but also passers by speaking in Polish. In Japan. Sure, there are

Thanks, Scott. The only reasonable images of the DPA CORE "preamp" (their word) is from a DPA promo video ( https://youtu.be/NMLvT8cYbwE?t=138 ) , where they also say each one is "tuned to match its

Scott Helmke <scott@...> added the photo album DPA 4066 capsule FET ( /g/MicBuilders/album?id=295709 ) : Closeups of the FET and other components found on a DPA 4066

As somewhat expected, the photos disappeared. The album can be found here: /g/MicBuilders/album?id=295709 -Scott

OK, so I happened to have a DPA 4066 headset capsule on my bench - I work for a company that rents out audio gear, including a lot of wireless with DPA mics. So this one showed up as unrepairable due

What I particularly like about binaural recordings is the spatiality and the fact that one can clearly hear from which direction the sound is coming from. I recorded some city sounds in Osaka last

I really like binaural and related near-coincident? degreetechniques for my hobby recordings, which are mostly soundscape or nature. I've been making them ever since getting a pro Walkman stereo

Maby I have not the right gear for good ORTF, but besides binaural, I like the recordings I've done with my downsized SASS. These sound good on stereo speakers too. Experimenting with Jecklin disk and
