| New
"Meekrophones" From Joemeek |
|
|
The
first two models (JM27 and JM47) of a new generation
of Joemeek products, affectionately called “Meekrophones” are
beginning to ship. Offered at just $129 and $299
(list), they mark a real value for recording
enthusiasts.
Offered in both satin silver and “Joemeek Green”, The
JM27, is a medium sized diaphragm, true capacitor cardioid
mic. With a frequency response of 30Hz to 20KHz, and capable
of handling levels up to 130db, it is capable of a wide
range of uses – from acoustic instruments to drums. The
JM27 ships with a microphone clip, foam wind screen, and
manual.
Available in satin silver only, the
JM47 boasts a large 1” diaphragm, cardioid pattern with
FET impedence converter and transformer output. The transformer
is double shielded for better RF rejection. By using
a center electrode capsule design the JM47 exhibits extremely
smooth extended frequency response (20Hz to 20KHz) while
rejecting low frequency “boominess”. Sensitivity is rated
at –36dBV and signal to noise ratio at 75dB. Switches
for a –10dB pad and high pass filter round out the feature
set. With a US retail price of $399, including a heavy-duty
mount and foam wind screen, it's an excellent value low
budget recording.
Both the “Meekrophones” use gold sputtered
micro-fine Mylar membranes (much more robust than traditional
gold foil), and are contained within high quality, machined
brass bodies. Audio quality is further enhanced by using
dynamic feedback at the capacitor element, an original
Joemeek design. Elastic shock mounts are available for
both models for a small additional charge.

| Compressors:
Dispelling the Mystery - By Allan Bradford |
|
|
The Compressor is one of the most vital
pieces of equipment in any studio or PA rig, yet it is
one of the hardest to understand. Here Joemeek designer
Allan Bradford dispels the mystery.
The Compressor's job is to make quiet sounds louder and
loud sounds quieter, or in other words to reduce the
dynamic range of programme material. It's a bit like
manually riding the volume control, except a compressor
does it automatically, responding far quicker and more
accurately than you ever could by hand.
Compressors have many uses in practice, applied either
to individual parts, or to the whole mix:
1. Making Things Stand Out
Because compressors make loud sounds quieter, you can
boost the volume of the quiet bits without the loud bits
getting any louder. That means you can raise the average
level of an instrument or vocal in the mix, which has
the effect of lifting it and bringing it forwards. This
can actually improve vocals, bringing them out in front
of a mix, making them sound denser, more even, and more
confident!
2. Cranking Up The Volume
Raising the average volume of whole mixes means they
can be heard in noisy environments, such as vehicles
and factories. Boosting the average level is what makes
radio stations sound LOUD! The same technique is used
on TV commercials too, which is why they always kick
in annoyingly louder than the movie you are trying to
watch!
3. Protection
When an occasional loud peak sticks its head above a
maximum permitted level, the compressor quickly clobbers
it ¯ this is known as limiting and a compressor
designed solely for this purpose is known as a Limiter.
Limiters are primarily used to protect recorders and
monitor systems from overload, radio transmitters from
overmodulation, etc. Normally you should not be able
to hear a limiter operating but if it is driven hard
constantly, it can render a mix somewhat flat and lifeless.
4. Accommodation
The dynamic range of the human ear is phenomenal, extending
from the threshold of hearing (eg: a pin dropping onto
soft carpet) to threshold of pain (eg: standing next
to a jet aircraft) - some 120dBA in all. By contrast,
vinyl, cassette tape and radio broadcasts all have a
dynamic range of about half that. Since the advent of
the CD, the dynamic range of the medium is far less of
an issue and compressors are used more to give a certain "feel" to
a production. AM and FM radio however, is still very
much compressed to fit its restricted dynamic range.
5. Modification
A compressor can change the dynamics, or "envelope" of
the track and it is here that Joemeek Compressors excel.
For example, with extreme settings it is possible to
make a drum hit appear to go backwards!
Next time we'll look at what the controls do on a typical
compressor.

Projects Microphones Used For Grammy Nominated Bluegrass
Release |
|
|
“Christmas on the Mountain”, Scott Rouse ¯ Producer
picked up a Grammy nomination for Bluegrass Album Of
The Year in January of this year.
The first Christmas release on Universal South, a joint
venture between industry pros Tony Brown, Tim DuBois
and Universal Records,the album was conceived as a giant
jam session, gathering together bluegrass greats for
inspired takes on holiday sounds.
Featuring an all-star lineup including Doc Watson, The
Del McCoury Band, Ronnie McCoury, The Groovegrass Boyz,
Mac Wiseman, and The Osborne Brothers, takes a new approach
to “seasonal” music.
Known as an innovative and inspiring producer, Scott's
discography reads like a “Who's Who” in the
music industry. Alan Jackson, Travis Tritt, Charlie Daniels,
Marshall Tucker Band, Bootsy Collins, The Beach Boys,
House of Pain ¯ the list goes on and on.
Scott used a pair of Studio Projects C4's through Joemeek
VC1Q's when recording Doc Watson's acoustic guitar and
Ronnie McCoury's mandolin. For Mac Wiseman's vocal, the
C3 got the nod as the microphone of choice. Scott once
again routed it through the Joemeek VC1Q, with an older
Joemeek C5 EQ to add tube warmth at the end of the chain.
Asked for a comment on the mics, Scott had this to say. “If
you want a bluegrass guitar or mandolin to sound like
it's going to jump right out of your speakers and kick
you in the nuts, check out a pair of C4's!” And
he should know, he's produced some of the best (and most
famous) bluegrass musicians in the world!

| A
Discussion of Microphones and Acoustics- by Brent Casey |
|
|
There are several key factors that fuel an ongoing debate
regarding the evaluation of condenser microphones:
1. Microphones of increasing quality and sophistication
are now within the financial grasp of a wider populace.
2. Microphones and mic companies are more plentiful than
ever
3. All of our computers are connected together online,
facilitating a constant global discussion of various
models, technique, the men who use them and the women
who loved them before they started buying all this gear,
etc.
So why all the debate? First of all, let us list the
things in which we can all agree upon regarding these
devices:
-Microphones change acoustical energy into electrical
energy
-There is no such thing as an ideal microphone.
The first point is simple and easy to understand. It
is a basic definition of what a microphone does. The
second point provides a basis for a great deal of discussion
pertaining to microphones, although it is generally not
phrased in such a way. There are also many other factors
thrown in regarding brand preference, marketing, hearsay,
magazine and online reviews, testimonials by big time
recording engineers, etc. Let us ignore all that. Furthermore,
we shall put aside microphone designs for more specific
applications and environments.
Now then, even the most expensive, well designed, solidly
built microphone in the known universe falls way short
of being an ideal transducer. Most mics intended for
pro audio use attempt a fairly linear bandwidth across
audio frequencies, low noise, high sensitivity and high
sound pressure handling capabilities. There are any number
of mics from many different manufacturers which achieve
all of this very well. Still, one may note that there
are highly cherished models of microphone which may fall
short in one or more of these areas, yet still be preferred
over a mic with better specifications. So, what is the “inferior” mic
doing which makes it the go-to selection? The answer: “It
tells a better lie”.
