DESCRIPTION
INTRODUCTION : In a rather astonishing series of demonstrations
conducted throughout the U.S., AKG recently put inventory
samples of its new 0-300 Series microphones through an
incredible ordeal of abuse. Sample units were intentionally
dropped from heights of six feet or more, repeatedly struck
against hard surfaces and purposely subjected to some of the
most outrageous treatment ever inflicted on microphones. Oespite
incurring some cosmetic damage, each unit not only
"bounced back" in working order but - even more important
- each performed with the sound quality and finesse normally
associated only with a more delicate studio microphone.
While AKG does not advocate intentional abuse of any microphone,
it nonetheless held these demonstrations to dramatize
an extremely important point: That, with the development of
its 0-300 Series, it has succeeded in creating a radically new
and vastly superior generation of musicians' and broadcast
microphones - the very first instruments of their kind to successfully
blend the wide-range response of a studio microphone
and the virtually indestructible toughness of a field microphone
with one of the most comprehensively effective systems of
shock/noise rejection ever devised. Further enhancing these
combined factors are the 0-300s' distinctive styling, comfortable
balance and easy-to-service modular construction.
These remarkable design goals were achieved only by breaking
away from established industry concepts. After carefully evaluating
the real-world needs of touring vocalists, instrumentalists
and their sound engineers, AKG developed several unique (and
patented) acoustical, electrical and mechanical configurations
from the ground up to meet those needs.
As a result, the 0-300 Series is a family of microphones that
will surely set the performance standards of the pop-music and
broadcast industries for years to come. Elegant, yet bulldogtough,
these units are capable of satisfying the most subtle
artistic demands in the studio while shrugging off the daily
abuse, rough handling and various forms of noise that are all
too common in remotes, road shows, club dates and the like.
Furthermore, the 0-300s' simplified field-serviceability now
makes it unnecessary to carry an arsenal of bulky and expensive
backup microphones on tour.
PERFORMANCE : The 0-330BT is the premier model in the
0-300 Series, and embodies all of the uniquely sophisticated
design principles that went into the creation of the series. A
fully professional instrument whose frequency range, transient
response and tonal flexibility are on a par with those of the
very best studio dynamics, the 0-330BT surpasses the most
challenging demands of top vocal and instrumental artists.
With its variable bass·versus·distance contour (marked
emphasis or "proximity effect" when used close up; progreso
sively diminishing bass response when used farther away) and
smooth presence·rise contour (for added crispness and
"punch") plus nine different combinations of bass-rolloff/
presence-rise equalization, the 0-330BT is the ultimate creative
tool - one that offers its users unrivalled personal control
over the tonal "shading" of voices or instruments to suit
any conceivable locale, or any musical mood and style.
It is also noteworthy that the 0-330BT - unlike competitive
microphones - preserves critical signal-to-noise ratios in all of
its equalization modes. This is due to its specially designed filter
networks, which maintain constant midband sensitivity and
assure minimum midband impedance variations in all possible
combinations of bass and presence settings.
In addition, the 0-330BT's hypercardioid directional pattern is
far more discriminating than that of a standard cardioid and is
also unusually uniform with respect to frequency. These characteristics
- extremely important in broadcasting and utterly
indispensible for sound reinforcement - produce negligible
coloration of desired sounds at the sides of the microphone
while providing exceptional (and highly predictable) suppression
of unwanted acoustic feedback and backgrou nd noise
towards the rear of the microphone.
DESIGN/ CONSTRUCTION : What sets the 0-330BT apart,
however, is not merely its superb performance. Rather, it is
the combination of that performance with its unmatched
ruggedness, totally unprecedented noise-rejection capabilities,
fatigue-free handling, comfortable balance and extraordinary
ease of field service. The key to all of these factors is readily
apparent in the exploded view below and in the detailed
"walking-tour" description that follows overleaf.

