Trying to find vintage wireless microphone

Postby shoom » Thu Apr 22, 2021 12:11 pm

Hi there all,

I am trying to find out what type of microphone is a long handled interview type wireless microphone for live TV broadcast from the late 70s / early 80s ...

The mic itself was about 4 or 5 feet long and was white in colour and looked like it could have been made out of plastic or aluminium . The mic in question I'm sure was intended for presenters to be able to interview someone sitting a couple of aisles away without having to reach , which is exactly how I saw it being used on a sports show of the era (of which I have forgotten which or what type.) Maybe the battery(ies) were in the handle.

I hope one of you can help me find the make and model, as so far I havent been able to find anything!

And thankyou in advance to the moderator just incase this is in the wrong forum, and I hope you can find the correct place for it,,

Kindest Regards.

Are you talking about seeing this in the UK, or Europe, or the USA? The location will affect the likely options significantly.

I don't know of any interview mic being 4-5 feet long. I suspect what you're thinking of is a standard radio-mic mounted at the end of a short 'fishpole' boom.

I visualised a longer version of Terry's 'Blankety Blank' mic (which I think was just a prop?) but IIRC the BBC used floor standing interview mics with the capsule remote from the body on a chrome extension so could it be something like that?

That was AKG's CMS system where you could mix and match a couple of different C451 preamp bodies (silver or black, with or without high-pass filter switches), with a wide range of different CKn capsules*, A51 'knuckles' to angle the capsule from the preamp, in-line 10dB or 20dB pads that screwed between capsule and preamp, and then the short VR1 and long VR2 extension tubes.

Scarily fine threads that were easily cross-threaded if you weren't paying close attention, but a really versatile system that was used extensively throughout BBC TV in the Centre, Nations and Regions.

*The ones I remember are the standard CK1 cardioid, CK2 omni later replaced with the much longer CK22, CK3 hypercardioid, CK5 (cardioid with a bog mesh pop screen for vocals), CK8 (short shotgun), CK9 long shotgun, and the rare Ck4 fig-8 capsule.

You can see the mic and top end of a VR1 in the videos Sam Inglis does, e.g.

I have a couple of old AKG C451/CK1 mics, the threads are very fine. but most similar threads, even SM58 baskets, are pretty fine.

That does indeed look like the setup...

I think the CK1 threads were the finest I've ever worked with. When the 451 was replaced with the 460 (and then the 480) series, they changed to a much coarser pitch which made them far more robust and reliable.

I always preferred the original Calrec modular mics which used something akin to standard British Gas pipe threads! Very chunky!

Agreed!!

Regarding the OP, if the CK capsules + VR1, VR2 extension tubes + preamp are what you saw they wouldn’t be wireless.
