Photo/audio 1/4″, 3/8″, 5/8″ threads confusion

Photo/audio 1/4 3/8 5/8 threadA lot of people keep asking what to use for flashes, Zoom recorders, professional shock mount 
microphones adapters and their DSLR

1/4″ 20 threads per inch is the thread size used on photo and video camera mounts and tripods. Your DSLR camera is having a 1/4″ thread female mount and your DSLR tripod is a 1/4″ thread male mount. Professional microphones (like those you see on stage at rock concerts 🙂 ) use 3/8″ and 5/8″ thread mounts.


The 5/8″ 27 threads per inch  mount is popular in USA, while the 3/8″ 16 threads per inch (55° flank angle) are more popular in Europe.


For example, a usual zeppelin (blimp) shockmount would usually have a 3/8″ female mount. An usual stage microphone clip would have a 5/8″ female mount but they most of the time come with a simple to 3/8″ adapter or a double 3/8″ and 1/4″ adapter.


Zoom recorders (like the popular Zoom H1) are different beasts. Since they are built for photo and video enthusiasts, they come with a 1/4″ thread. This way, they can be mounted directly on your photo tripod, without any adapter.

I hope this crazy thread thing is more clear now for you.
Oh, and I did NOT opened the 55° vs. 60° flank angle subject 😀

“An unexpected error occurred. Something may be wrong with or this server’s configuration. If you continue to have problems, please try the support forums.” wordpress problem – solved

It happened to me to get the nasty “An unexpected error occurred. Something may be wrong with or this server’s configuration. If you continue to have problems, please try the support forums.” message trying to install a new theme or plugin.

WordPress version: 4.7.

Solution: check the resolv.conf file. For some strange boot hiccup, my resolv.conf file was empty. 
The problem appear when wordpress has no way of resolving names.

Solution: check /etc/resolv.conf file for a “nameserver x.x.x.x” line.
If you have no idea what am I talking about, just insert there “nameserver” without quotes.

Problem solved.
Have a nice day 🙂

Why some live vocal microphones sounds better than other

Secret capsule

Live microphone capsule

(and they give you zero feedback, no matter what the **** your vocalist decide to dance right in front of the speakers)

It is because clever band technicians (and we are talking about The Band Technicians, not the equipment renting company technicians) are interested in the success of the show (they must live another day with the same artist 😐 ) and in making everyday life easier.

This is why, these guys have great respect for microphones like SM58, but they never use them (well, they use them when they can’t find the hammer :P).

For example, there are some well-known microphone manufacturers every artist wants to use because “they are so good” and as a technician, you can’t disagree – losing your job not being an option these days.
However, what one clever technician can do, is … changing the capsule 🙂
Making this more or less evident (visually) for the artist is, well, at the hand of the particular technician.
Enough said.

What I actually want to present you today is what a geek microphone creator made out of his mind.
You (probably) know that Heil is producing expensive(ish) capsules 😀
Well, what is interesting is that, these capsules, not only have a very low handling noise, but also very interesting other proprieties. This Heil technician discovered sorbothane, a material used at the time by NASA. Well, nothing fancy, rubber is good enough for a microphone, right?

See here what sorbothane is and how can you hit an egg with a large hammer and not break it (egg or hammer :P).

Electro Harmonix 12AY7 Mic HUM problem – $33 solution for newbies

Electro Harmonix 12AY7 Mic HUM problem – $33 solution for newbies

Have you got an EH 12AY7 Mic pre with hum problems?

Well, I did and this is how you can nail that annoying noise:

1) buy a short XLR to TRS (“stereo” for us, newbies) Jack cable (it should have a XLR female and a TRS male jack) – around $3. If you find the TS (“mono”) DON NOT buy that one, is useless;

2) buy a Behringer HD 400 hum destroyer (do not pay attention to the fact that is Beh*, is just a box with two transformers and some resistors/caps in it, you will smash your head against the wall how good it sounds) – around $29.

You have saved one buck for the road 🙂

Now, connect your microphone to your valve preamp, connect the wall wart to the preamp and then stick it into the wall (if you are doing it the other way, you may see nice sparks when the power plug touches the preamp case, which is nice though 😛 ).
Connect your short cable to the XLR valve microphone preamp output and the jack to the “INPUT 1”. It is important to use the “INPUT 1” port, since this is the only one that provides grounding for the case (clever design, to avoid any ground loops, btw).

Now connect another balanced/unbalanced jack cable to your computer interface, mixer or your guitar combo.

Miracle, THE HUM IS GONE !

Earth hour 2012

Earth hour 2012

Today we could do something special.
Power down your studio monitors, unplug your tube guitar combo, shut down your computer, take a candle and get out.

Yes, out, as in OUTSIDE.
You are allowed to have the video camera or your portable sound recorder with you.
Do whatever you feel like, but studio off.

Have a nice Earth hour day,