DESCRIPTION (Continued)
The microphone's unique design and construction begin with
an unusually sturdy three-layer windscreen/pop-filter assembly .
This assembly consists of a shock-absorbing stainless-steel
wire-mesh outer layer, a blast-diffusing fabric middle layer and
reticulated polyurethane-foam inner layer (sandwiched together
into a removable liner) plus a threaded retaining ring that
secures the entire unit to the microphone housing. So effective
is this combination in reducing the effects of wind noise, breath
pop and similar acoustic interference, that an external wind
­
screen or pop filter is seldom, if ever, required.
As tough as the windscreen/pop filter is alone, it is further
reinforced against impact damage by a special safety-basket
assembly. Note that the safety basket is contoured to support
the inside of the windscreen/pop filter and to surround the
front of the transducer system - thus also isolating all internal
parts from head-on impact damage. As shown, the safety basket
consists of a resilient dome-shaped ribbed cage joined to a
reinforced open-frame casting. Fitted with a fine-wire -mesh
screen that coincides with side ports in the microphone housing,
the casting also has indexing notches that align the entire
rugged assembly with structural members in the microphone
housing.
Next in line is the totally unique transducer system. In terms
of its superb performance, its extraordinarily thorough shock
and noise suppression and its modular field-serviceable packaging,
the system is a prime example of the care and the attention
to deta il that AKG engineers lavished on the D-330BT.
To start with , the transducer system "floats" uniformly in all
directions within the microphone housing for unprecedented
isolation from the effects of impact damage, handling noise
and spurious vibrations . This is achieved by two special ringshaped
elastomer suspensions - one near the front of the system
and the other at the rear of the system . To combine the
advantages of both hard and soft suspension designs , each of
these ring suspensions has a dense, relatively hard body and a
series of compliant, progressively compressible dome -shaped
projections around its periphery - in effect forming a complex,
highly damped low-pass mechanical filter. Therefore, under
normal handling conditions, the compliant domes effectively
decouple the transducer system from mechanically and motionally
induced vibration. Further, under extremely abusive
conditions (dropping the microphone or subjecting it to lateral
impact), the domes increasingly compress, in proportion to
applied g-force, in a progressive braking action - ultimately
allowing the harder body of each suspension to act as a bumper .
These extraordinary suspensions, however, are only part of
AKG's comprehensive scheme of noise suppression. Note that
the transducer system uses two generating elements - the main
front-facing sound-pickup transducer !computer designed for
widest possible frequency range and superb transient response)
plus a special rear-facing nonacoustic (sealed) noise-compensating
transducer . Working together, these transducers further
reduce the effects of mechanically and motionally induced
handling noise by an additional 30 dB at 100 Hz. In this unique
arrangement , the two carefully matched tr ansducers are wired
in parallel and electrically in phase but - because of their opposed
orientation - operate out of phase. Thus, any handlingnoise
signal generated by the main transducer is nulled by an
equal but opposite handling-noise signal generated by the compensating
transducer (which acts strictly as an electromechanical
motion-sensing accelerometer). As still another precaution,
the main transducer incorporates a hum-bucking winding to
cancel the effects of electromagnetically induced noise from
ever-present power and lighting cables as well as from dimmers , power switchboards and the like.
The two transducers, together with the three-position presence­
rise switch and its associated filter network, are encapsulated
, in a replaceable plug-in module. Injection-molded of stress­
resistant thermoplastic, the module is fitted with a special low
­
noise two-contact female audio connector precisely aligned
and keyed to mate with a special two-pin male connector (and
the three -pos ition bass-rolloff switch with its filter network)
within the microphone housing,
The microphone housing itself is a lightweight, yet impac t
­
resistant zi nc-a lloy casting - elegantly styled, carefully balanced
and finished in glare-free matte nickel. For maximum wear
resistance, the finish is electroplated (not merely painted, as
on competitive microphones). In conjunction with the windscreen/pop filter and the safety basket, this housing effectively
encapsulates all internal parts against metal particles, dust and
moisture spray,
Should field service ever become necessary, the windscreen/
pop filter can be quickly unscrewed, the safety basket easily
lifted out, and the transducer module simply unplugged and
withdrawn from the microphone housing for replacement.
Spare assemblies and parts are readily available.
The D-330BT is a low-impedance balanced-output unit fitted
with a standard 3-pin male XLR-type connector. The microphone
is supplied complete with an SA-31 stand adapter and
a foam-lined vinyl protective case. Several optional accessories
- listed in the Technical Data section - are available .

