PZM

Description

PZM (Pressure Zone) Microphones are a special type of condenser microphone. Also known as a boundary microphone, this type of microphone uses a sound phenomena called the boundary effect. PZM mics are quite unusual-looking. They are flat and don't really look like microphones at all.
A boundary microphone (or pressure zone microphone) is one or more small omnidirectional or cardioid condenser mic capsule(s) positioned near or flush with a boundary (surface) such as a floor, table, or wall.

Improvising a PZM or boundary microphone

Hi,

I will be doing the sound recording for an upcoming "making of" of a large BluRay concert production. We want to be able to record as much talking amonst the artists as possible, whilst not disturbing them or their mood.

For this project I will use a normal boom microphone where applicable, but I would like to be able to drop a boundary (layer) microphone/pressure zone microphone on the table without much ado where the situation calls for it.

Hi,

After 15 years in the garage, I just found an old pair of Radio Shack PZM mics I had forgotten about. I forget the details, but I seem to recall that they were like $30 ea and this version was considered -very- close to the pricey Crown models. I must've done -some- sort of wiring on the jack because they now have XLR connectors. I must've experimented with them a few times, not had a clue what to do and forgot about 'em.

Pressure Zone Microphone. Also know as a boundary microphone. The microphone consists of electret capsule mounted to a backing plate, which is then placed on any kind of flat surface. Useful for conferences, ambient microphones or for recording piano where isolation from other sources is essential.

Home made PZM?

Having looked closely at the design of my 'Realistic' PZM I was wondering if anyone had tried mounting a small diaphram mic very close to a large flat surface or plate to obtain the same effect.
Why? Firstly you could swap different mics, and secondly all the sig/noise benefits.
I imagine setting the distance from the plate might need some fine adjustment. I think I might experiment and mount a mic holder onto a flat steel plate.
No doubt, someone has tried this before or similar. Any thouhts? Dave.

PZM's as overheads?

G'day analoggers and numberjacks.

So I was reading that PZM's have no proximity effect. I understand they also have no directionality to them.

Therefore I was wondering if anyone had tried them in the role of drum overheads, and how they do in that capacity?

Seems like you'd get a situation where your overheads had the whole spectrum, with a lot of 'room' in them.

Hmmmmmmm...

PZM's for drums?

Hi folks,
I'm new in here, and also totally new with recording.
I recently bought a Yamaha AW16G( known better as "G") and am trying to record my band. Mostly I go in direct into the recorder (ie: guitar, bass, key's) but I'm trying out for the drums, 2 PZM's on left and right side of the drums. I have a good AKG for the base. Seems like the cymbals are really picked up, as is the rest of the band..lol, but not very good for the skins. Anybody ever used PZM's for drumkit??
Great site!!

'Optimus' PZM/boundary any good ?

Sorry for this budget-question, but how useful is the boundary ('PZM') mic that Radio Shack has for US$39.99 ?
It's the Optimus #33-3022.

Since someone here will be visiting the US soon I was thinking about asking him to get me a pair.

If you only had 1 Crown PZM mic and were recording a 20-pc jazz orchestra (drums, bass, elec. gtr, piano, keys, perc, 4 trmpts, 5 trmbns, 5 saxes, LdSax, 2 LdVs and up to 8 BGVs) in a live setting....

...where would you use the PZM?
...or would you use it at all?

BTW - your PZM is NOT the only mic you have to work with.....its just an option.
