And, checking my archives, I found that M71 review!
Perestroika Mics Deliver Neumann Sound
Ty Ford, Baltimore, MD
When it was announced earlier this year that Sennheiser had acquired
Neumann, many questions were raised about the future of the
distinguished Neumann line of microphones. One of the most important
questions for Gotham Audio (now Gotham Technology Group) in New York
was, "What Next"? After all, Gotham had been the long-time distributor
for Neumann.
Microtech Gefell
I got my answer from Gotham's Jerry Graham at the most recent AES
convention in New York. Gotham has made arrangements with Microtech
Gefell of East Germany, to distribute three microphones that were
originally designed by Georg Neumann, but that have been "lost" behind the
German Wall. The UM 70S ($1150), UM 70 ($995) and M71 ($795) are all
priced under the $2200-$2400 to which Neumann mics have been raised
within the last year or so.
Positioned as the "Perestroika Microphones", the mics are built with
Neumann's M7 large diameter dual membrane capsule. In case you're
thinking that this is just another noisey "old technology mic" trying to
hang on in a digital world, you're wrong. The mic's internal amplifier
system has an FET input stage coupled to a hybrid amplifier specially built
for the M7 capsule and requires phantom power. Both mics I tested were
plenty quiet.
THE NEUMANN SOUNDPRINT
While the price, heritage and technical evolution of these mics are
important, the big question is, "What do they sound like?" Having heard my
own voice on many different high quality mics over the years, I knew I
was speaking into a Neumann the instant I heard myself in the headphones.
If you know the sound, you know what I'm talking about.
I arranged for a evaluation session with Louis Mills at Flite Three in
Baltimore. Again the sound of these mics was immediately recognizable as
Neumann. Even with the typical EQ changes Mills applied to bring out the
voice a bit more, the Neumann soundprint was evident, which brings me to
an important point.
PROBLEMS
A few years back, before the economy began to wither, a lot of radio
stations replaced their dynamic mics with Neumann TLM 170, U87 or U89
mics. I've heard from a number of these people who were ultimately
disappointed with the performance of these mics. They complained that
these mics weren't bright enough, that they sounded bad when worked
"close", and that they picked up everything in the room, including aging
cart machine bearings and air conditioner noise.
SOLUTIONS
Part of the close-working problem was that the high output of these mics
was overdriving the mic preamp. Complaints about lack of brightness came
from situations where the mics were just plugged into the board without
any EQ. I think a lot of radio station people saw the aforementioned mics
being used to record voice at recording studios and assumed that all they
had to do was plug them in to the console. Bad assumption.
The rule for this kind of operation is very simple, any time you work a
close mic using a large diameter condenser mic with a cardioid pattern,
you're going to have to roll off the low frequencies that are picked up
when you're that close to the mic. Most engineers also peak the 3KHz to
6KHz a few dB, which allows the voice track to cut through better.
I'm not suggesting that you'll be happy just plugging the UM 70S in without
EQ, but I was happy with the sound without EQ on both my voice and
another voice. Both mics have a richness in the lower midrange (part of
the Neumann soundprint) that gave my voice a cross between power and
presence, without the "boominess" most mics create by having too much
bottom.
Incidentally, the next time you compare mics for voice-over work, try
each one over the same selection of music beds. Both Microtech Gefell
mics I worked with sounded, less "beefy" and not as bright as some typical
voice-over mics, but that extra energy in their lower midrange really does
put your voice "out front". In fact, working with these mics has changed
my entire approach to voice EQ. Like a lot of people, I typically mess with
the 100Hz-200Hz and 3KHz-5KHz ranges. These mics taught me that there
is a lot of power in the 800Hz-2KHz range that I had overlooked.
PATTERNS
The M 71 is a fixed pattern cardioid. The UM 70 and the UM 70S are three-
pattern switchable; omni, bi-directional and cardioid. The slightly more
expensive UM 70S is a bit quieter version of the UM 70. The omni pattern
has very good polar response, with the high frequencies dipping only
slightly at thirty to fifty degrees off-axis. The bi-directional pattern has
great nulls and very uniform frequency response from front to back. All
three mics have -10dB pad and bass roll-off switches. The MKV 8
swivel/stand adapter and the WS 86 acoustic foam wind and pop screen
come with each mic. All three mics are shipped in classy little foam lined
wooden boxes.
Gotham strongly suggests that you use their three-conductor, double
reusen layer shielded cable. Although I had no problems at my studio with
my own cables, using the house cables at another nearby studio turned the
mic and cable into a great R.F. noise antenna. Switching to Gotham's cables
eliminated the problem. Gotham makes these cables in black, red, yellow,
green, blue and gray. A ten foot cable with XLR connectors runs $25.00,
with twenty-five and fifty foot extensions at $35.00 and $45.00
respectively.
The EA25 elastic suspension ($125) is optional, $100 if you order it with
the mic. Reaching in through the cat's cradle of elastic bands to close the
clasp took a little getting used to. Orthodontists should have no trouble
with it.
The proof is in the product. I'm currently using these mics on my voice for
radio spots which run from Boston to Richmond, and on other voices in the
Baltimore/Washington area. I use more than the average amount of clean,
high-speed compression and limiting. The soundprint remains
recognizable. You owe it to yourself to hear these mics. For more