DESIGN/CONSTRUCTION : To achieve all of the characteristics out ­
lined or specified up to this point, the microphone shall consist of four
special modular assemblies interrelated as follows: 111 a removable
shock -absorbing three~ayer windscreen/pop filter; 12) a removable
safety basket, internally reinforcing the windscreen/pop filter and protecting
the front of the transducer system; (3) a specially suspended
and vibration/hum-compensated plug~n module, containing the transducer
system plus the presence..-ise switch with its associated network ;
(4) an impact-resistant main housing, mating with the first three assem ­
blies and containing the basHolioff switch with its associated network

The three-layer windscreen/pop-filter assembly shall effectively suppress
wind noise, breath pop, and similar acoustic interference, and
shall also partially isolate the transducer module from the effects of
head-on impact damage. The assembly shall consist of a shock-absorbing
slainless.,;teel wire-mesh outer layer, a removable liner made up of a
blast-diffusing fabric middle layer sandwiched with an open-cell reticulated
polyurethane-foam inner layer, and an internally threaded retaining

module from, the effects of head-on impact damage . The safety basket
shall consist of a resilient dome-shaped ribbed cage, joined to a rein ­
forced truncated-conical open-frame casting fitted with fine-wire -mesh
screen to coincide with side ports in the main housing and having indexing
notches to align the entire assembly with structural members in the
main housing.
To further isolate the transducer module from the effects of impact
damage, as well as to reduce the effects of handling noise and spurious
vibrations, the entire module shall float uniformly in all directions within
the main housing. This degree of isolation shall be achieved by means
of two special ring-shaped elastomer suspensions , one fitted around the
module near its front end , and the other fitted to the module at its rear
end, To combine the advantages of both h ard and soft suspension designs
in the form of a comple x, highly damped low..,ass mechanical
filter , each of these ring suspensions shall have a dense , relatively hard
body and a series of compliant, progressively compressible dome-shaped
projections around its periphery that shall function as follows : (1) under
normal handling conditions , the compliant domes shall effectively decouple
the transducer module from mechanically and motionally in ­
duced handling noise ; (2) under ex tremely abusive conditions (e,g "
dropping the microphone or subjecting it to lateral impactl , the domes
shall increasingly compress, in proportion to applied g-force, in a progressive
braking action that shall ultimately allow the harder body of
each suspension to act as a bumper.
To further reduce the effects of mechanically and motionally induced
handling noise by an additional 30 dB at 100 Hz, the transducer module
shall employ twO coaxially mounted moving-coil transducers working
together in a special no ise-bucking arrangement. One transducer shall
serve as the main Isound ·pickup) device, and the other transducer shall
serve as a special electromechanical Inonacoustic} noise-compens3ting
device acting strictly as a motion-sensing accelerometer. The main
transducer shall be positioned closest to the front of the module , shall
face forward, shall be computer-designed for widest possible frequency
range and optimum transient response, shall employ a nonmetallic
MAKROFOL TM diaphragm , and shall further incorporate a humbucking
winding to cancel the effects of stray magnetic fie l d ~ from
power and lighting cables, dimmers, and power switchboards. The noisecompensating
transducer shall be positioned behind the main transducer ,
shall face rearward, and shall employ a nonmetallic MAKROFOL ™
dummy diaphragm having exactly the same mass and compliance as the
main transducer's diaphragm. The two transducers shall be connected in
parallel and electrically in phase (i.e., inward direction of diaphragm
movement in each shall generate like polarity of output signal from
each I. However , because of their opposed orientation, the two tran s·
ducers shall operate effectively out of phase so that any handling-floise
signal generated by the main transducer shall be nulled by an equal but

AVIS GLOBAL

Utilisé régulièrement en concert ou répète depuis + de 15 ans, en tant que musicien amateur ou en tant que sonorisateur amateur. Donc plusieurs 100aines de presta.

