I forgot to mention that if you scroll through the photos of the album and click once on the little "i" (information) circle in the top right corner of the screen, you will get useful descriptions for

Hi Damian Magnus Bergsson shared a photo album about his NT1a approach. You'll find it here: Rode NT1a modified for nature recording (

With mic capsules that size... for wind protection? you're going to end up housing them in a standard zeppelin, sideways. That's hardly discreet ;-) Anyway, I don't think there's much

@Cram, thanks for the links. The rig you're making looks cool. I hadn't thought about being limited with the capsules in a blimp, I guess I just assumed I could manage an ORTF arrangement. The mics

I hear you. I’ve got a few omnis (em272 and aom5024) in various configurations, but I’ve been wanting to play with some cardioids also for ambience and nature sounds etc. The self noise specs of

@Cram, I'm dismantling them to make the whole thing a bit more portable. I like the idea of something I can set up fairly quickly- then it will get used and my laziness or procrastination won't put a

I’ve just sourced a pair of old nt1a’s to run in a stereo field rig also, but I’m making individual blimps for them. If you’re going to be using the f3, is there a need to dismantle the mics?

Hi all. I spotted an old youtube video recently, where the guy dismantles a pair of Rode NT1a to capsule and pcb, and fits them in a blimp, and I'd like to do something similar. I have a pair of LDC

Got it, thanks for the education. There is a splice near the capsule, now shielded, and a splice near the plug which is not

Well, the posted Alctron MA-1 schematic certainly has at least one error! The idents of Q3 and Q4 are reversed. As Jerry has surmised, the cascode amplifier inverts the signal. I can confirm that the

Yes indeed.

No: there is no body -- well, no metal body; it's inside a bakelite antique wall-mounted telephone mouthpiece. I was under the impression that a 2-wire PiP capsule acts as its own shield so I didn't

Not in normal circumstances. Are you sure that the body in which you put the capsule is properly grounded?

I was somehow stuck on the idea that it's a mono connection. Don't know why ? Glad the shielding works.

Thanks Chris and Jerry: Jerry wrote: It's a two-wire capsule (JLI-61A <https://www.jlielectronics.com/content/JLI-61A.pdf>) -- AFAIK the ground terminal is connected to the capsule body in that

It seems to indicate that the capsule body is not properly grounded. In 3-wire connection, there is no need to shield teh capsule, as long as the body is connected to teh shield. Check your

It is not stereo, it is standard PC microphone wiring of a TRS jack, sleeve is shield + signal and power return, tip is signal, and ring provided power for a capsule with built-in FET. The Amazon page

Progress! Aluminum foil wrapped around the capsule body (but not covering the face of it), which covers the wire connections to the capsule from the wire, makes the hum disappear. I'll solder in some

Get a mono plug. It'safer. How is the capsule shielded? Cover the capsule with an empty can. If the hum is gone - you have improperly or insufficiently shielded capsule.
