Reviews Summary for Neumann U87Ai Large Diaphragm Microphone
Neumann U87Ai Large Diaphragm Microphone Reviews: 3 Average rating: 5.0/5 MSRP: $2,799.95
Description: Over 50,000 U87 users can't be wrong, this microphone is the professional standard and sets the mark by which all others are measured. The U 87 will celebrate its 40th birthday in 2007 and is still going strong.

The U 87 is probably the best-known and most widely used Neumann studio microphone. It is equipped with a large dual-diaphragm capsule with 3 directional patterns: omnidirectional, cardioid, and figure-8. These are selectable with a switch below the headgrille. A 10 dB attenuation switch, located on the rear, enables the microphone to handle sound pressure levels up to 127 dB without distortion. Furthermore, the low frequency response can be reduced to compensate for proximity effect.

The studio microphone classic

3 directional characteristics: omni, cardioid, figure-8

Switchable low frequency roll-off

Great! If you can afford one go for it.  Time owned: more than 12 months
My, my. A Neumann U87? For ham radio? On HF?

I saw this review, and since I have access to many mics, including the U87 I decided to try one with my Tentec Orion. I know how they sound in a studio environment (if used properly it's the gold standard-every one has heard one if they listen to any music at all). So I connected it, used an Orban 787 mic processor to add phantom power and feed the rig and the genuine Neumann wind/blast/pop filter.

It was my turn to be net control that night. Every person on the net made an unsolicited comment of how much fuller my audio sounded than usual. Most people were guessing I got a new rig. The regular mic is a Shure SM-7 with the Orban 787 and was surprised that anyone would hear the difference. But they did!

If you can afford a mic that costs more than most HF rigs, and you really are into audio vanity, hey(!)go for it.

Wasteful overkill in the ham shack...  Time owned: more than 12 months
This is an excellent microphone. SSB uses very little speech frequency audio bandwidth, about 2800 Hz, so virtually any good quality microphone costing more than $10 will sound good on pretty much any transceiver. Sheesh, practically ANY microphone will show a flat, linear response curve across this frequency range. This is an excellent microphone for recording studios, where ambient noise is suppressed, but this type of microphone is generally so very sensitive, it will pick up the sound of a gnat's sneeze across the room, so it will also pick up loads of ambient noise from within the shack, such as power supply and computer cooling fans, aong with the sound of your voice, and that will NOT bode well for clear, intelligible speech communication. Great mic for the studio... lousy pick for the shack. So, yeah it will work, but is not really the best tool for the job, despite its reputation in the studio, and, of course, the exorbitant cost.

PS - I concur with everything W8AAZ says below.

Happy trails and good DX. // K8JHR //

Not a Ham mike unless you are AM freak.  Time owned: more than 12 months
This might be something a very rich AM'er working for the last little bit of HIFI in his classic station might try, but it is for recording studios, not broadcast or ham. Although Howard Stern uses one. Want to be like him? I had one and eventually sold it for a nice profit. Super studio mike. But for ham use you might as well forego a phantom power condenser and get something like one of the EV broadcast dynamic mikes for alot less. And for SSB get something like a Heil for vastly less, or a Shure 444 or a Ten Tec desk mike. Or play with an old Shure 55, a ribbon mike, or anything. This costs more than most radios. Keep for your home studio.