Un peu faible en terme de sensibilité au regard d'autres micros de catégorie un peu " supérieure " (genre Béta 58 ou N/D767A) ou même de micros plus récents de catégorie " inférieure " (E845, D880, etc.), mais sa technologie date qd même de 20 ans.
Nota : il ne favorise pas pour autant le larsen, ce qui peut sembler assez étonnant.

Vraiment très costaud (c'en est même impressionnant, le seul type de micro dont je n'ai jamais eu à changer de bonnette), avec une finition impeccable.
Son plutôt clair et précis, restitution " plate ".

J'en posssède 4 qui me servent essentiellement pour la reprise de CC et de toms en concert, en cas de batteur pressenti comme bourrin ou maladroit (faut parfois savoir économiser ses micros plus fragiles et plus chers, surtout en tant qu'amateur et bénévole)
Dans ce mode d'utilisation, il est un peu moins riche et fin qu'un M201N C, mais nettement plus efficace qu'un cardioïde dy type SM57 (meilleure immunité aux sons environnants, restitution plus large et plus fidèle)
Utilisable aussi, en dépannage sur charley ou ride.
Techniqt intéressant pour le chant (très resistant aux plosives, peu d'effet de proximité notable dans mes souvenirs, même sans coupe-bas), il fut un temps où je l'ai plutôt utilisé pour le choeur individuel que pour du lead, ce en raison de sa sensibilité un peu faible et de son léger déficit dans le médium.
Bon souvenir en reprise d'ampli guitare.
Pas de mauvais souvenir (mais c'est lointain) sur des cordes acoustiques. Jamais testé sur du vent (cuivre ou bois)
Dans tous les cas, préférable à mon avis à un SM58 card ou même à son neveu scard de chez AKG, le D880 (trop sombre et pas assez précis à mon goût)

Trouvable d'occase, à des prix allant du assez ridicule jusqu'au très accessible (entre 40 et 80 € env) par rapport à la qualité du machin.

En résumé, un micro scène ancien mais très polyvalent et assez pratique, plutôt fidèle en restitution sonore, très efficace dans les aigus (pour un dynamique), mais un peu faible en signal.
Très bon rapport qualité/prix.

Micro dynamique cardio avec filtre coupe bas (3 positions) haut (3 positions). Orienté chant et scène, mais utile pour rprendre un ampli guitare.

AVIS GLOBAL

Je l'ai trouvé il ya deux jour chez cash converter ( 12 euros, ils vendent cher des merdes, et des fois, par ignorance, pas cher des super trucs ). Comparé à mon SM 58, il lui est supérieur (largement), je le préfère au beta 58 également. C'est une très bonne surprise d'autant plus que je ne le connaissais pas.

Le rapport qualité prix est fabuleux (le mien est dans un état impeccable, le câblage est nickel.

C'est un micro dynamique assez universel, qui a quelques années maintenant, on ne le trouve plus dans le commerce je crois...
Il possede 2 filtres intégrés...Passe bas, passe haut...

AVIS GLOBAL

Je l'utilise depuis 12 ans, il est super costaud, tres bien pour les guitares acoustiques, pas mal pour la voix surtout sur scene...A l'époque il était assez cher dans les 1500 F en 1990! Mais bon pour la différence de prix minime je ne serais pas allé vers un shure beta 58...
Son assez chaud...
